The main functions of the right hemisphere of the brain and exercises for its development. What is the left hemisphere of the human brain responsible for?

The structure of the human brain is quite complex, but every schoolchild knows that there are right and left hemispheres. The specialization of the cerebral hemispheres is the most interesting object of joint study by physicians and psychologists, and a lot of discoveries have already been made in this area.

Science determines psyche human being as a property of highly organized matter, expressed in the form of a subjective reflection of objective reality.

Highly organized matter is human brain, which processes information coming from the senses, controls emotions, feelings and behavior, organizes all mental processes and states.

Although the anatomy and physiology of the brain is quite complex, it is a well-known fact that the cerebral cortex is divided into two hemispheres.

Depending on what function the brain performs at a given, specific moment, one of the hemispheres becomes more active. The hemisphere that is most often involved in brain function is considered dominant.

For a long time, only the left hemisphere was identified as dominant in all people. It is now recognized that the right hemisphere can be dominant, and both of these parts of the brain can be developed equally.

Spheres of influence of the cerebral hemispheres

The main functions of the left hemisphere are logical thinking and speech. The left hemisphere is focused on working with numbers and letters.

The left hemisphere determines the following human abilities:

The main functions of the right hemisphere are imaginative thinking and intuition. The right hemisphere focuses on images and emotions.

The right hemisphere determines the following human abilities:

figurative perception and processing of all information at once, in its entirety, the ability to perceive the totality of something as a single image;
processing of non-verbal signals: understanding of non-verbal information coming in the form of images and symbols, body signals both from outside and from inside the human body;
orientation in space: the ability to determine one’s location and the position of objects in space;
creative abilities: music, drawing, poetry and others;
understanding the meaning of words and metaphors;
imagination: the ability to imagine, dream, fantasize and understand the results of another person’s imagination;
emotional perception (although another part of the brain is responsible for the emotional sphere of a person, the right hemisphere connects it to the process of perceiving the world);
the ability to perceive and believe in irrational phenomena.

Artist or thinker

Depending on which hemisphere is predominantly dominant, there are two personality types:

Thinker, a person with a technical mindset is a left-hemisphere type.
Artist, a person with a humanitarian mindset is a right-hemisphere type.

How to determine the dominant hemisphere? There are several methods, the simplest and most popular is the “Leading Hemisphere of the Brain” test.

To determine the dominant hemisphere you need:

Bring your hands together, interlocking your fingers. Look and write down on paper the thumb of which hand is on top.
Make a small hole in a sheet of paper (you can use a pencil), and look through it with both eyes at any object. Then alternately close your left and right eyes. Please note that the object moves when the right or left eye is closed. Record your answer on a piece of paper.
Cross your arms over your chest so that your palms are on your forearms. Mark which hand is on top.
Clap your hands. Write down which palm is on top.

If there are more answers “right hand” - a right-hemisphere type, “left hand” - a left-hemisphere type.

An interesting fact is that the right hemisphere of the brain controls the left half of the body, sending signals there in the form of electrical impulses, and the left hemisphere controls the right side of the human body.

For normal functioning, a person must have sufficiently developed both hemispheres of the brain. Physical and physiological damage is often irreversible and leads to severe illness. Such a phenomenon as degradation can also cause considerable harm to the brain.

Self-improvement is the basis for the development of personality and the human brain.

To achieve balance in the psyche, to become a more harmoniously developed personality, you need use both hemispheres of the brain:

Work on those areas, with that part of the brain that is less developed. To do this, it is enough just to increase the load on the less developed hemisphere. For example, an Artist should start solving logical riddles, a Thinker should start looking at paintings by abstract artists.
Physical development of that part of the body that is controlled by the less developed hemisphere. For example, a right-handed person should try to learn to draw with his left hand in order to develop a right-hemisphere type of thinking.

The abilities of the brain are limitless and have not been fully studied; working on yourself allows you to look into this infinity, full of potential.

Cerebral hemispheres

The brain controls all activities of the central nervous system. Until now, it has been poorly studied and is fraught with many mysteries for scientists. Many of us know from our school biology course that our brain has two hemispheres, each of which performs its own functions. Next, we will look at what exactly they are responsible for, and will dwell in more detail on the right hemisphere of the brain.

