What is the right hemisphere of the brain responsible for? What is the right hemisphere of the brain responsible for? What is the left side of the brain responsible for?

Every person has left and right hemisphere of the brain, and if one of them dominates, then a functional interhemispheric asymmetry of the brain, which determines not only the leading side of the body (right-handed, left-handed), but also the ways of thinking, perception and imagination ...

In a word, depending on the leading hemisphere of the brain, their asymmetry, your character, your personality, the way of writing a life scenario, behavior and activity will largely depend: the ability to achieve certain results in life.

Large hemispheres of the brain - functional interhemispheric asymmetry

This article is not for professionals and not for students, so this is not about what it is. cerebral hemispheres a person, not about anatomy and physiology - there is plenty of this material on the net.
This publication is for ordinary people: adults, adolescents and parents who want to understand how it affects their life, perception, thinking, intelligence, behavior, feelings, creativity and creativity, study and activity, on interpersonal communication and interaction, on mutual understanding and cooperation, on the upbringing of children, finally, how it affects the success and achievements in life functional interhemispheric asymmetry, i.e. the difference in the work of the left and right hemispheres of the brain, one of which, usually, is the leading (dominant).

Left hemisphere of the brain

Left hemisphere of the brain is responsible for the abstract-logical thinking of a person, i.e. thinking associated with the verbal (verbal) interpretation of concepts and phenomena. This is where speech comes in.
With the help of the left hemisphere of the brain, a person can speak, think, think logically and analyze situations, including the induction process.

People with a dominant (dominant) left hemisphere of the brain usually have a developed verbal intelligence, a large vocabulary, they are distinguished by talkativeness, activity, the ability to predict and foresee.

Right hemisphere of the brain

Right hemisphere of the brain is responsible for spatial-figurative thinking (non-verbal), which ensures the integrity of perception.

A person with a predominance of the right hemisphere of the brain is usually predisposed to daydreaming, fantasies, to subtle and deep feelings and experiences, he has a developed non-verbal intelligence, he is taciturn and slow.

Interhemispheric asymmetry of the brain

Functional interhemispheric asymmetry of the brain, i.e. when the left hemisphere performs some psychological functions, and the right one - others, and one of them is the leading (dominant).

Interhemispheric asymmetry is only partially congenital (for example, right-handed, left-handed), it acquires greater importance in the process of development, training, education and socialization. For example, a more educated person has a higher hemispheric asymmetry than a less educated person.

In a small child, a junior schoolchild, the leading hemisphere has not yet been determined, because his speech apparatus (left) and, accordingly, verbal-logical thinking is still in development. This can be easily seen, for example, when a child writes mirror letters or draws, he can write, say, a soft sign and "b" and "d", or draw from right to left, and vice versa - this is not a mistake, he sees that .e. sometimes with the left hemisphere and sometimes with the right.

Also, the upbringing of the child affects the interhemispheric asymmetry, usually, according to the traditional male or female life scenario, boys develop the left hemisphere more, and girls develop the right hemisphere (the so-called male or female logic)

Asymmetry of the hemispheres affects the future activities of a person, the choice of his profession. So, people with a dominant left hemisphere are better suited to professions related to speech, logical thinking, analysis of processes and situations.

For people with a dominant right hemisphere that influences creative activity, creativity of thinking, artistry and artistry, a profession with a predominance of imaginative thinking is more suitable.

Thus, depending on the predominance of one or the other hemisphere of the brain, people can be conditionally divided into two types: the thinking type, with the leading left hemisphere, and the artistic type, with the leading right one.

As for relationships in the family, with children, with friends, loved ones, at work .., here interhemispheric asymmetry in different people can help complement each other, and it can also contribute to the growth of competition and confrontation.

For example, a husband with a dominant left hemisphere may well be an addition to the marital functioning of a wife with a dominant right hemisphere. In fact, it will be, provided that the family is understood as a unity of "WE", a kind of symbiosis, as well as within the personality itself - the left hemisphere complements the right (and vice versa), i.e. the entire human brain works as a whole, and each part (hemisphere) performs its own psychological functions.

