What is each hemisphere of the brain responsible for? What is the left hemisphere of the brain responsible for?

Ecology of life: The brain is a complex and interconnected system, the largest and functionally important part of the central nervous system. Its functions include processing sensory information from the senses, planning, decision making, coordination, movement control, positive and negative emotions, attention, and memory. The highest function performed by the brain is thinking.

Its functions include processing sensory information from the senses, planning, decision making, coordination, movement control, positive and negative emotions, attention, and memory. The highest function performed by the brain is thinking.

You can easily test which of the hemispheres of your brain is active at the moment. Look at this picture.

If the girl in the picture rotates clockwise, then at the moment you have more active left hemisphere of the brain (logic, analysis). If it turns counterclockwise, then you have an active right hemisphere (emotions and intuition).

In which direction is your girl spinning? It turns out that with some effort of thought, you can make the girl rotate in any direction. For starters, try looking at the picture with a defocused eye.

If you look at the picture at the same time as your partner, friend, girlfriend, acquaintances, it often happens that you simultaneously watch the girl rotate in two opposite directions - one sees the rotation clockwise, and the other counterclockwise. This is normal, it's just that different hemispheres of the brain are active at the moment.

Areas of specialization of the left and right hemispheres of the brain

Left hemisphere		Right hemisphere
The main area of ​​specialization of the left hemisphere is logical thinking, and until recently, doctors considered this hemisphere to be dominant. However, in fact, it dominates only when performing the following functions. The left hemisphere of the brain is responsible for language abilities. It controls speech, reading and writing abilities, remembers facts, names, dates and their spelling. Analytical thinking: The left hemisphere is responsible for logic and analysis. It analyzes all the facts. Numbers and mathematical symbols are also recognized by the left hemisphere. Literal understanding of words: The left hemisphere can only understand the literal meaning of words. Sequential information processing: Information is processed by the left hemisphere sequentially in stages. Mathematical Ability: Numbers and symbols are also recognized by the left hemisphere. Logical analytical approaches, which are necessary for solving mathematical problems, are also a product of the work of the left hemisphere. Control over the movements of the right half of the body. When you raise your right hand, it means that the command to raise it came from the left hemisphere.		The main area of ​​specialization of the right hemisphere is intuition. As a rule, it is not considered dominant. It is responsible for the following functions. Processing non-verbal information: The right hemisphere specializes in processing information, which is expressed not in words, but in symbols and images. Spatial orientation: The right hemisphere is responsible for the perception of location and spatial orientation in general. It is thanks to the right hemisphere that you can navigate the terrain and make mosaic puzzle pictures. Musicality: Musical abilities, as well as the ability to perceive music, depend on the right hemisphere, although, however, the left hemisphere is responsible for musical education. Metaphors: With the help of the right hemisphere, we understand metaphors and the results of the work of another's imagination. Thanks to him, we can understand not only the literal meaning of what we hear or read. For example, if someone says: "He hangs on my tail," then just the right hemisphere will understand what exactly this person wanted to say. Imagination: The right hemisphere gives us the ability to dream and fantasize. With the help of the right hemisphere, we can make up different stories. By the way, the question "What if ..." also asks the right hemisphere. Artistic Ability: The right hemisphere is responsible for the ability to visual arts. Emotions: Although emotions are not a product of the functioning of the right hemisphere, it is associated with them more closely than the left. Sex: The right hemisphere is responsible for sex, unless, of course, you are too concerned with the very technique of this process. Mystic: The right hemisphere is responsible for mysticism and religiosity. Dreams: The right hemisphere is also responsible for dreams. Parallel information processing: The right hemisphere can process a lot of different information at the same time. It is able to consider the problem as a whole without applying analysis. The right hemisphere also recognizes faces, and thanks to it we can perceive a set of features as a whole. Controls the movements of the left half of the body: When you raise your left hand, it means that the command to raise it came from the right hemisphere.

Schematically, this can be represented as follows:

This is, of course, a joke test, but it has some truth. Here is another version of the rotating picture.

After viewing these pictures, the double rotation image is of particular interest.

How else can you check which of the hemispheres you have more developed?

• squeeze your palms in front of you, now interlace your fingers and notice which thumb is on top.
• clap your hands, note which hand is on top.
• cross your arms over your chest, mark which forearm is on top.
• determine the dominant eye.

How can you develop the abilities of the hemispheres.

There are several simple ways to develop the hemispheres. The simplest of them is to increase the volume of work on which the hemisphere is oriented. For example, to develop logic, you need to solve mathematical problems, guess crossword puzzles, and to develop your imagination, visit an art gallery, etc.

The next way is to maximize the use of the side of the body controlled by the hemisphere - for the development of the right hemisphere, you need to work on the left side of the body, and to work out the left hemispheres - on the right. For example, you can draw, jump on one leg, juggle with one hand.

An exercise will help develop the hemisphere, on the awareness of the right and left hemispheres of the brain.

1. Preparation for the exercise.

Sit up straight, close your eyes. Breathing should be calm and even.

Visualize your brain as having two hemispheres and divided into two halves by the corpus callosum. (See picture above) Concentrate on your brain.

We try (in our imagination) to establish a connection with our brain, alternately looking with the left eye into the left hemisphere of the brain, and with the right eye into the right hemisphere. Then, with both eyes, look inward, at the middle of the brain with the corpus callosum.

This will be of interest to you:

2. Performing the exercise.

Slowly inhale, fill with air and hold your breath for a short time. During exhalation, we direct the flow of our consciousness, like a searchlight, to the left hemisphere and "look" at this part of the brain. Then we inhale again, hold our breath and, as we exhale, direct the spotlight to the right hemisphere of the brain.

