The right hemisphere of the brain works. The left hemisphere of the brain is responsible for what? How to develop the left hemisphere of the brain? What the Study Says

Statement:

The mindset of people with a developed right hemisphere of the brain is creative, and those with a developed left hemisphere are analytical.


Roger Sperry

neuropsychologist

“Indeed, the cerebral hemisphere is an independent cognitive system that perceives, reflects, remembers, reasons and reacts in its own way. […] Both hemispheres can simultaneously process information about the world around them, but in completely different, even mutually contradictory mental experiences that run in parallel.”

Why this is not true:

All people use both the right and left hemispheres of the brain to the same extent.


Although most right-handers have a speech center in the left hemisphere, it does not follow from this that capable writers and speakers use it more often than the right. An experiment by scientists from the University of Utah showed that the hemispheres of the brain are not tied to any type of activity. Dr. Jeff Anderson, Chief neurosurgical department University, and his team tracked the functioning of 7,000 brain regions in more than 1,000 people. The subjects were between 7 and 29 years old and were resting during the experiment.

It turned out that the number of nerve connections in both hemispheres is no different, and people use them with the same intensity. In order to think creatively or analytically, a person must use connections between all parts of the brain. So the next time you see another test that supposedly establishes which hemisphere is dominant in you, feel free to ignore it.

Guys, we put our soul into the site. Thank you for that
that you are discovering this beauty. Thanks for the inspiration and the goosebumps.

Back in 1981, scientists from the USSR came up with a test that allows you to determine with incredible accuracy the dominant hemisphere of the human brain. Different hemispheres are responsible for different actions, thinking and approaches to problem solving.

Knowing which hemisphere is better developed, you can choose the most suitable profession or explain your seemingly strange behavior in any situation. And parents can determine the child’s skills and talents and, depending on this, decide whether to send him to the chess section, for example, or to drawing.

website invites you to take this test, and at the end he will tell you a few interesting facts about you.

Prepare before you start

Take 2 sheets of paper: on one you will record the results, and you will need the second to complete some points. After completing each task, mark the result by writing it down on paper. The entire test will take you no more than 7 minutes.

1. Interlace your fingers

Place your hands together and interlace your fingers. Thumb Which hand was on top?

If with your left hand, then put the letter “P” on the sheet, if with your right hand, then put the letter “L”.

  • There is no mistake here. Each hemisphere of the brain controls the opposite side of the body, so if it is dominant right hand, that is left hemisphere, and vice versa.

2. Rosenbach test

Take a pencil in your hand and stretch it out in front of your eyes, as in the picture. Now look at the tip of the pencil and take aim. Close first one eye, then the other. When you close which eye, the image shifts more?

If, when closing the right eye, the image shifts more, then put the letter “L” on the sheet, if the left eye - “P”. If the image moves equally, then set it to “zero”.

3. Napoleon Pose

Stand up and cross your arms over your chest, like in the picture. Which hand is on top? If the hand is left hand - put “P”, if the hand is right - “L”.

4. Applause

Clap your hands and pay attention to which hand is on top.

If left palm- put the letter “P”, if the right one - the letter “L”.

5. Cross your legs

Squat down with your legs crossed. Which leg was on top? If it’s right, put the letter “L”; if it’s left, put the letter “P”.

6. Wink

Which eye did you wink with? If the right one is “L”, the left one is “P”.

7. Rotation

Stand on your feet and rotate a little around your axis. Which direction did you rotate? Counterclockwise - “L”, clockwise - “P”.

8. Strokes

Take the second piece of paper. Now with each hand, not to mention, draw several vertical strokes in a row. Then count the strokes. Which hand did you draw the most strokes with?

If you drew more with your left hand, write the letter “P”; if with your right hand, write the letter “L”. If there are the same number of lines, then write “zero”.

9. Circle

Using either hand, draw a circle and end it with an arrow. If the line goes counterclockwise - put “L”, clockwise - “P”.

It's time to enter your data into the formula. Don't be scared, it's easy

Count the number of letters "L" and write this number on the left top part formulas. Count the letters "P" and write the number in right side formulas.

Then calculate the result:

More than 30% - complete dominance of the left hemisphere.
From 10% to  30% - incomplete dominance of the left hemisphere.
From −10% to +10% - incomplete dominance of the right hemisphere.
More than −10% - complete dominance of the right hemisphere.