But, if, figuratively speaking, the left hemisphere begins to engage in creativity, and the right hemisphere begins to analyze and predict, then there will be an intrapersonal conflict and inadequate perception, behavior, personality split, and ... into the flesh to neuroses and psychopathology. (Something similar can happen in the family ...)

Or, if there are two people in the family, a partner with one leading hemisphere, right or left, then competition and confrontation may arise.

You can also notice a weak asymmetry of the cerebral hemispheres in women and men who are poorly educated or have ceased to develop their personality, who spend their time watching TV series, these people can so quickly make the presenter, then the right, then the left hemisphere, that they can simultaneously, especially for women, watch another series of melodrama and worry about the characters (right hemisphere), and, say, do household chores, for example, washing (left hemisphere) ... by the way, hence the name: "Soap Opera".

Psychological problems and asymmetry of the left and right hemispheres of the human brain

The human psyche can be divided into consciousness and unconsciousness. Those psychological problems that people are able to cope with on their own are easily recognized and can be analyzed and interpreted using the left hemisphere of the brain.
But what is stored in the unconscious; those unfinished situations, emotions, i.e. what is perceived and stored in the depths of the psyche with the help of the right hemisphere of the brain, and indirectly affects the quality of life, relationships, personal growth and prosperity, is not fully understood by a person and cannot be worked out without psychological help, without psychotherapeutic and psychoanalytic intervention.

Many methods of psychotherapy work precisely with the right hemisphere of the human brain, while the left hemisphere is trying to weaken a little or turn it off altogether, as, for example, in hypnotherapy.

Therefore, for psychoanalysis and psychotherapy, it is important to understand the interhemispheric asymmetry of a particular person.
Various techniques and observations are used to diagnose the leading hemisphere of the brain. Sometimes it is enough for an experienced psychotherapist to conduct a conversation in order to understand the asymmetry of a person's hemispheres.

Online Psychotherapist Preliminary Questions

The main secret of our body is the structure and function of the brain.

As you know, this most important organ consists of two hemispheres - left and right. M. Dax, a doctor from France, who studied this issue in detail, was the first to say about their inequality.

Based on the results of numerous studies, it can be concluded that in people who complain about, the left hemisphere of the brain does not work well.

This part of the brain determines a person's ability to think logically and speak... It is directly related to words, symbols, signs. The main difference between the left hemisphere and the right hemisphere is in the way the incoming information is processed. Thanks to the left hemisphere, we build complex phrases, but the right one is responsible for their emotional coloring.

If the left side of the brain is working normally, the person adequately evaluates the joyful moments that occur in life, not subject and has a good sense of humor... If the left hemisphere is damaged, a person disappears, negative emotions appear, he becomes aggressive.

The left hemisphere has another important function: it reacts to speech... It is noteworthy that they do not perceive any other sounds, be it the noise of the wind, rustling of grasses, laughter, etc. People with a well-developed left hemisphere view truth as a relative category, they successfully cheat, masterly embellish reality, and even deliberately deceive. This part of the brain is responsible for human intellectual abilities, counting, literacy, reading and linear thinking. The left hemisphere allows us to think methodically.

Work on the development of the left hemisphere should be carried out from early school age. Psychophysiologists note that for its normal operation it is important to regularly solve logical and mathematical problems. It is equally useful to solve crosswords. In the course of solving them, a person reasons, that is, he acts not intuitively, but analytically.

Another way to activate the left hemisphere is by training the muscles of the right side of the body. As a result of systematic complex exercises, memory is significantly improved, mood swings disappear, intuition develops.

To be in a good mood, you need to load the left hemisphere with work, and not necessarily difficult. You can, for example, put a few coins in your pocket and try to determine their value by touch, and then calculate the total amount.

Test: Which hemisphere is better for you?

To answer the question posed, it is proposed to complete simple tasks.

The principle is the same everywhere: if you do something better with your right hand, then your left hemisphere is more developed, and vice versa.