Imagine: on the left - clear logical thinking; on the right - dream, intuition, inspiration.

Left: inhalation, pause, exhalation is associated with the projection of the number. Right: inhalation, pause, exhalation is associated with the projection of the letter. Those. left: number "1" number "2" number "3", etc. Right: letter "A", letter "B", letter "C", etc.

We continue this combination of numbers and letters until it causes pleasant sensations. Letters and numbers can be swapped, or replaced with something else - for example, summer - winter, white - black. published

The human brain is the main part of the central nervous system, it is located in the cranial cavity. The composition of the brain includes a huge number of neurons, between which there are synaptic connections. These connections allow neurons to form electrical impulses that control the full functioning of the human body.

The human brain is not fully understood. Scientists believe that in a person only a part of neurons are involved in the process of life, and therefore many people do not show their possible abilities.

The left hemisphere of the brain and related functions

The left hemisphere of the brain is responsible for verbal information, it is responsible for the language abilities of a person, controls speech, the ability to write and read. Thanks to the work of the left hemisphere, a person is able to remember various facts, events, dates, names, their sequence and how they will look in writing. The left hemisphere is responsible for the analytical thinking of a person, thanks to this hemisphere, logic and analysis of facts are developed, as well as manipulations with numbers and mathematical formulas. In addition, the left hemisphere of the brain is responsible for the sequence of the information processing process (step-by-step processing).

Thanks to the left hemisphere, all information received by a person is processed, classified, analyzed, the left hemisphere establishes cause-and-effect relationships and formulates conclusions.

The right hemisphere of the brain and its functions

The right hemisphere of the brain is responsible for processing the so-called non-verbal information, that is, for processing information expressed in images and symbols, and not words.

The right hemisphere is responsible for the imagination, with its help a person is able to fantasize, dream, and also compose, learn poetry and prose. Here are located the ability of a person to initiative and art (music, drawing, etc.). The right hemisphere is responsible for parallel processing of information, that is, like a computer, it allows a person to simultaneously analyze several different streams of information, make decisions and solve problems, considering the problem at the same time as a whole and from different angles.

Thanks to the right hemisphere of the brain, we make intuitive connections between images, understand a variety of metaphors, and perceive humor. The right hemisphere allows a person to recognize complex images that cannot be decomposed into elementary components, for example, the process of recognizing people's faces and the emotions that these faces display.

Synchronized work of both hemispheres

The intuitive work of the right hemisphere of the brain is based on facts that have been analyzed by the left hemisphere. It should be noted that the work of both hemispheres of the brain is equally important for a person. With the help of the left hemisphere, the world is simplified and analyzed, and thanks to the right hemisphere, it is perceived as it really is.

If there were no right, "creative" hemisphere of the brain, people would turn into unemotional, calculating machines that could only adapt the world to their life activity.

It should be noted that the right hemisphere controls the work of the left half of the human body, and the left hemisphere - the right half of the body. That is why it is believed that a person who has a better developed left half of the body ("left-handed") has better developed creative abilities. By training the corresponding part of the body, we train the hemisphere of the brain that is responsible for these actions.

In a predominant number of people, one of the hemispheres dominates: the right or the left. When a child is born, he evenly uses the opportunities that he initially has in different hemispheres. However, in the process of development, growth and learning, one of the hemispheres begins to develop more actively. So, in schools where there is a mathematical bias, little time is devoted to creativity, and in art and music schools, children almost do not develop logical thinking.

However, nothing prevents you from training both hemispheres of the brain yourself. So, Leonardo da Vinci, who regularly trained, was fluent in both his right hand and his left. He was not only a creative person, but also an analyst who had excellent logical thinking, and in completely different fields of activity.

The brain is the most important organ that controls the human body. Thanks to its functioning, people are able to see, hear, walk, experience emotions, communicate with each other, feel, analyze, reflect and love. The latter properties are unique to man. Before answering the question of what the left hemisphere of the brain is responsible for, you need to remember the anatomy of grade 9: what the brain consists of.

Structure of the brain

The mass of an organ in an adult is approximately 1400 g. It is located in the cavity of the cranium, covered with shells (soft, hard, arachnoid) on top. There are 3 most significant parts: hemispheres, cerebellum, trunk. The hemispheres of the brain regulate higher nervous activity; they contain departments responsible for vision, hearing, speech, and writing. provides balance, the centers for controlling breathing and heartbeat are laid in the trunk.

Interesting! The brain in men completes its growth by the age of 25, and in women - by 15!

A longitudinal gap passes between the cerebral hemispheres, in the depth of which it is located. The latter connects both hemispheres and allows them to coordinate each other's work. From anatomy lessons, many remember that each of the hemispheres controls the opposite side of the body. From this it follows that the left hemisphere is responsible for the right half of the body.

The brain has 4 lobes (we will talk about them below). Shares are divided by three main furrows: Sylvieva, Rolandova and parietal-occipital. In addition to furrows, the brain has many convolutions.

It is useful to know what it is: forms, possibilities.

Why does a person need: connection with the parts of the brain, the causes of the violation.

The very substance of the brain is divided into gray (bark) and white. Gray is made up of neurons and lines the top of the brain. The thickness of the cortex is about 3 mm, and the number of neurons is about 18 billion. White matter is the pathways (fibers of neurocytes) that occupy the rest of the brain. It is the cortex that controls the whole life of a person from sleep to the manifestation of emotions.

