What is the cerebral hemisphere responsible for? The left hemisphere of the brain is responsible for good mood. Synchronized work of both hemispheres

American neurosurgeons Joseph Bogen and Philip Vogel, as well as neuropsychologist Roger Sperry In the middle of the 20th century, it was established that the right and left hemispheres of the brain perform different cognitive functions. However, the results of their research were misunderstood by many, which led to the belief that one of the hemispheres of the brain predominates in all people: the right is responsible for logic and reasoning, and the left is for imaginative thinking and creativity.

In fact, all people almost equally use both the right and left hemispheres of the brain. However, each of them provides different principles of reality perception, speech organization and color recognition.

Perception of reality

The right hemisphere perceives information as a whole, provides the perception of reality in its entirety of diversity and complexity, as a whole with all its constituent elements. It works simultaneously through many channels and is able to restore the whole in its parts, in particular, it is responsible for the perception of location and spatial orientation.

Organization of speech

The right hemisphere of the brain forms the integrity of the semantic content, provides figurative thinking, creates associations. It is based on a metaphorical representation of the objective world.

Color recognition

The right hemisphere of the human brain provides the perception and verbal coding of basic, simple colors, such as blue, red, etc. In general, the right hemisphere is responsible for the formation of rigid links between the object and color, color and word.

How does the right hemisphere of the brain work in lefties?

According to sociologists, from 5 to 15% of the inhabitants of the Earth are left-handed. Scientists have found that the use of their left hand as a leader is associated with the peculiarity of the functioning of their brain. It is believed that the right hemisphere of the brain of these people is responsible for the tasks that the left hemisphere of right-handed people copes with, and vice versa. This is partly true, but there are some peculiarities. For example, when moving the dominant hand, the brain of right-handers is activated locally in the left hemisphere, while in left-handers it is activated in both. In a state of calm wakefulness, the cerebral hemispheres of right-handers work more synchronously than those of left-handers. But during the transition from wakefulness to sleep, the picture changes: for right-handers, synchrony in the work of the hemispheres is disturbed, and for left-handers, it changes slightly.

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 membranes on top (soft, hard, arachnoid). 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. 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 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:

Logic, analysis, thinking.
Numbers, math, calculation.
Step by step solution of complex problems.
The ability to understand literally.
Clear facts, arguments, without unnecessary information.
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?

Intuition, imagination, emotions.
Perception, musicality, artistry.
Fantasy, bright colors, the ability to dream.
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 brain is the most important organ of the body, consisting of. To understand the characteristics of a particular person, it is important to know what the right hemisphere of the brain is responsible for, and what the left hemisphere is responsible for.

A person has sense organs with which he is connected with the outside world:

hearing;
vision;
smell;
taste and tactile sensations through which he receives information.

And all this processing is done by the brain. In addition, it is used to:

planning action;
making decisions;
coordination of movements;
recognition of emotions, dividing them into positive and negative;
development of attention and memory;
thinking (highest function).

The hemispheres of the brain are not separate structures that work in isolation. Between them there is a gap with the corpus callosum. This helps both hemispheres to function in a coordinated manner.

All movements of one side of the body are controlled by the opposite side of the brain. So, if a person makes a movement with his right hand, it means that she received an impulse from the left hemisphere. In people who have experienced a stroke (impaired circulation in the brain), the side of the body that is opposite to the affected area is paralyzed.

The brain consists of two components - gray and white matter. , all human activity is under its control, and white is nerve fibers that perform many functions that guide the coordinated work of both hemispheres. Gray matter is formed in a person under the age of 6 years.

Functions of the left half

Due to the fact that the brain consists of two hemispheres, each of them is involved to a greater or lesser extent and performs its functions. This discovery was made less than a century ago by the American neurosurgeons Bogen and Vogel and the neuropsychologist Sperry.

The left hemisphere is responsible for a person's ability to use language as a means of communication. It controls:

speech process (construction of phrases, vocabulary);
the ability to decipher information received with the help of the organs of vision;
the use of graphic characters in writing;
important information.