Let's start by looking at what the left hemisphere is responsible for. The left hemisphere of the brain is responsible for things related to logic. His activities are related to verbal communication, memory, handling numbers, facts, and abstract thinking. When processing experience, it analyzes, classifies, systematizes what happened and, on the basis of this, makes a general conclusion. The left side of the brain is a good helper where analytical thinking is required, you need to establish the cause of an event and its consequence. It allows you to engage in activities in stages, gradually moving from one point of the plan to another. Thanks to it, we perceive the meaning of what is said literally. People with a developed left hemisphere have a good ability for languages and usually know several foreign languages. The left hemisphere controls the right half of the body.

Functions of the right hemisphere

Below we will look at what the right hemisphere of our brain is responsible for.

Useful to know: The medulla oblongata, what functions it is responsible for and what diseases it suffers from

The principle of how the hemispheres of the brain work is especially noticeable when observing a person who has had one of them removed. People who have had the right half of their brain removed have difficulty navigating even a small area and need help to get to their destination. Such a person takes everything said literally, because... cannot perceive the allegorical meaning of words. He does not react to other people's emotions and appears unemotional himself. He cannot enjoy music. However, the regenerative abilities of our body are such that subsequently the remaining half takes on part of the functions of the removed one. This is especially true in cases where the operation was performed in childhood.

What will the development of the right hemisphere give us?

Drawing a general conclusion, we note that the activity of the left side of the brain is associated with processing previous experience and generating decisions based on it. However, we all know that it is impossible to create something new, guided only by previous experience. The right half of the brain goes beyond experience, creates something that did not exist. It gives us a holistic perception of information, rather than getting bogged down in details. Taking a holistic view of a problem allows us to create a solution that would not be possible if we focused only on part of it.

I am glad to welcome you, dear readers of my blog! As promised in the previous article, today we will look at what the right hemisphere of the brain is responsible for. I also want to offer an integrated approach to develop both halves. Then you will be successful in any activity, and also learn how to masterfully control your hands, and perform various functions at the same time.

Functions

The right hemisphere is responsible for our creative part, that is, the ability to fantasize, process information that comes in the form of images and symbols.

Helps to recognize the non-verbal manifestations of a person, which, as you know, are very important in the communication process, since body signals are true and truthful. It is thanks to this part of the brain that we can consider a situation from different angles, give an objective assessment and, in general, capture many nuances at the same time, managing to process and systematize them.

A person who has more developed logic does not understand jokes and takes everything literally. On the contrary, a creative person in this regard is very plastic, thinking using metaphors. She is able to write poetry, music, draw and understand people well, because she is intuitive and sensitive. He knows the terrain well, again thanks to the ability to take an unconventional approach to solving problems, putting puzzles together into one picture in his imagination.

Of course, if you raise your left arm or leg up, this means that the opposite hemisphere is involved in the work, since the left side of your body is subordinate to it. It is generally accepted that the orientation of a person with a dominant right half is directed towards the environment, that is, outward and is called extraversion.

He is more sociable, subject to emotions and momentary impulses. It does not act according to a clear plan, but based on the situation, adapting to changing conditions. To find out which half is more developed for you, you can experiment by completing the tasks set out about the left hemisphere of the brain.

Exercises

So, in order to improve your creative side, you should visit exhibitions, museums, art galleries, and, of course, try yourself in writing poems, stories, and practice drawing, even if it’s abstract and understandable only to you. Dancing helps coordinate movements, which also has a beneficial effect on development.
Start practicing visualization techniques that will help you achieve your goals faster and also help you develop your ability to fantasize and daydream. It’s easy to do, just study it first, where I talk in detail about all the nuances of the practice.
Meditation is not easy for people who have well-developed logical thinking, but it is very effective for them. And not only to expand the boundaries of consciousness, the ability to move away from a clear structure and think three-dimensionally, but also to improve the quality of life and health. Start with a very simple meditation focused on breathing and concentration. You will find detailed instructions.
Massage your left ear to help activate the right side of your brain. Suitable in cases where it is necessary to take a creative approach to solving any issue and rely on your intuition.
Creativity is not limited to drawing and poetry, read jokes and watch humorous programs, laughter will not only activate the brain, but also improve well-being, preventing the onset of depression. Besides, are you aware that people who use humor and sarcasm in their speech have a high level of intelligence?
When listening to music, try to listen to your feelings and breathing. Let images, associations and pictures circle freely in your head, do not control them, trying to get rid of them. Just watch them, like an unwitting spectator of a performance organized by your consciousness and subconscious.