Functions of the left hemisphere of the brain

Large hemispheres are not isolated from other components of the nervous system, they work together with subcortical structures. In addition, with damage to one hemisphere, the other can partially take over the functions of the first, which indicates the joint provision of the work of movements, sensitivity, higher nervous activity and sensory organs.

The cortex is divided into zones responsible for certain functions (vision, hearing, and others), but they do not function separately either. To say something, a person must first think, analyze, calculate. During a conversation, people show emotions (sadness, joy, anxiety, laughter), gesticulate, that is, they use their hands, facial muscles. All this is ensured by the coordinated work of several zones of the cortex, subcortical nuclei, cranial and spinal nerves. So, what are the different parts of the brain responsible for?

Interesting! The human brain is less than half explored!

Frontal lobe of the left hemisphere of the brain

Responsible for movement, ability to speak, personality, thinking. is the part of the brain responsible for emotions, behavior, thinking.

motor cortex

Responsible for the activity of the striated muscles of the right half of the body, coordination of precise movements, orientation in the area. Impulses from internal organs go to this department. When it is damaged, ataxia, paresis of the limbs, a disorder in the work of the heart, blood vessels, and respiration occurs. The picture below shows the topical affiliation of organs and body parts to the precentral gyrus.

Speech motor zone

Provides the work of facial muscles for pronouncing complex words, phrases. In other words, she is responsible for the formation of speech. In all right-handers, the motor speech zone in the left hemisphere occupies a larger area than in the right.

When this zone is destroyed, a person loses the ability to speak, but can scream or sing without words. And also reading to oneself is lost, the formulation of thoughts, but the ability to understand speech does not suffer.

parietal lobe

Here is the zone of sensitivity of the skin, muscles, joints. Impulses from the skin receptors of the arms, legs, torso on the right go to the left hemisphere. If this zone is damaged, there is a violation of sensitivity in some parts of the skin, the ability to determine objects by touch. The sense of touch is lost, the perception of temperature, pain of the right limbs, as well as the trunk on the right, changes.

temporal lobe

The auditory zone is responsible for hearing, vestibular sensitivity. When the zone is destroyed on the left, deafness occurs on the right side, and the ability to hear on the left ear decreases sharply, movements become inaccurate, and staggering occurs when walking (see). Nearby is the auditory speech center, thanks to which people understand the addressed speech and hear their own.

The zone of taste and smell works together with the stomach, intestines, kidneys, bladder, and the reproductive system.

Occipital lobe - visual area

The visual fibers at the base of the brain also intersect, as do the auditory ones. Thus, impulses from both retinas of the eyes go to the visual part of the left hemisphere. Therefore, if this zone is damaged, complete blindness does not occur, but only half of the retina on the left suffers.

The back of the brain is also responsible for the visual center of speech, the ability to recognize written letters and words, so people can read text. The picture shows the parts of the brain responsible for behavior, memory, hearing, touch.

The difference between the left hemisphere and the right

As it has already become clear, in both hemispheres there are speech, visual, auditory and other zones. So what is the difference between them? Is it only in control of opposite halves of the body? Of course not!

Features of the left hemisphere:

1. Logic, analysis, thinking.
2. Numbers, math, calculation.
3. Step by step solution of complex problems.
4. The ability to understand literally.
5. Clear facts, arguments, without unnecessary information.
6. Teaching foreign languages, the ability to control speech.

All about and functions, violations and their consequences.

It is useful to know what it is: a role in the human body, signs of dysfunction.

Everything about: from anatomy to diseases.

What is the right hemisphere of the brain responsible for?

1. Intuition, imagination, emotions.
2. Perception, musicality, artistry.
3. Fantasy, bright colors, the ability to dream.
4. Creating an image according to the description, addiction to mysticism, riddles.

How to determine the dominant hemisphere?

It is said that right-handers have a more developed left hemisphere, while left-handers have the opposite. This is not entirely true. A person can write with his left hand, but be a born mathematician, skeptic, logician and analyst, not at all be fond of painting, music and at the same time not believe in mysticism. It's really hard to tell which hemisphere is dominant, because both of them work when it's needed.

Select rating Poor Okay Good Excellent Excellent

Until recently, it was believed that a person with a developed left hemisphere is much more adapted to real life. And it seems to be clear why. It's easier for him to learn. He is purposeful, can clearly express his desires and describe emotions, and is also able to learn quickly.

This happened because the bulk of the work that was given to people was based on the constant repetition of the same and hard concentration.

Today, the world has changed a little, and dreamers (namely, those who are developed) get a chance to live the way they want. There are many more creative professions. And their thoughtfulness, romanticism and daydreaming are perceived as the ability to think creatively.

Synchronous work of the hemispheres

Despite the fact that each person has more developed either the right or left hemisphere, in fact they work together. It cannot be that only one half of the brain is responsible for all human activity.

Each hemisphere is responsible for certain functions. So, for example, if in general a person did not have the right hemisphere responsible for emotions, then a person would be like a robot without emotions and feelings, which builds life in a way that is beneficial to him. And vice versa, if the left hemisphere did not exist, then the person would turn into a purely antisocial being who cannot take care of himself in any way.

Thanks to both hemispheres, life becomes complete. So, the perception of the world with the help of the left hemisphere is simplified, but the right one makes it native, that is, it shows it as it is, with all the flaws and virtues.

It should also be noted that depending on which hemisphere is more developed, his ability to write will depend, namely, whether a person will be right-handed or left-handed.

It so happened in society that practitioners all know the features of right-handers and left-handers, and therefore, even by character and abilities, they can easily tell which hand he writes with.