A person differs from the entire animal world in that he is the only one who has developed the ability to think, for which the left hemisphere is also responsible.

This side of the brain is capable of not only receiving information, but also processing it. It is the left hemisphere that recognizes numbers and symbols, because it can decipher them.

Since thanks to the left hemisphere a person is able to think logically, it was this part of the brain that was considered the leading (dominant) for a long time. But this is only true when the functions are executed:

speech;
letter;
solving mathematical problems;
movement on the right side of the body.

Usually different types of activity require the activation of a certain part of the brain.

Tasks of the right half

The ability to think in humans exists not only due to the work of the left half of the brain, but also the right hemisphere. But for a long time, scientists did not see much benefit from the right hemisphere, and surgeons, if damaged, could remove it, considering it to be the same rudimentary organ as the appendix.

It got to the point that a child who learned to write and took a pen in his left hand was retrained and forced to work with his right hand.

Since intuition and concrete imaginative thinking are the merit of the right lobe, these functions were not considered important. And intuition was generally ridiculed, and its existence questioned. It has been proven that this is nothing more than a myth.

Today, those people who can think outside the box are especially valuable, and their creativity is a bright feature of a creative person. Psychologists believe that for a long time the upbringing of children was left-brained. Therefore, in bookstores you can find collections of exercises with which you can learn how to stimulate the right hemisphere of the brain.

Based on this, the question arises: if a scientist has developed logical thinking, what is the left hemisphere of the brain responsible for, then why does he need the right one? Maybe he doesn't need it?

Over time, scientists came to the conclusion that the functions of the right hemisphere are important for the rest of the brain. It turned out that most mathematicians simultaneously use the thinking style characteristic of the opposite share. Ordinary people think with words, but during scientific activity, imagery is often connected to this. Therefore, this ability of both lobes to synchronize results in non-standard solutions, inventions, and innovations in various areas of life.

Albert Einstein began to speak and write late as a child. This means that his right hemisphere was actively developing during this period. Thanks to him, he created his own signs of inner speech, and then used them in scientific activities. This world-famous scientist was not given school sciences, except for mathematics. Nevertheless, he became an educated person and created the physical theory of relativity, the quantum theory of heat capacity.

An analysis of his brain showed that the left and right hemispheres of the brain are more connected than in ordinary people, and some areas are enlarged. This feature allowed a world-famous scientist to give mankind useful inventions.

The right hemisphere of the brain is responsible for processing non-verbal information, which is presented in the form of pictures, signs, symbols, schemes. In addition, a person who has a developed right lobe is different in that he:

navigates in space, collects puzzles;
has an ear for music and ability to music;
understands the subtext of what is said;
able to dream and fantasize, invent, compose;
has the ability to be creative, in particular, to draw;
processes information in parallel from several sources.

These abilities make people interesting, extraordinary, creative.

Development of the hemispheres

The brain of a child works differently than that of an adult. These differences are due to the fact that in a baby everything develops in stages, while in an adult it is an already formed organ.

Scientists have proven that the most important periods influencing the development of emotions, processes of cognition and adaptation in society are years from 1 to 4. The rate of formation of new neurons in a child is 700 per second. In an adult, the number of connections gradually decreases (hence the forgetfulness, inattention, slow reactions in the elderly).

First, the child actively develops the zones responsible for perception - vision and hearing. Then the area responsible for speech is activated. Then the process of cognition is formed.

Many parents want their child to develop according to their goals. And if the baby does not live up to their expectations, they try to "re-profile" the brain of children and end up with an artist or mathematician.

Each person owns a tool for the development of the brain - these are his fingers. To make a small child speak faster, they do fine motor skills exercises with him. To get the active work of the left and right hemispheres, they try to do not quite standard actions during the day. For example, lovers of drawing try to do it in a mirror image.

Another exercise is the "Ring". It is made from the thumb and forefinger. Then alternately the thumb is connected to the middle, ring and little fingers. This must be done as quickly as possible. First with one hand, and then with both at the same time.