An integrated approach to the development of both halves of the brain

As I already said, it is important to coordinate the work of both halves in order to expand their capabilities and functions for which they are responsible. Then you will be provided with a creative approach to solving even the most complex problems, and the speed and efficiency of information processing will also increase.

Sit comfortably with a straight back, choose a point in front of you, you will have to concentrate on it. After about a minute, try using your peripheral vision, without taking your eyes off the selected point, to see what is to your left, and then to your right.
With one hand, stroke your stomach, and with the other, perform tapping movements on your head. Slowly at first to adjust, building up the pace over time.
Also, the development of both hemispheres will provide you with the following task: place the finger of one hand on the tip of your nose, and with the other hand grab the ear opposite to it. For example, the right hand should take the left ear. As soon as you take it, clap your hands and do the same, changing the position of your hands. That is, the fingers of a completely different hand touch the nose, exactly the same pattern with the ears.
Stretch your arms in front of you, draw a square in the air with one of them, for example, and a circle with the other. When you feel that you have made progress, come up with new figures to master.

Conclusion

Do the exercises, and over time you will notice how easier it has become to make decisions and do your usual work, communicate with people, and so on. You can periodically check your intelligence level to see how much it increases and changes. You can learn more about this from the article

Our brain is a mystery, but on the pages of this blog, I will collect information about all the possible ways to develop it. Subscribe to updates so as not to miss the release of new articles. Bye bye.

Until recently, it was believed that a person with a developed left hemisphere is much more adapted to real life. And it seems clear why. It's easier for him to learn. He is goal-oriented, 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 constant repetition of the same tasks and rigid concentration.

Today, the world has changed a little, and people who are dreamers (that’s what they call those who are highly developed) get a chance to live the way they want. Many more creative professions are emerging. And their thoughtfulness, romanticism and dreaminess are perceived as the ability to think creatively.

Synchronous operation of the hemispheres

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

Each hemisphere is responsible for certain functions. So, for example, if a person did not have a right hemisphere responsible for emotions, then the person would be like a robot without emotions and feelings, who builds life in a way that is beneficial to him. And vice versa, if there were no left hemisphere, then a person would turn into a purely asocial being who could not take care of himself.

Thanks to both hemispheres, life becomes full. Thus, the perception of the world with the help of the left hemisphere is simplified, but the right hemisphere makes it familiar, that is, shows it as it is, with all its flaws and advantages.

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

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

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

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

The human brain is the most important and yet least studied organ of the human body.

Let's figure out what our brain hemispheres are responsible for and why some people have mainly the left one active, while others have the right one.

What is the left hemisphere of the brain responsible for?

the brain is responsible for verbal information. It controls reading, speaking and writing. Thanks to its 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 outside is processed, analyzed, classified and conclusions are formulated. It processes information analytically and sequentially.

Right By the hemisphere of the brain is responsible for processing nonverbal information expressed in images rather than words. This is also where a person’s abilities for various types of creativity are located, the ability to indulge in dreams, fantasize, and 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 people's faces, as well as the emotions displayed on these faces. It processes information simultaneously and holistically.

It should be noted that for a person to live a successful life, the coordinated work of both hemispheres is necessary.

Which hemisphere of your brain is active?

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

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

Some may observe the moment when the activity of the hemispheres changes, and then the girl begins to rotate in the opposite direction. This is characteristic of people (very few) who simultaneously have left-hemisphere and right-hemisphere brain activity, the so-called ambidextrous people.

They can achieve the effect of changing the direction of rotation by tilting the head or sequentially concentrating and defocusing their vision.

What about the 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 a child learns about the world through images, almost all mental processes occur in him.

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 early development methods and practically from the cradle we begin to teach our children reading and counting, we try to give them encyclopedic knowledge, giving early stimulation to the left, while the imaginative, intuitive right remains, as it were, out of work.

And, therefore, when a child grows and matures, the left hemisphere becomes dominant, 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 leave the mental development of your children to chance. Vice versa! The age of up to 6 years is the most favorable age for developing brain potential. It’s just that development should not be so early as it should be timely. And if it is inherent in nature that the right dominates in children at an early age, then maybe it is worth developing it, without trying to early 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: memorizing unlimited amounts of information using images (photographic memory), speed reading, and this is only 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 ensure the unified functioning of the body, but 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 asymmetrical, 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, establishing a sequence, and the right hemisphere perceives images, 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 holistic picture. The left hemisphere strives for analysis, logical sequence, details, cause-and-effect relationships. The right hemisphere provides orientation in space, perception of the whole picture, and records the image and emotions of human faces.