Most creative people (actors, writers, etc.) write with their left hand, which once again confirms the theory about the hemispheres.

The functions of the left hemisphere of the brain are very important, as they help a person to analyze information, to perceive the world. In addition, without such abilities, it would be difficult to survive in the current world.

The human brain is the most important and at the same time the least studied organ of the human body.

Let's see what our hemispheres of the brain are responsible for and why some people are mainly left active, while others are right.

What is the left hemisphere of the brain responsible for?

the brain is responsible for verbal information. It controls reading, speech and writing. Thanks to his work, a person can remember a variety of dates, facts and events.

Also The left hemisphere of the brain is responsible for logical thinking. Here, all information received from the outside is processed, analyzed, classified and conclusions are formulated. It processes information analytically and sequentially.

Right By the lusaria of the brain is responsible for processing non-verbal information expressed in images rather than words. Here are the human abilities for various types of creativity, the ability to indulge in dreams, fantasize, compose. It is responsible for generating creative ideas and thoughts.

Also right hemisphere of the brain is responsible for recognition of complex images, such as the faces of people, as well as the emotions displayed on these faces. It processes information simultaneously and holistically.

It should be noted that for a successful human life, coordinated work of both hemispheres is needed.

Which side of your brain is active?

There is a visual, psychophysiological brain hemisphere test(test by Vladimir Pugach), with which you can easily determine which half of your brain is active at a given time. Look at the picture. In which direction is the girl spinning?

If clockwise, it means that at the moment your left hemisphere activity predominates, and if counterclockwise, then right hemisphere activity.

Some may observe the moment of change in the activity of the hemispheres, and then the girl begins to rotate in the opposite direction. This is inherent in people (very few) who simultaneously have left-hemispheric and right-hemispheric brain activity, the so-called ambidexters.

They can achieve the effect of reversing the direction of rotation by tilting their head or by successively focusing and defocusing their vision.

But what about a child's brain?

The most intensive development of the brain occurs in the first years of a child's life. And at this time, the right hemisphere is dominant in children. Since the child learns the world with the help of images, almost all thought processes take place in it.

But we live in a world of logic, in a world with a crazy pace of life, we are in a hurry to do everything, we want more for our children. We try to give them the maximum, we stock up on all sorts of methods of early development and practically from the cradle we begin to teach our children to read, count, we try to give them encyclopedic knowledge, giving early stimulation to the left, and the figurative, intuitive right remains out of work.

And, consequently, when a child grows, matures, the left hemisphere becomes dominant in him, and in the right, due to the lack of stimulation and a decrease in the number of connections between the two halves of the brain, an irreversible decrease in potential occurs.

I want to assure you right away that I do not urge you to let the mental development of your children take its course. Vice versa! Age up to 6 years is the most successful age for the development of brain potential. It's just that development should not be so early, but timely. And if it is laid down by nature that at an early age the right dominates in children, then maybe it is worth developing it, without trying early to stimulate the work of the left with methods aimed at developing logical thinking?

Moreover, the opportunities that our children lose in childhood precisely because of the lack of training of the right hemisphere include truly phenomenal abilities. For example: remembering unlimited amounts of information using images (photographic memory), speed reading, and this is just the beginning of the list of superpowers that your child can have with proper systematic training of the right hemisphere.

I will tell you more about the superpowers that children with a developed right hemisphere have in the next article.

Nadezhda Ryzhkovets

The right and left hemispheres of the brain provide a single work of the body, however, they control opposite sides of the human body, each hemisphere performs its own specific functions and has its own specialization. The work of the right and left hemispheres is asymmetric, but interconnected. What are the left and right hemispheres of our brain responsible for? The left half of the brain is responsible for logical operations, counting, sequencing, and the right hemisphere perceives images, the general content based on intuition, imagination, creativity, the right hemisphere processes facts, details coming from the left hemisphere, collecting them into a single image and a coherent picture. The left hemisphere strives for analysis, logical sequence, details, cause-and-effect relationships. The right hemisphere carries out orientation in space, perception of a holistic picture, captures the image and emotions of human faces.

You can easily test which of the hemispheres of your brain is active at the moment. Look at this picture.

If the girl in the picture rotates clockwise, then at the moment you have more active left hemisphere of the brain (logic, analysis). If it turns counterclockwise, then you have an active right hemisphere (emotions and intuition). It turns out that with some effort of thought, you can make the girl rotate in any direction. of particular interest is the image with double rotation

How else can you check which of the hemispheres you have more developed?

Squeeze your palms in front of you, now interlace your fingers and notice which thumb is on top.

Clap your hands, note which hand is on top.

Cross your arms over your chest, mark which forearm is on top.

Determine the dominant eye.

How can you develop the abilities of the hemispheres.

There are several simple ways to develop the hemispheres. The simplest of them is to increase the volume of work on which the hemisphere is oriented. For example, to develop logic, you need to solve mathematical problems, guess crossword puzzles, and to develop your imagination, visit an art gallery, etc. The next way is to maximize the use of the side of the body controlled by the hemisphere - for the development of the right hemisphere, you need to work on the left side of the body, and to work out the left hemispheres - on the right. For example, you can draw, jump on one leg, juggle with one hand. Exercises will help to develop the hemisphere, on the awareness of the right and left hemispheres of the brain.

ear-nose

With the left hand we take the tip of the nose, and with the right hand - the opposite ear, i.e. left. Release your ear and nose at the same time, clap your hands, change the position of your hands "exactly the opposite."