During normal exercise, one must often connect opposite limbs: the left hand with the right foot and vice versa. You can reach your right ear with your left hand, then everything is exactly the opposite. It is useful to do daily tasks with an inactive hand:

fasten buttons on clothes;
write on paper;
sweep;
wipe the dust;
use cutlery.

As a result, the productivity of different parts of the brain.

Those who want to do exact sciences do not need to specialize only in logical problems. By developing imaginative thinking, one can achieve significant results even in physics and mathematics.

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 have a developed right hemisphere are called) 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 left hemisphere of 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 on 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 the head or by successively concentrating 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 kinds of early development methods 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, therefore, when a child grows, 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 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, 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 whole 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 instance: " 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.

Structure of the brain

The mass of an organ in an adult is approximately 1400 g. It is located in a cavity, covered with membranes on top (soft, hard, cobweb). 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.

How to determine the dominant hemisphere?

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:

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.

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.

Exercise #3

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

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 missing. 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.

How to unleash the potential of your brain, what to become a darling of fate? Secret revealed! It is necessary to develop the right hemisphere ...

Imbalance in human development

Managing your own brain¹ is a completely natural process, planned for a person by nature itself.

But history has taught people to pay attention to the external, forgetting about the internal. The same goes for the brain. According to studies, on average, people use the potential of the brain by only 3-5 percent!

Unfortunately, most abilities remain for people beyond the bounds of the possible, something out of the realm of fantasy. It's the same with the brain: for most people, it works as it should.

A person is not able to fully control his memory and other neural processes of the brain, although it would seem that this should be as easy for him as the ability to raise a glass into the air. Therefore, we cannot independently solve problems with memory, develop imagination and much more.

Also with superpowers: esoteric texts say that every person can develop these abilities. But he cannot do this because of the underdevelopment of the right hemisphere of the brain.

Why strive to develop the right hemisphere of the brain?

Now people mostly use the left hemisphere. It is responsible for logic, analysis; the work of this hemisphere is alien to creativity, imagination and creative mental activity. It makes us good performers at best.

Only the right hemisphere makes it possible to be an active creator of your life, it is responsible for creativity, imagination, creation and intuition.

There are people whose brains spontaneously switch to a different mode of operation, including the right hemisphere. Such people usually make artists, actors, musicians and representatives of other creative professions.

But in science, and in technology, and in other activities, serious achievements are simply impossible without the involvement of the right hemisphere!

We can say that the right hemisphere creates ideas, while the left hemisphere directs, looks for ways of expression.

The potential of the right hemisphere

Every person is capable of awakening the right hemisphere and developing their psychic abilities. And as a result - to develop any talents in yourself and achieve success in life.

What is the difference between the activity of the right and left hemispheres?

The human brain is naturally electromagnetically active. This activity is expressed by a certain rhythm in which the brain works. It is the rhythm that determines what state we are in.

The electromagnetic oscillations of the brain produce a certain number of repeating cycles per second. The number of such cycles per second is the rhythm of brain activity. Rhythm has its own frequency. For most people, it can range from one cycle per two seconds to forty cycles per second.

Depending on the rhythm of brain activity, four main states of the brain are distinguished: alpha rhythm, beta rhythm, theta rhythm and delta rhythm.

For example, when a person is awake, his brain works in beta rhythm. When he sleeps, and the mind is turned off and does not see dreams, then the brain plunged into the delta rhythm: it rests in it.

How to develop the right hemisphere?

During light relaxation, an immersion in the alpha rhythm occurs. During sleep, the brain is in a state of theta rhythm. And this state is the key to the development of psychic abilities and the potential of the brain.

This state is difficult to catch, and at the same time, it can be learned: you need to increase your awareness, and just train your body to pay attention to this brief moment. In the state of theta trance, you can receive secret knowledge from the information field of the Universe³, control reality to achieve success in life, grant wishes, develop superpowers, and much more.
