Dejavu is ...


first time the term "déjà vu» (déjà vu - already visible) was used by the French psychologist Emil Buarakom (1851-1917) in his book "The Psychology of the Future".Prior to that, it is a strange phenomenon described as "false recognition" or "paramnesia" (memory deceptions with impaired consciousness), or else "promneziya" (a synonym of deja vu).

There are also several similar phenomena: deja vecu ( "already experienced"), deja entendu ( "already heard"), jamai
s vu ( "never had seen").The effect is the opposite of deja vu - zhamevyu, typical for him, when a man does not know his familiar things.This effect is characterized by memory loss that this condition occurs quite suddenly, for example, your friend is talking to you, you may suddenly seem completely unfamiliar man.All the knowledge that you have about this person, simply disappear.But zhamevyu phenomenon is much rarer than deja vu.

scientists is difficult to study the effects of the data, as they in turn relate only to human feelings and emotions.From the point of view of the physiology of the cause of all these phenomena is in the brain.It is very difficult to experiment in this field, as even the slightest intervention can make a person disabled, deaf, blind, paralyzed or worse.




study of "deja vu»


scientific study of the phenomenon of deja vu proceeded not so active.In 1878, the German psychological journal, it was suggested that the feeling of "already seen" occurs when the processes of perception and awareness, which mainly occur at the same time, in a particular case rassoglasovyvayutsya into force, for example, fatigue.This explanation has become one of the sides of the theory, which, in turn, suggests the cause of deja vu in the brain congestion.To say in other words, the deja vu occurs when a person is very tired, and there are peculiar failures in the brain.

Judging from the other side of the theory, the effect of déjà vu - this is the result of good brain rest.In this case, processes will occur in a few times.If we are able to handle one or the other way quite quickly and easily, our brain subconsciously interpret this as a signal that we have seen previously.As he wrote in 1889, American physiologist William H. Burnham, who was the author of this theory - "when we see a strange object, its unfamiliar appearance is largely due to the difficulty with which we face in the knowledge of its characteristics.But when the brain centers finally rest, perception strange scene may seem so easy that kind happening already seem familiar. "

later for the study of the effect of deja vu took Sigmund Freud and his followers.Scientists believe that a sense of "déjà vu" occurs in humans as a result of spontaneous resurrection in his immediate memory subconscious fantasies.As for Freud's followers, they in turn believed that déjà vu is the result of the fight, "I" with "It" and "Super - I am."

Some people attribute his déjà vu that previously unfamiliar places or things they have seen in a dream.This version is also not ruled out by scientists.In 1896, Arthur Allin, professor of psychology at the University of Colorado in Boulder, put forward the theory that the effect of deja vu - a reminder of the fragments of forgotten dreams us.Our emotional reactions to the new image can play a false sense of recognition.The effect of deja vu occurs, then when suddenly our attention briefly distracted during our first acquaintance with the new image.

also characterize the phenomenon of deja vu even as an expression of false memory, that is in the brain, or to be more precise, in its particular areas, there is a certain failure, and it begins to take unknown to the known.For the so-called false memory characteristic such aging periods, when the activity of this process are most pronounced - from 16 to 18 and from 35 to 40 years.

splash during the first period is due to emotional expressions of adolescence, the ability to overreact and even dramatically react to certain events, for lack of experience.In such a case, the person requesting assistance from the fictitious experience, getting it directly from a false memory.As for the second peak, it in turn, also falls on the watershed age, but this is a midlife crisis.

At this stage of deja vu is moments of nostalgia, any regrets about the past, the desire to return to the past.This effect may also be called blende memory because memories can not be true, as alleged, the past appears as the ideal time, when it was still beautiful.


In 1990, a psychiatrist from the Netherlands, Herman Sno has been suggested that memory traces are stored in the human brain in the form of some holograms.The hologram of the pictures is different in that each piece of the hologram carries all the information that is necessary to restore the whole image.The fragment of a smaller, respectively, the reproduced picture is vague.In theory Sno arising feeling of déjà vu is obtained when some small part of the situation quite closely coincides with a certain piece of memory, which in turn conjures up a vague picture of a past event.

