10 myths about the brain, which you should not believe in
The human brain is a complex complex organ, in the mechanism of work of which scientists have not yet figured out. At all times, the brain has been associated with a variety of myths, many of which are still very common. Due to the fact that the brain is still little understood, it is difficult for a person “from the outside” to understand how true this or that statement about this body is. Here are the 10 most common myths about the brain that the Science Alert portal collected.
There are “right hemisphere” and “left hemisphere” people
It is believed that logical and rational people have more developed the left hemisphere of the brain, and the creative – the right. This is not so – no scientific studies that would confirm this difference were carried out, rather the opposite. In 2013, at the University of Utah, the specialists studied the brains of more than a thousand people and found that there was no particular difference between these brains, and the MRI scans showed that both parts of the brain in all cases worked more or less equally .
We use only 10% of the brain
Evolution would not allow this. Spend so much resources, growing such a large brain, so that later its owners do not use it as much as possible – at least, it is illogical. In fact, we use almost the entire brain, even the simplest tasks require the coordination of many of its regions – although there are still small reserves.

Everyone has his own type of perception
Many people believe that there are audials and visuals, kinesthetics and digitalis – depending on how it is easier for a person to perceive information. This is not so, at least, there is no scientific confirmation of this myth. On the contrary, when experimenting with students who used their preferred type of training in preparation for the exams, it turned out that the way information is received does not affect the result of the exam in any way.
After 40 people think worse
Yes, some cognitive skills deteriorate with age – for example, it’s easier for children to learn new languages or remember some words. But on the other hand, older people have more vocabulary, they are better versed in nuances, and even more correctly evaluate people, solve conflicts and on average better keep themselves in hand.
Men and women learn differently
Again, the myth. Yes, men usually have more brain, but this is explained more by the fact that the man himself is usually larger than the woman. So far, there is no scientific confirmation that neurons in the brains of women and men are reported differently depending on gender.
There are only five senses
Everything is much more complicated, maybe there are up to 21 ways to perceive something, and the five senses are the most common of their combinations. So, touch is the perception of pressure, heat and pain. In addition, there are also feelings of hunger, thirst and balance, and they are also a way of perceiving oneself and the world.
Alcohol kills brain cells
Yes, alcohol is harmful, but to reach the concentration that the cells would die from its effects, it is quite difficult – by this time the whole organism will be poisoned. The harm that alcohol does to the brain is that the damage is obtained by the processes of neurons , dendrites, which prevents them from relaying messages to each other at the same speed. And here …
Nerve cells can not be restored
It has long been proven that this is a myth. The brain has excellent compensatory abilities, and even after serious injuries, its plasticity helps to partially restore the functional. It used to be that a person has a finite number of brain cells, but now science already knows that the brain can both produce new cells and “repair” the old ones.
Found stem cells responsible for brain regeneration
We know exactly what is good for us and what’s bad
Too wrong. Each of us has an idea of ??what we like or do not like, but in fact we do not have the faintest idea of ??what will please us or grieve at a particular moment in time. Studies show that people tend to overestimate the potential positive (from a fun party) or negative (from Monday morning) emotions .
Listening to Mozart is useful for the mind
The only scientific work that showed that students after listening to Mozart’s works pass tests for the intelligence factor better, and did not receive confirmation. Nobody ever managed to repeat this result.
