Surely, everyone familiar with such moments, when it seems that a certain event has happened, or we met a man who had once seen.But that's how it was and under what circumstances, alas, no one can remember.In this article we will try to understand what deja vu is and why it happens.It's the game that started us the mind, or some mystic?How do scientists explain this phenomenon?Why is deja vu?Consider more detail.
What is deja vu?
Literally translated this concept as "previously seen."For the first time this term was used by Emil Buarakom - a psychologist from France.In his work "The psychology of the future" and voiced the author raised such moments, which describe earlier researchers did not dare.After all, no one knew exactly what deja vu is and why it happens.And this time there is no logical explanation of how it is possible to affect such sensitive issue?It is this effect is called the first psychologist term "deja vu."Before that, it used such definitions as "paramnesia", "promneziya", which means "already proven", "previously seen."
question of why there is a deja vu, and to this day remains a mystery unsolved until the end, though, of course, there are several hypotheses.
relationship with this people
If scientists do not always dare to describe the effect and its causes, many people are afraid and do such phenomena.By the feeling of deja vu, some are with great caution, considering that there were irregularities in the mental state.Naturally, the person who has experienced this effect in itself, is not always keen to share their feelings with loved ones, in fact, he tries to quickly throw all this out of memory and forgetting.If only people knew what deja vu is and why it happens, it would solve many of their problems.After all those events, phenomena, sensations that are below understandable inevitably cause fear.These effects include, and deja vu.How to spell the word - the question is not so urgent and vital.After all, people are much more interesting to find out what it is - a brain game or a dream that we once saw.Let's examine some explanations of this phenomenon.
What the scientists say?
American scientists have conducted several studies to find out how an effect of deja vu.They found that because of its appearance meets the hippocampus - a specific part of the brain.After all, there are specific proteins, which enable us to instantly recognize patterns.In this study, researchers even determine which cells have a structure of this part of the brain.It turns out that as soon as we find ourselves in a new place, or draw attention to the face of a man, all this information immediately "pops" in the hippocampus.Where did it come from there?Scientists say that his cell beforehand create the so-called "cast" of any unfamiliar place, or person.It turns out that a kind of projection.What happens?The human brain all programs in advance?
how to conduct experiments?
To better understand what is at stake, let's learn how scientists in Colorado conducted the study.So, they chose a few subjects, provided them with pictures with images of famous personalities from different spheres, famous people, a variety of attractions, which are known to everyone.
Thereafter, subjects were asked to voice the image name and the names of places or people's names.At that moment, when they gave their answers, the researchers measured their brain activity.It was found that the hippocampus (which we discussed above) was in a state of activity even for those respondents who did not know even approximately correct answer.After the event people are told that when looking at the picture and understand that this person or place is unfamiliar to them, in the minds of certain associations appeared that they had already seen.As a result of the experiment, the scientists decided that if the brain is capable of additional associations known to completely unfamiliar situation, then this is the explanation of the effect of deja vu.
Another hypothesis
As we have said, there are several versions about what deja vu is and why it occurs.According to this hypothesis, the effect refers to the manifestations of so-called false memory.If the brain malfunctions occur in certain areas, it begins to take over all the unknown already known.Experts believe that a false memory "works" is not, in any age, her experience has the peaks of activity - from 16 to 18 years and from 35 to 40.
first surge
first peak of activity of false memory, scientists explain the fact that adolescencevery emotional period is expressed in all respects.People at that time quite dramatically and sensitive to current events.The lack of great experience also plays a role in why there is deja vu.It is a sort of compensation, hint.The effect is manifested when a teenager needs help.In this case, the brain "is drawn" to false memory.
second surge
second peak falls exactly on the midlife crisis.This is a crucial period in life when they feel nostalgia for the past, there are certain regret or wish to return to the former years.Here again, the brain comes to the aid, he refers to the experience.And it gives us the answer to the question: "Why is deja vu?".
Viewpoint psychiatrists
I must say that this hypothesis is significantly different from previous ones.Doctors had no doubts that the value of deja vu can not be ignored, because it is a mental disorder.And the more effect is, the more serious the situation is.They argue that over time it will grow into a long hallucination, dangerous for both the man and for his environment.Doctors after studies observed that this phenomenon is mainly in people suffering from all kinds of memory defects.Parapsychologists do not rule out another version.So, they tend to associate déjà vu with reincarnation (transmigration of the soul after death into another body).Of course, modern science does not accept this version.
What other opinions on this?
For example, in the 19th century German psychologists have explained the effect of elementary, as a result of simple fatigue.The fact is that those parts of the brain that are responsible for consciousness and perception, are not consistent with each other, ie crashes.And it is expressed in the form of the effect of deja vu.
physiologist from America Burnham argued the opposite.For example, he believed that the phenomenon in which we find certain objects, actions, people associated with the total relaxation of the body.When a person is fully rested, his mind free from problems, experiences, thrills.That's when the brain can perceive everything much faster.It turns out that the subconscious is already experiencing things that can happen to a person in the future.
Many people believe that they know how there is deja vu, thinking that this is the result of dreams that we once saw.True or not - it's hard to say, but such an idea exists among scientists.The subconscious mind is able to record the dreams that we have seen, even many years ago, and then play them (many consider this as predicting the future).
Freud and Jung
To better understand what is deja vu, let us remember the movie about Schuricke when he was so engrossed in reading the synopsis, he had not noticed any of his being in someone else's apartment or cakes with mustard, no fanor the girl herself Lida.But when he appeared there have realized he experienced what we call the effect of deja vu.Just in this case, the viewer knows that the Shura've been here before.
Sigmund Freud once described this state as a real memory that was "erased" in the mind under the influence of various unfavorable factors.It could be a trauma or experience.Some force made a certain way to move to the subconscious mind, and then there comes a point at which the "hidden" image suddenly comes out.
Jung also linked with the effect of the collective unconscious, in fact, the memory of our ancestors.And this brings us back to biology, reincarnation and other different hypotheses.
turns out, no wonder they say that the world is interconnected.Perhaps, in this case, too, it makes no sense to look for the only correct answer, if only because there is no guarantee that it exists?It is no wonder that even the scientists have put forward the version that can be fully declare and prove to the world that the answer is found.
In any case, do not be afraid if you occur this effect.Think of it as a hint as something akin to intuition.Remember the main thing: if the phenomenon was something really scary or dangerous, you would have already knew exactly.