Mirror drawing

Put a blank sheet of paper on the table, take a pencil. Draw simultaneously with both hands mirror-symmetrical drawings, letters. When doing this exercise, you should feel the relaxation of the eyes and hands, because the simultaneous work of both hemispheres improves the efficiency of the entire brain.

ringlet

We alternately and very quickly go through the fingers, connecting the index, middle, ring, little fingers into a ring with the thumb. First, you can use each hand separately, then simultaneously with both hands.

4. Before you lies a sheet with the letters of the alphabet, almost all of them. The letters L, P or V are written under each letter. The upper letter is pronounced, and the lower one indicates the movement of the hands. L - the left hand rises to the left side, R - the right hand rises to the right side, B - both hands rise up. Everything is very simple, if it were not so difficult to do all this at the same time. The exercise is performed in sequence from the first letter to the last, then from the last letter to the first. The following is written on the sheet.

A B C D E

L P P V L

E F G I K

W L R W L

L M N O P

L P L L P

R S T U V

W R L R W

X C H W I

L W W R L

All the above exercises aimed at developing the right hemisphere can be applied with children.

Visualization exercises .

When you have a free moment, sit the child next to you and offer a little fantasy.

Let's close our eyes and imagine a white sheet of paper on which your name is written in large letters. Imagine that the letters have become blue... And now they are red, and now they are green. Let them be green, but the sheet of paper suddenly turned pink, and now it is yellow.

Now listen, someone is calling your name. Guess whose voice it is, but don't tell anyone, sit quietly. Imagine that someone is humming your name, and music is playing around. Let's listen!

And now we'll touch your name. What does it feel like? Soft? Rough? Warm? Fluffy? All have different names.

Now we will taste your name. Is it sweet? Or maybe sour? Cold like ice cream or warm?

We learned that our name can have a color, a taste, a smell, and even be something to the touch.

Now let's open our eyes. But the game isn't over yet.

Ask the child to tell about his name, about what he saw, heard and felt. Help him a little, remind him of the task and be sure to encourage: “How interesting!”, “Wow!”, “I would never have thought that you have such a wonderful name!”.

The story is over. We take pencils and ask to draw a name. The child can draw whatever he wants, the main thing is that the drawing reflects the image of the name. Let the child decorate the drawing, use as many colors as possible. But don't drag this out. It is important to finish drawing at a strictly defined time. At this point, you yourself think about how much to allocate for drawing - a slow kid needs twenty minutes, and a hasty one will draw everything in five minutes.

The drawing is ready. Let the kid explain what these or those details mean, what he tried to draw. If it is difficult for him to do this, help: "What is this drawn? And this? Why did you draw this particular one?"

Now the game is over, you can rest.

You probably guessed what its essence is. We led the child through all the senses: vision, taste, smell, forced him to engage in activity and imagination, and speech. Thus, all areas of the brain had to take part in the game.

Now you can come up with other games built on the same principle. For example: " flower name"- draw a flower that we could call our own name; " I am an adult"- we try to imagine and draw ourselves as adults (how I will be dressed, how I say what I do, how I walk, and so on); " imaginary gift "- let the kid give imaginary gifts to his friends, and tell you how they look, smell, what they feel like.

You are stuck in a traffic jam, you are on a train for a long time, you are bored at home or waiting in line for a doctor - play the suggested games. The kid is delighted and does not whine: "I'm bored, well, when will it finally ...", and the parent's heart rejoices - the child is developing!

We offer you another visualization exercise called " Erasure from memory of stressful information ".

Have your child sit down, relax, and close their eyes. Let him imagine a blank album sheet, pencils, an eraser in front of him. Now invite the child to mentally draw on the sheet a negative situation that needs to be forgotten. Next, ask, again mentally, to take an eraser and begin to consistently erase the situation. You need to erase until the picture disappears from the sheet. After that, you should open your eyes and check: close your eyes and imagine the same sheet of paper - if the picture has not disappeared, you need to mentally take the eraser again and erase the picture until it disappears completely. Exercise is recommended to be repeated periodically.

By the way, when you do something with both hands at the same time, such as playing a musical instrument or even typing on a keyboard, both hemispheres work. So this is also a kind of training. It is also useful to perform habitual actions not with the leading hand, but with the other. Those. right-handers can live the life of left-handers, and left-handers, respectively, on the contrary, become right-handers. For example, if you usually brush your teeth holding the brush in your left hand, then periodically shift it to your right. If you write with your right hand, shift your pen to your left. This is not only useful, but also fun. And the results of such training will not be long in coming.

5. Looking at the picture, you need to say out loud as quickly as possible the colors with which the words are written.

This is how you can harmonize the work of the hemispheres of the brain.

The brain is the most important organ that controls the human body. Thanks to its functioning, people are able to see, hear, walk, experience emotions, communicate with each other, feel, analyze, reflect and love. The latter properties are unique to man. Before answering the question of what the left hemisphere of the brain is responsible for, you need to remember the anatomy of grade 9: what the brain consists of.

Structure of the brain

The mass of an organ in an adult is approximately 1400 g. It is located in the cavity of the cranium, covered with shells (soft, hard, arachnoid) on top. There are 3 most significant parts: hemispheres, cerebellum, trunk. The hemispheres of the brain regulate higher nervous activity; they contain departments responsible for vision, hearing, speech, and writing. provides balance, the centers for controlling breathing and heartbeat are laid in the trunk.

Interesting! The brain in men completes its growth by the age of 25, and in women - by 15!

Between there is a longitudinal slit, in the depth of which it is located. The latter connects both hemispheres and allows them to coordinate each other's work. From anatomy lessons, many remember that each of the hemispheres controls the opposite side of the body. From this it follows that the left hemisphere is responsible for the right half of the body.