Pierre Glur, neuropsychiatrist, in the 1990s conducted experiments, and stubbornly insisted that the memory has special "recovery" systems (retrieval) and "recognition» (familiarity).In his work, which was published in 1997, he argued that the déjà vu phenomenon manifests itself in quite a few moments.When our system of recognition is activated, and the recovery system - no.Other scholars insist that the recovery system can not be turned off completely, but it may just be misaligned, which in turn resembles the theory of fatigue, which was launched much earlier.


physiological explanation


But, despite no matter what, the researchers were still able to find out in what part of the brain involved in the process at a time when a person feels a sense of deja vu.It is worth noting the fact that different parts of the brain are responsible directly for the different memory options.The frontal part is responsible for the future, for the past temporal and basic - intermediate - responsible for our present.When all these parts of the brain do their usual work when consciousness is normal, the feeling that something is going to happen, you may be only in the case, when we think about the future, we worry about him, warn him or to buildplans.

But not so simple as we would like.In our brain, there is an area (the amygdala), which directly sets the emotional 'tone' to our perception.For example, when you conduct a conversation with someone and see how changes in your interlocutor's expression, namely the amygdala in a matter of seconds gives a signal about how it should react to it.In fact, the duration of neurological concepts of "real" is so short that we do not experience as much as we remember.

short memory stores information for several minutes.For this, in turn, corresponds to the hippocampus (hippocampus): memories, which in turn are associated with a particular event, are scattered in different sensory centers of the brain, but they are connected in a certain order gippokamusom.In particular, there is still a long-term memory, which is located on the surface of the brain, along the temporal part.

In fact, it is fair to say that the past, present and future exist in our brains, without having clear boundaries.When we experience something in the present, then we compare it with a similar past and already decide in the moment, to respond to what is happening in the near future.It was at this point, and include all the necessary areas of the brain.In the case where the connections between the short and long term memory too much, can be perceived as present and in the past this case, deja vu effect occurs.

As an explanation of this phenomenon can be involved, and the model of global comparisons, as they are called psychologists.A particular situation may sound familiar to a person, because it bears a strong resemblance to it stored in its memory of past events, or in the event that it has similarity with many held in the memory of the events.So you were in identical and quite similar situations more than once.Thus, your brain is summarized and compared the data memories, thus, I found a similar picture on them.


Reincarnation or reboot?


Many people are inclined to believe that déjà vu is some mysterious and even mystical roots.This happens due to the fact that scientists really can not explain why there is a deja vu.Parapsychologists explain deja vu theory of reincarnation, in that case, if the person lives more than one life, and more, he can recall some episodes of one of them.

ancient Greeks believed in reincarnation, even the early Christians, and quite famous Swiss psychologist Carl Gustav Jung, who, in turn, believed that living two parallel lives.One life - it is his, and the second - this is the life of the doctor, who lived in the eighteenth century.It should also be noted that a deja vu mentioned and Leo Tolstoy.

Tina Turner when she arrived in Egypt, suddenly saw quite familiar landscapes and objects, and recalled that at the time of the pharaohs, it was a friend of the famous Queen Hatshepsut.Something like that experienced and well-known singer Madonna during her visit to the Imperial Palace in China.

Many suggest that the "already seen" - this is the genetic memory.In this case, the awkward feeling of deja vu is explained as a remembrance of the ancestors of life.

Many psychologists believe that this phenomenon may be just a function of human self-defense.When we are in an awkward situation, or in a strange place to us, we will automatically begin searching for some familiar things or objects, this is done in order to somehow support your body at the time of psychological stress.

phenomenon of deja vu quite common.Specialists was established that 97% of people at least once, but experienced it.There were and are quite unique cases.When a person is experiencing a sense of deja vu almost every day.Basically this feeling to some extent accompanied by a slight sense of discomfort, but it can sometimes be intimidating.

psychiatrists also argue that frequently occurs deja vu may be a symptom caused by the temporarily-shared epilepsy.In many cases, it is not dangerous.In addition, some research has shown that deja vu can cause artificially or through hypnosis, or by means of electrical stimulation of the temporal lobes of the brain.

This surprising phenomenon is even trying to explain the physics.There is a sort of ecstatic conception, according to which the past, present and immediate future is happening at the same time.Our consciousness, in turn, can only perceive what we call "now".Physicists explain the phenomenon of deja vu, some failure in time.

Despite the fact that this phenomenon is strange and mysterious, since it is not for man is no danger, therefore, that every person can personally explain for yourself why this or that situation or object seem familiar to him.Perhaps you once saw him briefly on TV or just read about it in some book.