« Lock". Cross the fingers of both hands without thinking. The deciding factor is whether your left or right thumb is on top of you. If right, then the left hemisphere is more developed, and vice versa.
For the next task you will need to cross your arms over your chest... See which one is at the top? If you are right, then your left hemisphere is better developed.
Clap your hands... In doing so, pay attention to the leading hand, which moves more actively. If the left hand is more active, then the right hemisphere is more developed, if the right, then the left hemisphere.
Another interesting test is this: you need to make both hands work in sync... For example, take a pen in each of them. Draw different geometric shapes at the same time - a triangle, a square and a circle. Drawings made by the leading hand are distinguished by greater clarity of lines.
Prepare a sheet of paper. Put a dot (bold) in its center. Take a pencil in your right hand and close your eyes... Now try to hit the improvised target at least fifteen times. Then do the same manipulation with your left hand. Now analyze in which case the hit accuracy is higher.
Take a blank sheet of paper and draw two squares and a half by one and a half centimeters on it. Further you need to quickly shade them(the first - with the right hand, the second - with the left, or vice versa). Now see which square has more lines. The dominant hand shaded shape will have more stripes.

If you succeed that most tasks you perform better right hand, then you are dominated by left hemisphere(since the left hemisphere is responsible for the right side of the human body, and the right for the left side). And vice versa.

Of course, the informative value of one test may be lower than that of another, but in combination, they allow to determine with maximum reliability which hand of the subject is the leading one. Thanks to simple tests, it will be possible to establish the functional specialization of the cerebral hemispheres. This information will help you determine which exercises to focus on.

So what exactly is left brain activation? This is the sequential excitation and inhibition of neurons. This process can be influenced in different ways. It turns out that a good mood is no longer an abstract state, but a completely achievable goal. You can look at the world in a new way, if you yourself want to. There are no more obstacles.

Develop both your hemispheres and have a good mood!))

Hello dear readers of my blog! Today we will focus on the left hemisphere of the brain, which is responsible for logical thinking and speech, and also we will analyze how to develop and activate its functions. In the previous article, I described his “brother” - which is more responsible for creativity. By balancing the work of both parts, you can achieve great results and success in all areas of life, so this is an important thing for almost all people.

The left hemisphere of the brain is sometimes referred to as the dominant one. Firstly, because in 90% of people it is more developed than the right one, and secondly, the role of its mental functions in human activity is difficult to overestimate. Let's consider them in more detail.

Left hemisphere functions

Thinking

Both hemispheres are involved in thinking, but they are responsible for different aspects. So the left hemisphere, in contrast to the right, which considers the situation as a whole, processes information sequentially. It analyzes each individual fact and gives a logical assessment.

Verbal speech

One of the main functions of the left hemisphere is verbal speech. This is our ability to speak, read and write. In people with a damaged left side of the brain, speech functions are impaired and it is difficult to perceive information. Learning foreign languages is easier for people with well-developed left-sided thinking.

Check

The left hemisphere is also responsible for recognizing symbols and numbers. With its help we solve mathematical problems and equations, we can remember dates and phone numbers.

Establishing causal relationships

Thanks to the left hemisphere, humans are able to trace causal relationships and draw conclusions. Therefore, the left-sided mindset is also called analytical. People who have this kind of thinking often go to work as investigators, analysts, etc.

Positive emotions

In the course of recent psychological studies, it was found that the left hemisphere is responsible for positive emotions, and the right for negative ones.

Right side control

The left hemisphere controls the work of the right side of the body, and vice versa. That is, when we write with our right hand or perform some other action, this means that the signal came from the left side of the brain.

Properties of left-sided thinking

The functions listed above are performed by the left hemisphere in all people. But it also has the properties of a narrower specialization that predominate in people with left-sided thinking. They are characterized by such qualities as purposefulness, logic, practicality, quick learning, organization.

In my article on the right hemisphere, I talked about the fact that it is responsible for creativity. But if people with right-sided thinking, the left hemisphere is poorly developed, it is difficult for them to realize their ideas, due to inconsistency of actions and lack of purposefulness. Therefore, harmonization of the entire brain is very important.