The brain has 4 lobes (we will talk about them below). Shares are divided by three main furrows: Sylvieva, Rolandova and parietal-occipital. In addition to furrows, the brain has many convolutions.

It is useful to know what it is: forms, possibilities.

Why does a person need: connection with the brain, the causes of the violation.

The very substance of the brain is divided into gray (bark) and white. Gray is made up of neurons and lines the top of the brain. The thickness of the cortex is about 3 mm, and the number of neurons is about 18 billion. White matter is the pathways (fibers of neurocytes) that occupy the rest of the brain.

Large hemispheres are not separated from other components of the nervous system, they work together with subcortical structures. In addition, with damage to one hemisphere, the other can partially take over the functions of the first, which indicates the joint provision of the work of movements, sensitivity, higher nervous activity and sensory organs.

The cortex is divided into zones responsible for certain functions (vision, hearing, and others), but they do not function separately either. To say something, a person must first think, analyze, calculate. During a conversation, people show emotions (sadness, joy, anxiety, laughter), gesticulate, that is, they use their hands, facial muscles. All this is ensured by the coordinated work of several zones of the cortex, subcortical nuclei, cranial and spinal nerves. So, what are the different parts of the brain responsible for?

Interesting! The human brain is less than half explored!

Frontal lobe of the left hemisphere of the brain

Responsible for movement, ability to speak, personality, thinking. is the part of the brain responsible for emotions, behavior, thinking.

motor cortex

Responsible for the activity of the striated muscles of the right half of the body, coordination of precise movements, orientation in the area. Impulses from the internal organs go to this department. When it is damaged, ataxia, paresis of the limbs, a disorder in the work of the heart, blood vessels, and respiration occurs. The picture below shows the topical affiliation of organs and body parts to the precentral gyrus.

Speech motor zone

Provides the work of facial muscles for pronouncing complex words, phrases. In other words, she is responsible for the formation of speech. In all right-handers, the motor speech zone in the left hemisphere occupies a larger area than in the right.

When this zone is destroyed, a person loses the ability to speak, but can scream or sing without words. And also reading to oneself is lost, the formulation of thoughts, but the ability to understand speech does not suffer.

parietal lobe

Here is the zone of sensitivity of the skin, muscles, joints. Impulses from the skin receptors of the arms, legs, torso on the right go to the left hemisphere. If this zone is damaged, there is a violation of sensitivity in some parts of the skin, the ability to determine objects by touch. The sense of touch is lost, the perception of temperature, pain of the right limbs, as well as the trunk on the right, changes.

temporal lobe

The auditory zone is responsible for hearing, vestibular sensitivity. When the zone is destroyed on the left, deafness occurs on the right side, and the ability to hear on the left ear is sharply reduced, movements become inaccurate, and staggering occurs when walking (see). Nearby is the auditory speech center, thanks to which people understand the addressed speech and hear their own.

The zone of taste and smell works together with the stomach, intestines, kidneys, bladder, and the reproductive system.

Occipital lobe - visual area

The visual fibers at the base of the brain also intersect, as do the auditory ones. Thus, impulses from both retinas of the eyes go to the visual part of the left hemisphere. Therefore, if this zone is damaged, complete blindness does not occur, but only half of the retina on the left suffers.

The back of the brain is also responsible for the visual center of speech, the ability to recognize written letters and words, so people can read text. The picture shows the parts of the brain responsible for behavior, memory, hearing, touch.

The difference between the left hemisphere and the right

As it has already become clear, in both hemispheres there are speech, visual, auditory and other zones. So what is the difference between them? Is it only in control of opposite halves of the body? Of course not!

Features of the left hemisphere:

1. Logic, analysis, thinking.
2. Numbers, math, calculation.
3. Step by step solution of complex problems.
4. The ability to understand literally.
5. Clear facts, arguments, without unnecessary information.
6. Teaching foreign languages, the ability to control speech.

All about and functions, violations and their consequences.

It is useful to know what it is: role in the human body, signs of dysfunction.

Everything about: from anatomy to diseases.

What is the right hemisphere of the brain responsible for?

1. Intuition, imagination, emotions.
2. Perception, musicality, artistry.
3. Fantasy, bright colors, the ability to dream.
4. Creating an image according to the description, addiction to mysticism, riddles.

How to determine the dominant hemisphere?

It is said that right-handers have a more developed left hemisphere, while left-handers have the opposite. This is not entirely true. A person can write with his left hand, but be a born mathematician, skeptic, logician and analyst, not at all be fond of painting, music and at the same time not believe in mysticism. It's really hard to tell which hemisphere is dominant, because both of them work when it's needed.

The human brain is the most inaccessible and difficult to study. Even in the era of the introduction of new modern methods of research, the brain has not been fully understood. The brain is divided into 2 halves of the hemisphere, each of which is responsible for its own group of functions.

There are many proven facts about the brain, here are some of them:

• The number of neurons (nerve cells) reaches 85 billion
• The mass of the brain of an adult is on average about 1.4 kg, that is, about 2 - 3% of the total mass of a person.
• The size of the brain does not affect mental ability in any way, which has been proven in recent studies.

In this article, we will take a detailed look at the structure and function of each of the hemispheres and conduct a test that will establish which of the hemispheres is dominant.