Some facts about you

  • The left hemisphere is the center of speech, which is why “left-hemisphere” people love to talk. But the left hemisphere can only understand the literal meaning of words.
  • But right hemisphere is responsible for intonation. “Right-brained” people speak little, but pay attention Special attention intonation.
  • The right hemisphere is sensitive to humor and understands metaphors.
  • The left hemisphere does not perceive music - the right is responsible for it.
  • Identification of common human faces- function of the right hemisphere. Therefore, “left-brained” people may not recognize you on the street.
  • “Left-brain” people like to go into details and are scrupulous.
  • The right hemisphere gives us the ability to dream and fantasize. With the help of the right hemisphere we can create different stories.
  • “Right-hemisphere” people first “grasp” the image as a whole, and then highlight the details.
  • “Left-hemisphere” people first highlight details, and from the details they form an idea of ​​the subject as a whole.
  • The right hemisphere is good at remembering emotions, feelings, personal experience.
  • The left hemisphere remembers logical connections, graphs and systems.

The brain is the most important part of the human nervous system, reliably protected cranium. This organ contains a huge number of neurons interconnected by synoptic connections. When these neurons interact, impulses of complex origin arise in the human brain, which, thanks to nervous system, are transmitted throughout the human body and allow control of the entire body.

Despite a fairly long period of study by the whole world of the processes occurring in the human brain, little is known about this surprisingly important organ; it still remains a particular mystery how the processes of control of the entire body proceed through one small mass inside the cranium. However, several facts were still discovered over the years of research. So, it is known for sure that h a person can only control the most a small part your brain. Another point everyone knows is that human brain consists of two hemispheres: left and right. The functions and features of the left hemisphere will be discussed further, and methods of its development will also be described.

basic information

As mentioned earlier, the brain is usually divided into left and right hemispheres. They are separated from each other by the cerebral cortex, but do not lose connection, because the normal functioning of this organ is possible only with optimal interaction of both hemispheres. This is why the human brain has corpus callosum. Each hemisphere has its own functions. Conventionally, it is the left hemisphere that is responsible for sequential execution of certain tasks.

The right one, no less important, also needs to perform a number of secondary tasks in parallel. Very often in everyday life they say that creative people the right hemisphere is more developed, and people with a developed left hemisphere are successful in exact sciences, for example in mathematics or physics. And this is quite logical, because the right hemisphere is responsible for processing information that enters the human consciousness in the form of images and symbols. But the features and functions of the left hemisphere are worth considering in more detail.

Function of thinking

Unlike the legal hemisphere, the left is responsible for processing facts coming from outside, for which logical thinking is used. IN in this case specific information is taken into account, while factors such as feelings and emotions play absolutely no role. It is worth noting that it is the left hemisphere, as mentioned earlier, that tends to process several tasks one after another, which contributes to the analysis of facts.

Verbal function

It is the left hemisphere that is responsible for verbal abilities to a person. Depending on the degree of development of these abilities, a person develops writing skills and text reading abilities in different ways. In addition, it is thanks to the work of the left hemisphere of the brain that a person can contact the outside world through speech and, of course, develop communication skills.

Human body monitoring function

In terms of control of the owner's body by the brain, the human body resembles a mirror. So, the left hemisphere controls the right half human body, and the right hemisphere controls the left half. That is, to put it differently, raising your right hand or taking a step right foot forward, a person carries out these actions precisely due to the work of the left hemisphere of the brain.

"Account" function

The so-called “counting” function applies only to the left hemisphere. Its main significance is reflected when a person carries out mathematical and other accurate calculations. In other words, it is the left hemisphere that sends signals to the whole body when solving mathematical or physical problems, calculating a budget, mentally adding up the amount to buy a particular thing, etc. Therefore, it is fair to say that if a child is gifted in the aspect of, for example, algebra, then his left hemisphere is developed.

Development of the left hemisphere of the brain

Very often, many people have a question: “Is it possible to develop the left hemisphere of the brain? And if so, how?". The answer will be yes. And here are some options:

  • It was mentioned earlier in the article that right body controlled by the left hemisphere. Adding here the fact about the positive effect of physical activity on brain development, we can conclude: for the development of the left hemisphere of the brain, it is necessary to give physical exercise right half of the body.
  • Since the left hemisphere is responsible for counting and logic, attention should be paid specifically to solving mathematical problems. Of course, it is not necessary to take on problems in higher mathematics right away. It's better to start with simple equations, gradually increasing the difficulty level. This will definitely help the development of the left hemisphere.
  • Strangely, the best and easiest way to develop the left hemisphere of the brain is to solving crossword puzzles. When trying to guess the word that needs to be entered into the cells, analytical thinking, characteristic of the left hemisphere, especially works.
  • And finally, it is necessary to remember the special tests, which contribute to the development of the left side of the human brain. Fortunately, a huge variety of them can now be easily found on the World Wide Web.

Collaboration

It should be noted that the hemispheres cannot work separately. Therefore, when developing one hemisphere, it is necessary to devote time to the development of the second. Plays a role here social factor, because people whose left and right hemispheres are equally well developed, that is, both creative and logical abilities, are more in demand in society.

