Determine which hemisphere of your brain is dominant

• Areas of specialization of the left hemisphere
• Areas of specialization of the right hemisphere
• Table of distribution of characteristics of the right and left hemispheres

If the figure steadily rotates only clockwise, it means that your left hemisphere is dominant, left-hemisphere brain activity predominates.
And this is logic, calculation, the ability to speak and express thoughts. Rotating only counterclockwise means your right hemisphere dominates, and predominantly right-hemisphere activity predominates - eidetics, intuition, imaginative thinking, musicality, a sense of orientation in space and time.

If the figure rotates alternately in one direction or the other (see instructions below), or you can change the direction with the power of thought, this is a sign of ambidexterity (Latin ambi - double; dextrum - right), that is, the work of both the right and left hemispheres of the brain. Ambidextrous people are a special group of people with extraordinary abilities. Suffice it to say that there are many such people among the Seyids - the direct descendants of the Prophet Muhammad, among the Levites and Kohanim, and other outstanding people. For example, Vladimir Putin is ambidextrous.

• For some, this switching of the rotation of the silhouette in the appropriate direction occurs when the head is tilted to the right or left.
• For others, a change in the direction of rotation is noted when the gaze is concentrated on the face, then it becomes defocus, and vice versa.
• Or, alternatively, shift your gaze by about 15 degrees. left-down - rotates to the left. Shift your gaze to 15 degrees. right-down - rotates to the right.
• You can also look at the girl's heel or her shadow.

Areas of specialization of the left hemisphere

Processing verbal information: The left hemisphere of the brain is responsible for your language abilities. This hemisphere controls speech, as well as reading and writing abilities.

It also remembers facts, names, dates and their spellings.

Analytical thinking: The left hemisphere is responsible for logic and analysis. It is this that analyzes all the facts.

Literal understanding of words: The left hemisphere can only understand the literal meaning of words.

Sequential thinking: Information is processed by the left hemisphere sequentially in stages.

Mathematical abilities: Numbers and symbols are also recognized by the left hemisphere.

Logical, analytical approaches , which are necessary for solving mathematical problems, are also a product of the work of the left hemisphere.

Control of movements of the right half of the body. When you raise your right hand, it means that the command to raise it came from the left hemisphere.

Areas of specialization of the right hemisphere

Processing of nonverbal information: The right hemisphere specializes in processing information that is expressed not in words, but in symbols and images.

Parallel information processing: Unlike the left hemisphere, which processes information only in a clear sequence, the right hemisphere can process a lot of different information simultaneously. It is able to look at a problem as a whole without applying analysis.

The right hemisphere also recognizes faces , and thanks to it we can perceive a collection of features as a whole.

Spatial Orientation: The right hemisphere is responsible for location perception and spatial orientation in general. It is thanks to the right hemisphere that you can navigate the terrain and create mosaic puzzle pictures.

Musicality: Musical abilities, as well as the ability to perceive music, depend on the right hemisphere, although, however, the left hemisphere is responsible for musical education.

Metaphors: With the help of the right hemisphere, we understand metaphors and the work of others' imaginations. Thanks to it, we can understand not only the literal meaning of what we hear or read. For example, if someone says: “He’s hanging on my tail,” then the right hemisphere will understand exactly what this person wanted to say.

Imagination: The right hemisphere gives us the ability to dream and fantasize. With the help of the right hemisphere we can create different stories. By the way, the question “What if...” is also asked by the right hemisphere.

Artistic Abilities: The right hemisphere is responsible for artistic abilities.

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

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

Mysticism: The right hemisphere is responsible for mysticism and religiosity.

Dreams: The right hemisphere is also responsible for dreams.

Controls the movements of the left half of the body: When you raise your left arm, it means that the command to raise it came from the right hemisphere.

The dominant hemisphere of the brain is a myth

This is the brain. One of the most complex things that exist in the universe. Without exaggeration, there are more neurons in your head than stars in the galaxy. But we know much more about how stars and planets interact than we do about what's going on in our heads. And because it's such a complex web of nerves and cells and connections, most of us like to simplify things like this.

