Have you ever had a feeling of déjà vu from time to time?
From a psychological point of view, this is called the "hippocampus effect".
What is the hippocampus effect?
The "hippocampus effect", also known as déjà vu and déjà vu, is the feeling that human beings suddenly feel that they have "experienced a certain picture or experienced something in a certain place" in a real environment (as opposed to a dream).
According to most people's recollections, it seems that they have seen a certain scene in a dream, but have forgotten it. Later, when they encounter this scene in reality, they will have the feeling of "deja vu".
Why does the hippocampus effect occur?
The brain science community generally believes that this is due to short-term confusion in the storage of memory, causing the brain to regard the information just obtained as a long-term memory. Surrounded, because at this time the brain is unable to process the received consultation volume one by one.
Explained from a medical point of view, the cause is the incoordination of information processing between the left and right brains. "Deja vu" is the result of the interaction between the intuitive system and the memory system in people's brains.
So, is the hippocampal effect good or bad?
There is no distinction between good and bad hippocampal effects. The hippocampus effect is also a kind of psychological effect. It is not predictive. It is manifested in some scenes you see and you feel that you have experienced it before, and you seem to have known each other.
Surveys show that more than two-thirds of adults have experienced it once or more. Generally, people with stronger imagination and higher IQ have a greater probability of this phenomenon. In addition, the probability of hippocampal effect in youth is higher, and then decreases with the increase of age. The more colorful people's lifestyles, the more frequent the hippocampus effect appears.