Functions of the left hemisphere in the following directions:

• Ability to perceive verbal (oral) speech
• Ability to learn languages. You can meet quite a lot of people who know 3, 4 or more languages, while it was not difficult to learn from them. The reason for memorizing new languages ​​lies in the high development of the left hemisphere
• The predisposition to good language memorability lies with our memory, which also allows us to remember dates, numbers, events, etc. As a rule, with a good memory and a consequently developed hemisphere, people become analysts, teachers, etc. Some people, so to speak, with high abilities, able to point to the exact page where a certain text is located
• Development of speech functionality. Consequently, the stronger the left side prevails, the faster the child begins to speak, while maintaining the correct construction of speech.
• Performs sequential (logical) processing of information
• Predisposition to heightened perception of reality. That is, for example, red remains red, blue, blue, while the use of metaphorical phrases is not characteristic of a person
• The ability to establish cause-and-effect relationships based on logical beliefs, that is, a person is predisposed to the fact that each receipt of information is compared and has a logical connection, this is especially characteristic of the profession of an operative
• Controls the right side of the body

The left hemisphere is characterized by a more explosive nature of a person and the management of the search and acquisition of new information.

Right Hemisphere Functions

It has also historically developed, over a long period, that this part of the brain acted as an outcast. Many scientists have argued that this hemisphere is of no use to humans and is a "dead" and unnecessary part of our brain. It got to the point that some surgeons simply removed the hemisphere, referring to its uselessness.

Gradually, the importance of the right side increased and at the moment it occupies the same strong position as the left section. The functions it performs are expressed as follows:

• The predominance of the development of non-verbal and holistic representation, that is, the information received is expressed not verbally, but by symbols or some images
• It is characterized by visual-spatial perception. Thanks to this ability, a person has the ability to navigate the terrain
• Emotionality. Although this function is not directly related to the hemispheres, the development of the right side still has a somewhat significant effect than the left.
• Perception of metaphors. That is, if a person expressed himself in some kind of metaphor, another person with a developed mind will easily understand what is being said.
• Creative inclination. It is the individuals with the predominant development of this part that in most cases become musicians, writers, etc.
• Parallel information processing. The right hemisphere has the ability to process various data sources. The incoming information is not processed on the basis of a logical sequence, but is presented as a whole
• Controls the motor abilities of the left side of the body

Research on the function of the cerebral hemispheres of her right side shows that it is also responsible for reducing the negative reaction to stressful situations, emotions and tries to avoid something unknown.

Dominant hemisphere test

This test will reveal a stronger development of the right or left side of the brain, after several consecutive exercises. Try the following:

1. Exercise #1

Bring your palms together in front of you and cross your fingers. Look at your thumbs and write down on a piece of paper which of the fingers is higher.

1. Exercise #2

Take a piece of paper and drill a small hole in the center, but it should be enough so that when you look through this hole you can see the whole environment. First, look through it with both eyes. Then, in turn, look with each eye, while when we look at one eye, the other should be covered.

You should be careful when viewing through the hole, as when examining a thing, it will shift somewhat. Write down on a piece of paper in which eye you had a shift.

1. Exercise #3

Cross your arms over your chest and write down on a piece of paper, turned out to be higher.

1. Exercise number 4

Clap your hands a couple of times and write down on a piece of paper which of the hands turned out to be dominant, that is, which palm covers the other.

Now is the time to check the results. For each exercise, you had to choose the dominant hand R - right hand, L - left hand. Then compare with the results below:

• PPPP - this indicates that you rather have no desire to change anything, that is, there are certain stereotypes that you follow
• PPPL - lack of decisiveness in any issue and action
• PPLP - high communication skills and artistry
• PPLL - decisive character, but at the same time there is softness towards others
• PPP - a predisposition to analytics, high caution when making any decisions
• PLPL - there is exposure to other people's opinions, you are easily manipulated
• LPPP - very high emotionality

Conclusion

Even though in most cases people have a more developed right hemisphere than the left, in fact, their work is always interconnected. In reality, it cannot be that only one part of the brain functions in a person, and the second does not perform any functions.

Each part is responsible for its specific aspects of activity. Even if you look at what would happen if the right hemisphere, which is responsible for our emotionality, was absent. In this case, a person could be compared to a computer that performs a certain number of logical functions, but does not experience emotionality.

The absence of the left, respectively, would lead to a complete loss of socialization. It is precisely due to the fact that the functions of the hemispheres of the human brain work interrelatedly that our life seems to be a complete picture with logical, emotional and other equally important components.

The right and left hemispheres of the brain provide a single work of the body, however, they control opposite sides of the human body, each hemisphere performs its own specific functions and has its own specialization. The work of the right and left hemispheres is asymmetric, but interconnected. What are the left and right hemispheres of our brain responsible for? The left half of the brain is responsible for logical operations, counting, sequencing, and the right hemisphere perceives images, the general content based on intuition, imagination, creativity, the right hemisphere processes facts, details coming from the left hemisphere, collecting them into a single image and a coherent picture. The left hemisphere strives for analysis, logical sequence, details, cause-and-effect relationships. The right hemisphere carries out orientation in space, perception of a holistic picture, captures the image and emotions of human faces.

You can easily test which of the hemispheres of your brain is active at the moment. Look at this picture.

If the girl in the picture rotates clockwise, then at the moment you have more active left hemisphere of the brain (logic, analysis). If it turns counterclockwise, then you have an active right hemisphere (emotions and intuition). It turns out that with some effort of thought, you can make the girl rotate in any direction. of particular interest is the image with double rotation

How else can you check which of the hemispheres you have more developed?

Squeeze your palms in front of you, now interlace your fingers and notice which thumb is on top.

Clap your hands, note which hand is on top.