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

If the girl in the picture is rotating clockwise, then at the moment your left hemisphere of the brain is more active (logic, analysis). If it turns counterclockwise, then your right hemisphere is active (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 hemisphere is more developed?

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

Clap your hands and mark which hand is on top.

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

Determine your 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 an increase in the amount of work on which the hemisphere is oriented. For example, to develop logic, you need to solve mathematical problems, solve crosswords, and to develop imagination, visit an art gallery, etc. The next way is to maximally use the side of the body controlled by the hemisphere - to develop the right hemisphere, you need to work with the left part of the body, and to work out the left hemisphere, you need to work with the right. For example, you can draw, jump on one leg, juggle with one hand. Exercises for awareness of the right and left hemispheres of the brain will help develop the hemisphere.

Ear-nose

With our left hand we take the tip of the nose, and with our right hand we take the opposite ear, i.e. left. At the same time, release your ear and nose, clap your hands, change the position of your hands “exactly the opposite.”

Mirror drawing

Place a blank sheet of paper on the table and take a pencil. Draw mirror-symmetrical designs and letters with both hands at the same time. When doing this exercise, you should feel your eyes and hands relax, because when both hemispheres work simultaneously, the efficiency of the entire brain improves.

ring

We move our fingers one by one and very quickly, connecting the index, middle, ring, and little fingers into a ring with the thumb. First, you can do it with each hand separately, then with both hands simultaneously.

4. In front of you lies a piece of paper with the letters of the alphabet, almost all of them. Under each letter the letters L, P or V are written. The upper letter is pronounced, and the lower letter indicates movement with the hands. L - left hand rises to the left, R - right hand rises to right side, B - both hands rise up. Everything is very simple, if only it weren’t so difficult to do it all 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 piece of paper.

A B C D E

L P P V L

E F Z I K

V L R V L

L M N O P

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

Visualization exercises .

When you have a free minute, sit your child next to you and invite them to dream up a little.

Let's close our eyes and imagine a white sheet of paper with your name written in big letters. Imagine that the letters became blue... And now they are red, and now they are green. They may be green, but the sheet of paper suddenly turned pink, and now yellow.

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

Now we will touch your name. What does it feel like? Soft? Rough? Warm? Fluffy? Everyone's names are different.

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

We learned that our name can have a color, a taste, a smell, and even feel something.

Now let's open our eyes. But the game is not over yet.

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

The story is over. We take pencils and ask them to draw a name. A child can draw whatever he wants, as long as the drawing reflects the image of the name. Let the child decorate the drawing and use as many colors as possible. But don't delay this activity. It is important to finish drawing at a strictly defined time. At this point, you decide for yourself how much time to spend on drawing - a slow kid needs about twenty minutes, but a hurry-up kid will draw everything in five minutes.

The drawing is ready. Let the child explain what certain details mean and what he tried to draw. If it’s difficult for him to do this, help him: “What is this drawn? And this? Why did you draw exactly this?”

Now the game is over, you can rest.

You probably guessed what its essence is. We took the child through all his senses: sight, taste, smell, and forced him to engage in activities, both 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 by its name; " I'm an adult" - we try to imagine and draw ourselves as an adult (how I will dress, how I speak, what I do, how I walk, and so on); " Imaginary gift " - let the baby give imaginary gifts to his friends, and tell you what they look like, smell, and feel like.

You are stuck in a traffic jam, on a long train ride, bored at home or in line at the doctor - play the suggested games. The baby is delighted and does not whine: “I’m bored, when will I finally...”, and the parent’s heart rejoices - the child is developing!

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

Invite your child to sit, relax and close his eyes. Let him imagine in front of him a blank album sheet, pencils, and an eraser. Now invite your child to mentally draw on a piece of paper 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 this, you should open your eyes and check: close your eyes and imagine the same sheet of paper - if the picture does not disappear, you need to mentally take the eraser again and erase the picture until it disappears completely. It is recommended to repeat the exercise periodically.

By the way, when you do something with both hands at the same time, for example, play a musical instrument or even type on a keyboard, both hemispheres work. So this is also a kind of training. It is also useful to perform familiar actions not with your dominant hand, but with the other. Those. right-handers can live the life of left-handers, and left-handers, on the contrary, can become right-handed. For example, if you usually brush your teeth with the brush in your left hand, then periodically switch it to your right. If you write with your right hand, switch the pen to your left. It's not only useful, but also fun. And the results of such training will not take long to arrive.

