The plot of many feature films and literary works is constructed around the answer to a question, how many percent of a brain the person uses. Also the assumption of opening of superhuman opportunities at its full use is usually told about activity of 10-15% of this body, from here. But whether there is some scientific confirmation to such conclusions, or it is only irrepressible imagination of writers?
How many percent of a brain are used by the person?
For a start It is necessary to tell, as till today the brain of the person is the most poorly studied body therefore it was always surrounded by the mass of myths. For example, long time was considered that the size of a brain of the person influences I.Q. Modern researches showed inaccuracy of this opinion, having proved lack of such interrelation. Mental capacities depend on quantity of nervous cages and their ability to quickly transmit signals, but the big size of a brain does not mean their high concentration at all. Such mistakes were frequent at the beginning of the neurobiological researches, here and with definition of work of a brain of the person as a percentage there was an embarrassment.
Long ago a talk about need of early training of children which can significantly increase IQ indicators was carried on. On the example of William Sidis (IQ 250) this theory was proved. Doubts in full use of a brain resulted, and attempts to calculate the valid level of activity of this body were made. The easiest way for the technologies existing at that time was to measure the number of active neurons in the small site of a brain. On the basis of these data the conclusion about activity of body in general, from here was made and these undertook 10% describing on how many the brain of the person works.
Confirmed this theory and that fact that insignificant injuries of a brain could not make serious impact on work of an organism in general. But later researches proved that this opinion is absolutely incorrect. Scanning of a brain shows lack of inactive zones, they can appear only at serious damages. Also it is impossible to dismiss evolution which quickly gets rid of all unnecessary and inefficient. That is the question, how many percent of a brain are used by the person, is absolutely inappropriate. Besides, not used nervous cages are inclined to degeneration that is not observed everywhere.
Possibilities of a brain of the person
If in terms of science of people completely uses the brain, so and you should not hope for expansion of its abilities?, It seems, everything is logical, time our control center is completely loaded, and additional resources have no place to undertake. But there is one subtlety which brings again to a question for how many percent the brain of the person works. But the speech any more not about the number of active neurons, and about quality of their use.
The fact is that the modern equipment is not capable to give the answer to a question of a way of emergence of the difficult communications forming consciousness. The structure of a brain at all is identical, and here mental capacities can significantly differ. It can mean that someone gets the rejected nervous cages, and existence of unsolved abilities of a brain. For the second theory says also that mental capacities give in to a training, all of us are engaged in it during training who does it more diligent, that also receives the best results. It turns out that possibilities of a brain depend on as far as the person uses it.
So if desired there can be the superman everyone, another thing is that not all will have enough time and patience to train abilities of the thinking for the sake of illusive prospects.