Cross your arms over your chest, mark which forearm is on top.

Determine the dominant eye.

How can you develop the abilities of the hemispheres.

There are several simple ways to develop the hemispheres. The simplest of them is to increase the volume of work on which the hemisphere is oriented. For example, to develop logic, you need to solve mathematical problems, guess crossword puzzles, and to develop your imagination, visit an art gallery, etc. The next way is to maximize the use of the side of the body controlled by the hemisphere - for the development of the right hemisphere, you need to work on the left side of the body, and to work out the left hemispheres - on the right. For example, you can draw, jump on one leg, juggle with one hand. Exercises will help to develop the hemisphere, on the awareness of the right and left hemispheres of the brain.

ear-nose

With the left hand we take the tip of the nose, and with the right hand - the opposite ear, i.e. left. Release your ear and nose at the same time, clap your hands, change the position of your hands "exactly the opposite."

Mirror drawing

Put a blank sheet of paper on the table, take a pencil. Draw simultaneously with both hands mirror-symmetrical drawings, letters. When doing this exercise, you should feel the relaxation of the eyes and hands, because the simultaneous work of both hemispheres improves the efficiency of the entire brain.

ringlet

We alternately and very quickly go through the fingers, connecting the index, middle, ring, little fingers into a ring with the thumb. First, you can use each hand separately, then simultaneously with both hands.

4. Before you lies a sheet with the letters of the alphabet, almost all of them. The letters L, P or V are written under each letter. The upper letter is pronounced, and the lower one indicates the movement of the hands. L - the left hand rises to the left side, R - the right hand rises to the right side, B - both hands rise up. Everything is very simple, if it were not so difficult to do all this at the same time. The exercise is performed in sequence from the first letter to the last, then from the last letter to the first. The following is written on the sheet.

A B C D E

L P P V L

E F G I K

W L R W L

L M N O P

L P L L P

R S T U V

W R L R W

X C H W I

L W W R L

All the above exercises aimed at developing the right hemisphere can be applied with children.

Visualization exercises .

When you have a free moment, sit the child next to you and offer a little fantasy.

Let's close our eyes and imagine a white sheet of paper on which your name is written in large letters. Imagine that the letters have become blue... And now they are red, and now they are green. Let them be green, but the sheet of paper suddenly turned pink, and now it is yellow.

Now listen, someone is calling your name. Guess whose voice it is, but don't tell anyone, sit quietly. Imagine that someone is humming your name, and music is playing around. Let's listen!

And now we'll touch your name. What does it feel like? Soft? Rough? Warm? Fluffy? All have different names.

Now we will taste your name. Is it sweet? Or maybe sour? Cold like ice cream or warm?

We learned that our name can have a color, a taste, a smell, and even be something to the touch.

Now let's open our eyes. But the game isn't over yet.

Ask the child to tell about his name, about what he saw, heard and felt. Help him a little, remind him of the task and be sure to encourage: “How interesting!”, “Wow!”, “I would never have thought that you have such a wonderful name!”.

The story is over. We take pencils and ask to draw a name. The child can draw whatever he wants, the main thing is that the drawing reflects the image of the name. Let the child decorate the drawing, use as many colors as possible. But don't drag this out. It is important to finish drawing at a strictly defined time. At this point, you yourself think about how much to allocate for drawing - a slow kid needs twenty minutes, and a hasty one will draw everything in five minutes.

The drawing is ready. Let the kid explain what these or those details mean, what he tried to draw. If it is difficult for him to do this, help: "What is this drawn? And this? Why did you draw this particular one?"

Now the game is over, you can rest.

You probably guessed what its essence is. We led the child through all the senses: vision, taste, smell, forced him to engage in activity and imagination, and speech. Thus, all areas of the brain had to take part in the game.

Now you can come up with other games built on the same principle. For example: " flower name"- draw a flower that we could call our own name; " I am an adult"- we try to imagine and draw ourselves as adults (how I will be dressed, how I say what I do, how I walk, and so on); " imaginary gift "- let the kid give imaginary gifts to his friends, and tell you how they look, smell, what they feel like.

You are stuck in a traffic jam, you are on a train for a long time, you are bored at home or waiting in line for a doctor - play the suggested games. The kid is delighted and does not whine: "I'm bored, well, when will it finally ...", and the parent's heart rejoices - the child is developing!

We offer you another visualization exercise called " Erasure from memory of stressful information ".

Have your child sit down, relax, and close their eyes. Let him imagine a blank album sheet, pencils, an eraser in front of him. Now invite the child to mentally draw on the sheet a negative situation that needs to be forgotten. Next, ask, again mentally, to take an eraser and begin to consistently erase the situation. You need to erase until the picture disappears from the sheet. After that, you should open your eyes and check: close your eyes and imagine the same sheet of paper - if the picture has not disappeared, you need to mentally take the eraser again and erase the picture until it disappears completely. Exercise is recommended to be repeated periodically.

By the way, when you do something with both hands at the same time, such as playing a musical instrument or even typing on a keyboard, both hemispheres work. So this is also a kind of training. It is also useful to perform habitual actions not with the leading hand, but with the other. Those. right-handers can live the life of left-handers, and left-handers, respectively, on the contrary, become right-handers. For example, if you usually brush your teeth holding the brush in your left hand, then periodically shift it to your right. If you write with your right hand, shift your pen to your left. This is not only useful, but also fun. And the results of such training will not be long in coming.

5. Looking at the picture, you need to say out loud as quickly as possible the colors with which the words are written.

This is how you can harmonize the work of the hemispheres of the brain.