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

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

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, think and love. The latter properties are unique to humans. Before answering the question of what the left hemisphere of the brain is responsible for, you need to remember 9th grade anatomy: what the brain consists of.

Brain structure

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

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

Between there is a longitudinal slot, 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 hemisphere controls the opposite side of the body. It follows from this that the left hemisphere is responsible for the right half of the body.

The brain has 4 lobes (we will talk about them below). The lobes are separated by three main grooves: Sylvian, Rolandov and parieto-occipital. In addition to the grooves, the brain has many convolutions.

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

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

The brain matter itself is divided into gray (cortex) and white. The gray is made up of neurons and lines the top of the brain. The thickness of the cortex is approximately 3 mm, and the number of neurons is about 18 billion. White matter is the pathways (neurocyte fibers) that occupy the rest of the brain. It is the cortex that controls a person’s entire life from sleep to the manifestation of emotions.

Functions of the left hemisphere of the brain

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

The cortex is divided into zones responsible for certain functions (vision, hearing, etc.), but they do not function separately. To say something, a person must first think, analyze, calculate. During a conversation, people show emotions (sadness, joy, anxiety, laughter), gesture, that is, use their hands and 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 lobes of the brain responsible for?

Interesting! Less than half of the human brain has been studied!

Frontal lobe of the left hemisphere of the brain

Responsible for movement, the ability to speak, individuality, thinking. - This is the part of the brain responsible for emotions, behavior, and thinking.

Motor cortex

Responsible for the activity of the striated muscles of the right half of the body, coordination of precise movements, and orientation on the ground. Impulses from internal organs go to this department. When it is damaged, ataxia, paresis of the limbs, and disturbances in the functioning of the heart, blood vessels, and breathing occur. The picture below shows the topical affiliation of organs and body parts to the precentral gyrus.

Speech motor area

Ensures the work of facial muscles to pronounce complex words and phrases. In other words, it is responsible for the formation of speech. In all right-handed people, the speech motor area in the left hemisphere occupies a larger area than in the right.

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

Parietal lobe

This is where the sensitivity zone of the skin, muscles, and joints is located. Impulses from the skin receptors of the arms, legs, and torso on the right go to the left hemisphere. If this area is damaged, sensitivity in some parts of the skin is impaired, and the ability to identify objects by touch occurs. The sense of touch is lost, the perception of temperature and pain in the right extremities, as well as the torso on the right, changes.

Temporal lobe

The auditory zone is responsible for hearing and vestibular sensitivity. When the zone on the left is destroyed, deafness occurs on the right side, and the ability to hear in the left ear sharply decreases, 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 area of taste and smell works together with the stomach, intestines, kidneys, bladder, and reproductive system.

Occipital lobe – visual area

The visual fibers at the base of the brain also cross, as do the auditory fibers. 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 is affected.

The occipital part of the brain is also responsible for the visual speech center, 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, and touch.

The difference between the left hemisphere and the right

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

Features of the left hemisphere:

Logic, analysis, thinking.
Numbers, mathematics, calculation.
Step-by-step solutions to complex problems.
The ability to understand literally.
Clear facts, arguments, without unnecessary information.
Teaching foreign languages, the ability to control speech.

All about functions, disorders and their consequences.

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

Everything about: from anatomy to diseases.

What is the right hemisphere of the brain responsible for?

Intuition, imagination, emotions.
Perception, musicality, artistry.
Fantasy, bright colors, the ability to dream.
Creating an image from a description, a passion for mysticism and riddles.

How to determine the dominant hemisphere?

They say that right-handers have a more developed left hemisphere, and 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 interested in painting, music, and at the same time not believe in mysticism. In fact, it is difficult to say which hemisphere is dominant, since both of them work when required.

