  1. Psychologists define deja vu as a person's perception of new events or new information as already lived or seen before. According to statistics, approximately 97% of people, to a greater or lesser extent, experienced similar conditions. Where does it come from?

    Research on this phenomenon has been going on for quite some time. Many hypotheses were identified, but none of them could be proved. However, scientists were able to identify certain areas of the brain that are responsible for such a phenomenon as deja vu. According to doctors, at the time when a person begins to experience this sensation, a so-called dysfunctional electrical impulse occurs in his brain. At the same time, activity increases in the hippocampal zone and the middle temporal lobe — areas that are responsible for long-term memory. Since these areas remain hyperactive for some time, the brain simply cannot process incoming information properly. As a result, there is a strange feeling that events or phenomena that occur for the first time in a person's life have already taken place. Why is this happening? There are several hypotheses here. The first of them is more related to psychology, and says that this is due to anticipation or living situations in your head. The person has already lived the moment, building it in his imagination. And similar emotions complete the picture.

    Can you call it a brain malfunction? Rather, it is a small and harmless glitch in the memory area. And in order for the brain to constantly work without failures and function perfectly at any time, it is worth starting to develop it. For example, pay attention to board games, solve sudoku and crosswords, and read popular science literature. You can also try to start training on specialized simulators that develop attention, memory and thinking.