Moreover, there is special people, the so-called ambidextrous people, whose hemispheres are equally developed. Sometimes such people can even write equally well with both hands. Anyone can achieve such heights of mastery, but it takes a lot of effort.

Interesting video about the work of the hemispheres:

Every person has left and right hemisphere of the brain, and if one of them dominates, then a functional interhemispheric asymmetry brain, which determines not only the leading side of the body (right-handed, left-handed), but also 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 you write a life script, behavior and activity will largely depend on your ability to achieve certain results in life.
(dominant hemisphere test)

Large hemispheres of the brain - functional interhemispheric asymmetry

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

Left hemisphere of the brain

Left hemisphere of the brain is responsible for abstract logical thinking person, i.e. thinking associated with 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 process of induction.

People with a leading (dominant) left hemisphere of the brain usually have developed verbal intelligence, great vocabulary, they are distinguished by their talkativeness, activity, ability to forecast and foresight.

Right hemisphere of the brain

Right hemisphere of the brain is responsible for spatial-imaginative 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, subtle and deep feelings and experiences, he has developed non-verbal intelligence, he is taciturn and slow.

Interhemispheric brain asymmetry

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

Interhemispheric asymmetry is only partially congenital (for example, right-handed, left-handed); it acquires greater significance in the process of development, training, education and socialization. For example, more educated person the asymmetry of the hemispheres is higher than that of a poorly educated person.

U small child, junior school student The leading hemisphere has not yet been determined, because his speech apparatus (left) and, accordingly, verbal-logical thinking are still in development. This can be easily noticed, for example, when a child writes mirror letters or draws, he can write, say, soft sign and “b” and “d”, or drawing from right to left, and vice versa - this is not a mistake, he sees it that way, i.e. sometimes with the left hemisphere, and sometimes with the right.

Also, interhemispheric asymmetry is influenced by the upbringing of a child; 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 influences a person’s future activities and choice of profession. Thus, people with a dominant left hemisphere are better suited for professions related to speech, logical thinking, and analysis of processes and situations.

In people with a dominant right hemisphere, which influences creative activity, creative thinking, artistry and artistry are more suitable for professions with a predominance of imaginative thinking.

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 hemisphere.

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

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

But, if, figuratively speaking, the left hemisphere begins to engage in creativity, and the right hemisphere begins to engage in analysis and forecasting, then an intrapersonal conflict and inadequate perception, behavior, a split in personality will arise, and... all the way to neuroses and psychopathology. (Something similar can happen in a family...)

Or, if there are two people in the family, partners 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 stopped developing their personalities, who spend their time watching TV series; these people can so quickly make either the right or the left hemisphere the host that they can simultaneously, especially for women, watch the next episode of melodrama and worry about the characters (right hemisphere), and, say, do household chores, for example, laundry (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 which 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 realized by a person and cannot be worked out without psychological assistance, without psychotherapeutic and psychoanalytic intervention.

Many methods of psychotherapy work specifically with the right hemisphere of the human brain, while trying to weaken the left hemisphere somewhat or turn it off completely, as, for example, in hypnotherapy.

Therefore, for psychoanalysis and psychotherapy it is important to understand the interhemispheric asymmetry of a particular person.
To diagnose the leading hemisphere of the brain, use various techniques and observations. It happens that it is enough for an experienced psychotherapist to conduct a conversation to understand the asymmetry of the human hemispheres.

Preliminary questions for a psychotherapist to provide psychological assistance online

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 suggest A complex approach to develop both halves. Then you will be successful in any activity, and also learn how to masterfully control your hands, and, moreover, perform various functions simultaneously.

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 left hand or leg up, this means that the opposite hemisphere has started working, since left-hand side your body obeys it. It is generally accepted that the orientation of a person with a dominant right half is directed towards 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

  1. So, in order to improve your creative side, you should visit exhibitions, museums, art galleries, and, of course, try yourself in writing poems, stories, practice drawing, even if it’s abstract and understandable only to you. Dancing helps coordinate movements, which also has a beneficial effect on development.
  2. Start practicing visualization techniques that will help you achieve your goals faster and also help you develop your ability to fantasize and daydream. This is easy to do, just study it first, where I talk in detail about all the nuances of the practice.
  3. 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. Detailed instructions you will find .
  4. Massage yours left ear, this will help activate the right side of the brain. Suitable in cases where it is necessary to take a creative approach to solving any issue and rely on your intuition.
  5. 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. In addition, you are aware that people who use humor and sarcasm in their speech have high level intelligence?
  6. 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 that your consciousness and subconscious have organized.

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.

  1. 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 it with yours peripheral vision, without taking your eyes off the selected point, consider what is to your left, and then to your right.
  2. 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.
  3. 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.
  4. 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