The human brain is the most inaccessible and difficult to study. Even in the era of the introduction of new modern research methods, the brain has not been fully studied. 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 average weight of the adult human brain is about 1.4 kg, that is, about 2 - 3% of the total human weight
Brain size does not affect mental abilities in any way, as has been proven in recent studies

In this article, we will take a detailed look at the structure and functions of each hemisphere and conduct a test that will establish which hemisphere 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, and learning them from them is not particularly difficult. The reason for memorizing new languages lies in the high development of the left hemisphere
The predisposition to good linguistic memorability rests on 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 more the left side predominates, the faster the child begins to speak, while maintaining the correct structure of speech
Performs sequential (logical) information processing
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 humans
The ability to establish cause-and-effect relationships based on logical beliefs, that is, a person is predisposed to the fact that every piece of information received 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 person’s more explosive character and control of the search and acquisition of new information

Functions of the right hemisphere

Historically, for a long period of time, 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, citing its uselessness.

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

The predominance of the development of nonverbal and holistic representation, that is, the information received is expressed not verbally, but by symbols or some images
Characterized by visual-spatial perception. Thanks to this ability, a person has the ability to navigate the terrain
Emotionality. Although this function does not directly relate to the hemispheres, the development of the right side has a slightly more 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 understanding will easily understand what he is talking about.
Creative predisposition. It is individuals with predominant development of this part who in most cases become musicians, writers, etc.
Parallel information processing. The right hemisphere has the ability to process various sources of data. Incoming information is not processed based on a logical sequence, but is presented as a whole
Controls motor abilities on the left side of the body

Studies of the function of the cerebral hemispheres on the right side show that it is also responsible for reducing the negative reaction to stressful situations, emotions and trying to avoid something unknown.

Test to determine the dominant hemisphere

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

Exercise No. 1

You need to 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 finger is taller.

Exercise No. 2

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

You should be careful when viewing through the hole, since when inspecting any thing, it will shift somewhat. Write down on a piece of paper in which eye the displacement occurred.

Exercise No. 3

Cross your arms in the chest area and write it down on a piece of paper, which turned out to be higher.

Exercise No. 4

Clap your hands a couple of times and write down on a piece of paper which hand 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 your dominant hand P - right hand, L - left hand. Then compare with the results below:

PPPP - this suggests that you most likely have no desire to change anything, that is, there are certain stereotypes that you follow
PPPL – lack of determination in any issue or action
PPLP – high communication skills and artistry
PPLL - decisive character, but at the same time there is gentleness towards others
PLPP – predisposition to analytics, high caution when making any decisions
PLPL - there is a susceptibility to the opinions of others, 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 a person has only one part of the brain functioning, 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 would correspondingly 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 interconnectedly that our life appears to be a complete picture with logical, emotional and other equally important components.

What are the left and right hemispheres of our brain “responsible for?”

The human brain remains the most poorly understood organ. Despite the fact that research in this area has been going on for more than a hundred years, the secret of brain function remains a mystery. The most complex biological mechanism that nature has ever created is the human brain. This piece of gray matter remains a huge blank spot on the map of human knowledge.

Most of the brain mass, namely 70%, is located in the cerebral hemispheres. The corpus callosum, which connects the left and right hemispheres, consists of neurons that ensure the exchange of information between the hemispheres.

The two hemispheres of our brain share certain functions. The left hemisphere is responsible for logical and abstract thinking, the right for motor skills. The two hemispheres can complement each other. If one of the hemispheres is damaged, its functions are transferred to the other half.

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, motor control, positive and negative emotions, attention, memory. The highest function performed by the brain is thinking.

There are schools that favor one hemisphere over the other. Thus, schools that develop the left hemisphere focus their attention on logical thinking, analysis and accuracy. While the right-brain school focuses on aesthetics, feelings and creativity.

The right hemisphere mainly “serves” the left side of the body: it receives most of the information from the left eye, ear, left arm, leg, etc. and transmits commands to the left arm and leg accordingly.

The left hemisphere serves the right side.

Usually one of the hemispheres in a person is dominant, which is reflected in the individual properties of the personality. For example, left-hemisphere people are more drawn to science. Right-hemisphere people are more eager to engage in art or areas of activity that require individual imaginative solutions. The vast majority of great creators - composers, writers, poets, musicians, artists, etc. - "right-brain" people. But there are individuals who work with both hemispheres.

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

Left 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 is this that 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 abilities: 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 of 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.

Right hemisphere

The main area of specialization of the right hemisphere is intuition. As a rule, it is not considered dominant. It is responsible for performing the following functions.

Processing nonverbal 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 location perception and spatial orientation in general. It is thanks to the right hemisphere that you can navigate the terrain and create 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 other people's imagination. Thanks to it, we can understand not only the literal meaning of what we hear or read. For example, if someone says: “He’s hanging on my tail,” then the right hemisphere will understand exactly what 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 create different stories. By the way, the question “What if...” is also asked by the right hemisphere.

