Revealed the secret of deja vu

It turns out that our brains for some reason, travels into the future. And remember what they saw there

The impression that I have been here has been …

Each of us at least once in a lifetime cover sudden and strange feeling … We know for sure: this is what is now, the first time. But suddenly realize that it has happened once: here I was, I saw the same person, I heard these words, and as the light fell. Currently allegedly found with the past …

Phenomenon is called deja vu — "already seen."

Thus, the great Swiss psychologist and philosopher Carl Jung that feeling for the first time visited in 12 years. And since he was convinced that he lives a parallel life and partly remains in the XVIII century.

Cases of deja vu describe Jack London, Conan Doyle, Clifford D. Simak in the book "The Reserve goblins." In the popular American film "Groundhog Day," the main character every day, waking up, falls into the same day. He was surprised to discover that there is no change either in the room or in the scenery outside the window. And whichever way he tried to change the situation, this day has been repeated over and over again.

And some of the manifestations of the phenomenon can be so ironic that all led to believe in the transmigration of souls.

For example, when the singer Madonna first looked around the Imperial Palace in Beijing, she had a feeling that she was in it knows every nook and cranny. It gave her a reason to say that in a past life she was a servant of the last Manchu emperor.

First arrived in Egypt, Tina Turner suddenly saw familiar landscapes and objects. And suddenly "remembered" that at the time of the Pharaohs was a friend of the famous Queen Hatshepsut or even the queen. A "007" Sean Connery recently was sure that was a healer in the militant African tribe of natives.

But we know that not a single moment of history is not experienced twice.

Whence did undertake such strange memories of the past and the future?

MAP OF NEW PLACES

Experts from the Massachusetts Institute of Technology recently announced that they have solved the mystery of deja vu.

— We found the area of the brain responsible for the formation of this mysterious feeling, — assured the team leader, a biologist Suzumiya Tonegawa, a Nobel laureate in 1987. — Our experiments have shown that the main role played by the neurons in the memory center of the brain — the hippocampus. Specifically — it dentate gyrus, which allows you to quickly — almost instantly — to identify the smallest difference in a similar way.

Through the activities of this section a person realizes what impressions resemble those he had seen, and what is fundamentally new. The hippocampus as a dividing human experience of the past and present. But when two experiences are very similar, in the hippocampus fails. Which leads to a déjà vu.

Researchers believe that a set of neurons, called them "cell sites" creates a kind of "snapshot" of the project of any new places in which we find ourselves. Because we unconsciously begin to represent yourself, using the previously stored information. And when we see the same place already awake, we try to compare the "virtual" image of the present. And if the process for some reason fails, such as stress or fatigue, the brain begins to consider before a simulated image or the real situation and as a result produces a "false" memories as true. And then we feel that we have been in this place, even though we are in it for the first time.

Blooper

According to Igor Vysokova, the department of general regularities of mental development Institute of Psychology Vygotsky's deja vu — it's probably a bug that occurs because of the similarity of situations. Man watching the circumstances really have similarities with the past, confuses staging — they fused to form a single event. That is in the heart of this phenomenon is only the ability of the human brain to the associative thinking. Often the effect occurs only when a small trinket of remote connection to the past of man. For example, a person may seem that he has met this passer, if he suddenly sees in it a jacket that he once wore in his youth.

In favor of "associative" version of this phenomenon, and said the experience conducted by psychologists at the University of Leeds. They managed to find a way to artificially induce a person a sense of deja vu. Volunteers showed on the screen a list of 24 words. Then hypnotized. In a state of trance, participants in the experiment were told that when they see the words in the red box, these words will be familiar to them, even though they will not know where and when they were seen.

After coming guinea shows old and new words in the different colors. Of the eighteen subjects in ten people had the feeling that the words in the red part they've seen somewhere, even if it were completely new words.

However, psychophysiological cause of the phenomenon is still not clear: My only comment is that déjà vu is shown on the background of frequent fatigue and stress. We also learned that this phenomenon is most concerned about 17-year-olds who have already secured the minimum luggage impressions and very sensitive to a variety of life situations. A second and final wave of deja vu for some reason comes in 35 — 40 years. And the most susceptible to this feeling melancholic with a keen sense of life, a very nervous and impressionable.

Expert evidence

Senior Fellow, Institute of Humanitarian Research RSUH higher Ph.D. Leonid KARASEV:

— My explanation of this phenomenon is the closest thing to a "holographic" hypothesis. Holographic principle means that each point in the image contains enough information to recreate it on the big picture no matter what angle it falls view. So, probably, built, and this amazing phenomenon. In coded form in the brain stores almost all the information that we face in life. But all we have seen and heard, hidden so deep that to get it in the usual way is almost impossible. This information can jump through just a little detail. Some smell, sound, light, fleeting meeting with some passers-by can you create the illusion that you are in this situation turned out to have 5 — 10 years ago. Although the detailed analysis shows that it is very much not the same.

Director, Center for Mental Health, RAMS Alexander Tigani:

— The phenomenon of déjà vu is closest to paramnesia, that is, to a distortion of memory of psychopathology. It can occur in otherwise healthy people. Nevertheless, each person with such phenomena must be carefully examined to ensure that it does not have lesions in the brain. After all, this unusual effect in some cases can develop into amnesia, when the past completely disappears from consciousness. Or, conversely, to give impetus to the emergence of fantasy type of delirium, hallucinations or idée fixe.