There is one thing that everyone knows about the brain: that it is divided into two halves - the left and right hemispheres. It is believed that the left side is mainly responsible for logical thinking: this includes mathematics, sequencing, language, facts, and so on; the right side of the brain has more creative functions, such as imagination, intuition, visualizing our feelings and all that kind of stuff. Because of this, the idea has become generally accepted that most people are either left-brained or right-brained, just as we are left-handed or right-handed. Accountants, lawyers and bankers are all smart and serious left-brain dominant people. Artists, musicians and hairdressers are all wild and impulsive right-brain people. But is this true? Could one part of your brain be dominant? Answer: no.

Moreover, our brains are not nearly as divided as most people imagine. The two hemispheres are much more similar than we think, and most processes occur on both sides. The two parts do have different functions, but they are not separated as simply as logic on one side and creativity on the other. An example would be the following: the left brain will take over the work with a mathematical equation, and the right will begin to compare quantities and evaluate them.

Both of these operations are part of mathematics, so the two halves work together. And when we say that the left brain deals with language, it really deals with words and grammar, while the right brain deals with context and intonation. It is thanks to this that you are able to distinguish a conversation with a person from a conversation with a robot.

So where did this idea of ​​a left and right brain divide come from? It's actually based on the work of Nobel Prize winner in physiology or medicine Roger Sperry. He was trying to find a way to help people with extreme forms of epilepsy and was the first to perform brain surgery in which he cut the corpus callosum, which is the largest link between the two hemispheres. While performing the operation and studying the patient’s condition afterward, he noticed that there were differences between the hemispheres.

Newspapers and magazines simply picked up this idea and went with it to the masses. But modern research disproves this theory. A study published in 2013 looked at 1,000 people using MRI scans of the brain to see if one side of the brain was truly dominant when performing certain functions. But they never found any preference in the functioning of the hemispheres. Instead, they saw both halves working together to complete tasks. In reality, this is because most problems are more difficult than they seem at first glance. For example, when you try to recognize an object, the brain actually goes through several different steps. The left hemisphere looks for details, while the right hemisphere looks at overall shape. In general, the right hemisphere looks at things more holistically, taking into account the big picture, while the left hemisphere looks at the fine print. You can't say that one side of the brain or the other is doing the task. Both hemispheres work together to find a solution.

And if you still needed some definitive proof that the idea of ​​a right brain and a left brain has no relation to reality, then we have some very extreme examples. It turns out that a person can function normally with only half a brain. In 1923, a surgeon named Walter Dandy at Johns Hopkins University was the first in history to perform surgery on a patient with a brain tumor. The operation, known as a hemispherectomy, involved removing half of the brain. It was then performed hundreds of times throughout the 20th century, mostly on children suffering from persistent seizures. Doctors were amazed that even after half their brains were removed, their memory, personality and speech developed normally. Hemispherectomies were 86% successful in treating seizures, and most children continued to perform well in school.

Of course, there are a few disadvantages to only having half a brain. Patients stop seeing with the eye opposite the distant hemisphere and lose the ability to control the corresponding hand. However, this procedure shows how incredibly flexible our brains are. Many brain functions can be moved to different parts of the brain. This way, some people can recover from brain damage or from having part of the brain removed. So the idea of ​​left or right brain dominance is a myth, but who knows what else we have to learn about the most incredible part of our body.

Table of distribution of characteristics of the right and left hemispheres

Let's start the test:

1 task. Interlace your fingers, bending your arms in front of you. Determine which of the two thumbs is on top? If the left one is on top, write the letter L and vice versa. Task 2 . Fold both hands into a pistol shape, extend them forward and take aim. Fix the aiming point. Both eyes are open! Close alternately your right and left eyes. If the point has moved with the right eye closed, put the letter P, if with the left eye closed, put the letter L. Task 3. Cross your arms over your chest - “Napoleon pose”. Look which hand is on top. Write the letter P or L. Task 4. Give a round of applause. When clapping, determine which palm was on top, more active. Place the appropriate letter. As a result of the psychological test you passed, you obtained a certain combination of letters corresponding to some type of interhemispheric asymmetry and, accordingly, a certain type of behavior.