Artistic ability: The right hemisphere is responsible for visual arts abilities.

Emotions: Although emotions are not a product of the functioning of the right hemisphere, it is more closely related to them than the left.

Sex: The right hemisphere is responsible for sex, unless, of course, you are too concerned about the technique of this process itself.

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 simultaneously process a lot of different information. It is able to look at a problem as a whole without applying analysis. The right hemisphere also recognizes faces, and thanks to it we can perceive a collection of features as a whole.

Controls 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.

How can you check which hemisphere is more developed in you?

Squeeze your palms in front of you, now interlace your fingers and notice which hand’s thumb is on top.
- clap your hands, mark which hand is on top.
- cross your arms over your chest, mark which forearm is on top.
- determine the leading eye.

How can you develop the abilities of the hemispheres.

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

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

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

1. Preparation for the exercise.

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

Visualize your brain as consisting of two hemispheres and divided into two halves by the corpus callosum. (See pic above) Focus on your brain.

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

2. Doing the exercise.

We inhale slowly, fill with air and hold our breath for a short time. During exhalation, we direct the stream 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.

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

Left: inhalation, pause, exhalation associated with the projection of the number.
Right: inhalation, pause, exhalation 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 as long as it evokes pleasant sensations. Letters and numbers can be swapped, or replaced with something else - for example, summer - winter, white - black.

"Ear-nose."

With our left hand we take the tip of the nose, and with our right hand we take the opposite ear, i.e. left. At the same time, release your ear and nose, clap your hands and change the position of your hands so that the right one is holding the tip of the nose, and the left one is holding the opposite one, i.e. right ear.

"Ring".

"Mirror drawing"

Brain training with imagery

The left hemisphere of the brain deals with logical thinking, while the right hemisphere deals with visual thinking and feeling.
Part 1:

Sadiya, immerse yourself in a state of inner peace, transparency, a state when nothing bothers you.

Imagine (imagine) in turn:

In the left hemisphere of the brain

Medieval religious procession of a group of monks

Blooming trees

Snow covered peak

Sunrise

Hot summer day

Red color

Theater stage

Slowly flowing river

Feeling when touching soft silk

Sandpaper feeling

Feeling like your fingers are sliding on a piece of ice

The sound of a big ball hitting

The sound of a blacksmith at work

Sound - a cat meows

Lemon flavor

In the right hemisphere

Whirlwind on the coast

Galaxy

Snow covered peak

Autumn day

Thick fog

sandy desert

Touching a piece of corrugated steel

Feeling of smooth, cool glass

The hand is in warm water

Car engine noise

Sound of a bell

The sound of a dog barking

Taste of chocolate bar

Take a few deep breaths. Stand up slowly. Walk around the room a little, suggesting that you are becoming more alert, your consciousness is more active. And immediately do part 2.

Part 2:

Look up with your left eye, as if you were looking at the left hemisphere of your brain.

Look up with your right eye, as if you were examining the right hemisphere of your brain.

Try to rotate your eyes vertically. It's like they're spinning right in the middle of the head.

Circle 2 circles with your eyes on the left side of your head.

Circle 2 circles with your eyes, on the right.

Draw your eyes around many circles that fit into each other. The circles are tilted at different angles. Circles fill the entire head.

Rest for a while, don't do anything.

Circle the circle with your eyes: it is located horizontally, at eye height. The next circle is a little smaller. Draw many circles like this until they turn into a dot.

Stop your eyes on this point. And keep them there as long as possible. But don't tense up or hold your breath.

When your eyes move from this point, draw them again in many circles that converge to a point.

Take a few deep breaths. Stand up slowly. Walk around the room a little, suggesting that you are becoming more cheerful, your consciousness is becoming more active.

And immediately do part 3.

Part 3:

Imagine the right hemisphere of your brain.

Focus on the right hemisphere,

On it - like a supersensitive organ,

On the curves and irregularities on the surface,

On the nerve that connects the 2 hemispheres,

On millions of brain cells.

Try to feel the 2 hemispheres of the brain.

Think about the electrical and chemical processes going on in the brain.

Name the colors, not what is written.

The right hemisphere of the brain recognizes colors, the left hemisphere reads. This exercise involves balancing the hemispheres and training their interaction. For safety (from user glitches), the test begins and ends with the “correct” word-color combinations.