Left hemisphere activation

There are special exercises to help turn on the left hemisphere. But even if it already dominates you, extra training will not hurt.

Solving problems

Math and logic puzzles perfectly develop the left hemisphere of the brain. You can start with the simple ones and then move on to the more complex ones.

Solving crosswords is good, especially Sudoku, as they are based on numbers and require logic and analysis to solve.

Physical exercise

To activate the left hemisphere, you need to use the right side of the body. For example, perform normal activities with your right hand (write, brush your teeth, stir tea). For right-handers, this will not be difficult, but left-handers will have it more difficult.

Also, while doing regular gymnastics, pay more attention to the right side of the body. For example, you can jump on the right leg, bend to the right, etc.

Self-massage

There are many points on the human body that are responsible for various organs, including the brain. At the base of the big toes is the point responsible for the cerebellum, and below it are the points of the cerebral hemispheres. By massaging the point under the big toe of your right foot, you activate the left hemisphere.

Fine motor skills of the hands

Fine motor skills of the hands are very useful for the development of the hemispheres. There is a special exercise for this. Place the tip of your right little finger against the tip of your left thumb and your left little finger against your right thumb. Roll your hands so that the position of the fingers is reversed. Then the same thing needs to be done with the ring and index fingers.

But the best way for this is to touch the rosary with the right hand. Then you immediately execute 3 functions:

activate the left hemisphere
meditate
massage the points on your fingertips

Pain in the left hemisphere

Many people suffer from a headache located on the left side of the head. The most common condition that causes such pain is migraine. Experts identify the following reasons:

physical and psychological exhaustion;
dehydration of the body;
stress;
poor blood circulation to the brain

To relieve migraine symptoms, you need to drink plenty of water and give the body a rest. Meditation can also help. Pranayama is especially good. Breathing exercises can help oxygenate the brain and improve circulation.

But it must be borne in mind that pain in the left side of the head may indicate other diseases more serious than migraine, so if you do not know what is their cause, it is better to consult a doctor.

I told you about the functions of the left hemisphere and about its activation, but for the brain to function more efficiently, both parts of it must be developed. And which hemisphere you have, you can write in the comments to the article. I will also be glad if you share your knowledge about exercises to activate brain activity. Best regards, Ruslan Tsvirkun.

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

Let's see what our cerebral hemispheres are responsible for and why some people are active mainly on the left, while others have the 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, speaking and writing. Thanks to his work, a person can memorize 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.

What is the right hemisphere of the brain responsible for?

Right on the lusphere of the brain is responsible for processing of non-verbal information expressed in images, and not in words. Here are the human abilities for various types of creativity, the ability to give dreams, fantasize, compose. It is responsible for generating creative ideas and thoughts.

Also right the 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 a well-coordinated work of both hemispheres is needed for a successful human life.

Which hemisphere of your brain is active?

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

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

Some can observe the moment of a 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 and right hemispheric brain activity, the so-called ambidextrous.

They can achieve the effect of changing the direction of rotation by tilting the head or by consistent concentration and defocusing of vision.

But 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 the child learns the world with the help of images, then 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, stock up on all sorts of early development methods and practically from the cradle begin to teach our children to read, count, try to give them encyclopedic knowledge, giving early stimulation to the left, and the figurative, intuitive right remains, as it were, out of work.

And, therefore, when a child grows up, 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 right away that I do not urge you to let the mental development of your children take their course. Vice versa! Age under 6 is the most successful age for developing the potential of the brain. It's just that development should not be as early as timely. And if it is inherent in nature that at an early age the right dominates in children, then maybe it is worth developing it, not trying to stimulate the work of the left early with methods aimed at developing logical thinking?

Moreover, the opportunities that our children lose in childhood precisely because of the lack of training in the right hemisphere include truly phenomenal abilities. For example: memorizing unlimited amounts of information with the help of images (photographic memory), speed reading and this is just the beginning of the list of superpowers that your child can possess with the correct 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 brain is the main organ of the central nervous system, which consists of a huge number of nerve cells and their processes, interconnected with each other. This organ is almost completely occupied by the cavity of the cerebral section of the skull. It protects the brain from external damage. As a person develops and matures, the brain gradually takes the form of a cranium.

