Scientists have found that behind the state of deja vu

Many people are familiar with the feeling that the situation in which they find themselves for the first time, it seems strangely familiar. At the same time they realize that they have never been in this place or in the circumstances. This phenomenon is called "deja vu."

"What's really amazing is that the sense of a familiar situation accompanied by understanding that the current situation should in fact be entirely new for the people" — says one of the study's authors, Chris Martin (Chris Martin). But as one and the same experience can provoke such different feelings?

Unfortunately, the state is not enough studied and described in scientific terms. One of the difficulties of studying déjà vu is that it is transient and can not play back in the lab.

Chris Martin and psychology professor Stefan Köhler (Stefan Kohler) could shed some light on this amazing phenomenon. They conducted a study involving a group of rare neurological patients with déjà vu is an early sign of the coming attack. Due to prolonged disease of the brain in the majority of patients diagnosed with "temporal lobe epilepsy" there is a slight memory loss. This was noted even at times when patients do not have seizures.

Relying on this relationship, S. Kohler and his colleagues began to look for behavioral indicators of deja vu, addressing the subjects were requested to perform certain tasks to help investigate a feeling familiar situation.

Scientists have discovered a pattern of behavior that clearly distinguishes the people in a state of deja vu from the rest. Unlike the others, patients with deja vu yet aware that feeling familiar with the situation are out of season and were able to recall the pertinent information about the actual events took place in the past.

These findings have enabled a new way to look at the psychological mechanisms that lead to the fleeting feeling of deja vu.
