Finally! Simple and clear explanation of deja vu

Deja vu always occur suddenly and lasts a few seconds. But sometimes the impression can be so strong that it remains in the memory for years. Someone connects the phenomenon of déjà vu with dreams, someone who expresses more extravagant theory about the noosphere and past lives. But the truth is that only one EEG recording is able to put everything in its place.

The website publishes an article in which the phenomenon of deja vu is described is accessible and understandable.

The only problem is that the feeling of deja vu can't be artificially evoked, and it is very difficult to study. But a pure accident that happened a few years ago with Russian scientists, letting them see the EEG to test the brain during the feeling of déjà vu. The reality was much more prosaic than mystical guesswork.

There is such a region in the brain called parahippocampal gyrus". It is responsible for the fact that we understand what information comes to us from memory, and which reflects what happens to us in reality. And in those rare situation when in this part of the brain fails, we have a feeling of deja vu.

For simplicity, imagine our brain as a large, zaprjanova city. When everything in it works as it should, the truck with the new information is going to be the most obvious short, and most importantly direct route from point a to point B. From the sense organs to specific brain structures responsible for processing new information.

But if this route to the brain for some reason there is a "stopper", the truck has to go to bypass, alternative route. Just through those areas of the brain in which we store our memory. In particular — through the right temporal lobe. As a result, when the signal, after wandering the winding streets of the brain still gets to goal, fails. In a matter of seconds, the brain ceases to perceive the information that they brought this truck is like new, only what is seen by eye. And is it something received from long-term memory. This is why we begin to feel that place in which we were, or an event that happens to us, we are already familiar.

So no otherworldly romance, no past lives and lucid dreams to the phenomenon of deja vu there. This is a common intermittent failure of the brain. A computer glitch if you want.