Due to the activity of the brain, a person sees, hears, walks, works, experiences emotions, is able to communicate with other people, analyze, think.

Structure

In adult men and women, the total mass of the organ is about 1.3-1.5 kg. Male and female brains differ little in weight (in women it is slightly lighter), while in newborns the weight of the organ is no more than 350-400 g, and in a 12-year-old child - ~ 800-1000 g. The brain is located in the cranium and is closed with three shells. It has a specific structure. The most essential parts of the organ are: the oblong and the posterior (which includes the pons and the cerebellum, located behind the pons), the anterior, intermediate, and midbrain.

The right and left hemispheres of the brain are responsible for the regulation of higher nervous activity, because they have departments that are responsible for writing, speech, hearing, vision. Thanks to the cerebellum, balance is ensured, and the trunk contains developed centers that control the respiratory and cardiovascular systems.

In men, the brain completely ceases to increase in size by about 25 years, while in women this process is completed by 15 years.

There is a longitudinal slit between the two halves of the organ, the basis of which is the corpus callosum, which connects the hemispheres, ensuring the coordination of their work with each other. Ever since school times, from anatomy, we know that the halves are responsible for the work of the opposite sides of the body. For example, the right half is responsible for the functioning of the left side of the torso.

Left hemisphere functions

The cerebral hemispheres are interconnected with the rest of the central nervous system, therefore they function in conjunction with the subcortical structures.

If one of the hemispheres is damaged, then another part of its functions may take over. This testifies to the conjugate provision of the work of movements, higher nervous activity, sensitivity, and sense organs.

In the cortex there are several zones at once, which are responsible for the performance of specific functions. These zones only work together. For example, if a person wants to say something, then he thinks, analyzes, calculates, and then only speaks. In the process of communication, people express emotions: they grieve, rejoice, worry, laugh, etc., gesticulate, using their facial muscles and hands for this. Such work is ensured by the general functioning:

several zones of the cortex;
subcortical nuclei;
spinal and cranial nerves.

At the moment, the human brain has been studied by world science by less than 50%, but the process continues continuously.

Frontal lobe of the left hemisphere

If we talk about what the left hemisphere is responsible for, then first you should talk about the frontal lobe, due to which the person's ability to speak and think is provided. This is one of the most important parts of the brain. Thanks to her, emotions appear and manifest themselves, behavior and thought processes are controlled.

Reciprocating zone

Allows to ensure the normal functioning of the facial muscles, which is necessary for pronouncing difficult phrases and words. To put it differently, thanks to the speech-motor zone, speech is formed in a person as a whole. If he is right-handed, then in the left hemisphere the speech-motor zone takes up much more space than in the right, and if he is left-handed, everything is exactly the opposite.

If the zone is destroyed or severely damaged, the ability to speak is automatically lost. In this case, a person will be able to sing and shout without words. Also, if damaged, the ability to read to oneself, to formulate one's thoughts is lost. Such damage does not affect the function of understanding the speech of other people.

There is a widespread myth that a person uses only 5-10% of the capabilities of his brain. This is not the case, because cells that are not recruited simply die off.

Motor area

The left and right hemispheres contain the motor cortex, which is necessary for the activity of the striated muscles. In the left hemisphere, the activity of the right side of the body, coordination of movement accuracy, orientation on the ground are controlled. The internal organs send their impulses to this zone.

If the motor cortex is damaged, then the following problems are observed:

disturbances in the work of the cardiovascular system, respiratory organs;
paresis of the limbs;
ataxia.

Parietal lobe

There is a zone of sensitivity of muscles, joints, skin. The left hemisphere receives impulses from the receptors on the right side of the body.

If this area is damaged, then, in most cases, a person experiences sensory disturbances in some parts of the body, he will lose the ability to identify things by touch. There is also a loss of touch, sensitivity to ambient temperature, pain is not felt in the right side of the body.

