Myths about Brain

Myths about Brain

There are some common misconceptions about human brain and the way it works. In this article, you will find out the reasons why these notions were formed.

Brain uses only 10% of its possibilities

It is not true. Scientists claim that when the brain activity, particularly the activity of nerve cells, is recorded, one can count how many neurons are active with the help of with a separate electrode. Knowing the sensitivity of the electrode and the distance it can "contact" neurons, by means of morphological slices we can establish that in a given volume of brain there is, for example, 1000 cells. In this case, we can detect that the amount of active neurons is very small, something about 5-10%, or even less.

However, such understanding of the brain’s work is a mistake, because the registration of these neurons happens at the moment when an animal or a person carry out some kind of behavior being engaged in some activity. A person cannot simultaneously drive the car, read a book, play the piano and ski. Accordingly, at a time when we perform a certain activity, the activity of a certain group of neurons could be recorded, and at other times the activity of some other group, and so on. Thus, the registration of a very small percentage of neurons involved in a particular activity does not mean that the brain is not using all 100%, but only 10% (working “badly”).

The left hemisphere of the brain is responsible for rationality, and the right one for creativity

It is not clear what hemisphere predominates in solving rational and creative tasks, as this leads to a highly simplified understanding of how the brain works. It is incorrect to assume that one hemisphere is responsible for one kind of task solving processes, and the second - for the other as the entire brain is somehow involved in all the mental processes.

However, there are problems in which one of the hemispheres is largely involved. For example, when it comes to solving spatial problems the right hemisphere is dominant, but the left one makes an important contribution to these processes. If you need to write an essay or a summary of some content, first you must understand it and right and left hemispheres will be involved in this process. However, in the creation of a text the left hemisphere will be more involved.

The brain works like a computer

It is not true. Very often, perceptions about brain and consciousness were associated with technological innovations, which were currently central. When the clock was the latest innovation in technology, the brain was represented as a set of gears. Later, when the telephone network appeared, the brain was often represented as a switching device, which connects bunches of wires.

Therefore, it is not surprising that today the brain is compared to a computer, as it is the universal tool for calculations that allows solving many problems. In the reality, the difference between a computer and a brain is fundamental.

In a computer memory, and computations are separated. In turn, in a brain, this division is absent. Memory and computations are combined because memory is stored in the structure of connections between nerve cells that perform the calculations.