Temporal lobe

Its main functions are vestibular sensitivity and hearing. If the zone is damaged, the right ear will cease to hear, the ability of the left ear to hear normally will be lost. The person will move less accurately, and will stagger when walking. Not far from the temporal lobe is the auditory center of speech, due to which we can understand addressed speech and hear our own.

Occipital lobe

At the base of the brain, the intersection of the visual and auditory fibers occurs. Therefore, impulses from the retina of the right and left eyes enter the visual zone of the left hemisphere. Moreover, if the area is damaged, then complete blindness in a person will not occur - violations are observed only in the left eye.

The occipital part of the head is also necessary to ensure the normal functioning of the visual speech center - with its help we recognize the written words and letters, we read.

Hemisphere specializations

The left and right hemispheres of the brain are responsible for certain functions.

The main specialization of the left hemisphere is logical thinking, therefore it was previously widely believed that it was the left side that was dominant. But the dominance of the left hemisphere is observed only in the implementation of certain functions:

Language abilities, ensuring speech control, the ability to read and write, memory (memorizing facts, names, dates, etc., writing them), learning foreign languages.
Comprehension of words (the left hemisphere can understand the meaning of what is said only literally).
Analytical thinking (recognition of numbers and mathematical symbols, logic, analysis of facts).
Sequential processing of information (the left hemisphere performs processing of the received information in stages). The left side considers all the available details - it does not see the whole picture, unlike the right side, therefore it is not able to put together the information received.
Mathematical abilities (the left side recognizes symbols, numbers, a logical and analytical approach is used to solve mathematical problems, which are also provided by this hemisphere).
Control of the right side of the trunk (if you raise your right leg, this will indicate that the corresponding command came from the left hemisphere).

The hemispheres of the human brain interact with each other, so when thinking, the central nervous system uses them together. There is a synchronization of the functioning of the two hemispheres. The central nervous system activates them and connects the obtained results. But all the same, it is customary to clearly distinguish between their mental functions.

It is widely believed that the larger the brain, the smarter and more brilliant a person is, but this is a delusion. Albert Einstein had a relatively small brain that weighed about 1.2 kg. The size of the organ does not in any way affect the quality of mental activity.

There is a clear separation of certain functions. The right hemisphere is largely responsible for intuition, so it cannot dominate. Its main functions also include:

Processing of non-verbal information (symbols, images).
Spatial orientation. The hemisphere allows a person to orientate in space, to correctly perceive their location. Due to the work of this side of the brain, a person is able to competently find the way to the right place, taking into account various factors, create mosaic puzzle images.
Metaphors. Thanks to the work of the hemisphere, people can correctly perceive metaphors, guess riddles, and recognize the results of the activity of another person's imagination. If the left hemisphere allows us to literally understand and analyze the meaning of what has been written, then the right hemisphere takes a creative approach. For example, if we hear such a metaphor: “Simple as a felt boot,” then due to the work of the hemisphere, we will understand what they wanted to convey to us.

Mystic. Religion, mystical phenomena, superstitions and much more from these areas - the right hemisphere of our brain is responsible for all this.
Musicality. Creativity also belongs to the sphere of activity of the right hemisphere. Talents in the field of music, the ability to perceive musical works and much more related to music and other creativity are provided by the work of this side of the brain. It is interesting to note that not the right, but the left hemisphere will be responsible for obtaining music education.
Imagination. Thanks to the right side of the brain, we can dream, imagine, fantasize. The hemisphere completely controls these processes, allows us to come up with all kinds of stories, develops thoughts related to coming up with new solutions and paths, make predictions, combine memories into a single whole, etc. For example, it is the right side that asks questions like "What if?" and many others related to the creative thought process.
Emotions. If we talk about what our right hemisphere is responsible for, then the list also includes emotions, which, in fact, are not a product of the activity of this hemisphere. At the same time, they are connected with the right side much more than with the left, which scientists have long been able to prove.
