Seems like we have ...

Researchers believe that the key to deja vu has been found - an odd feeling when someone thinks that it seems to have seen this somewhere.

Experiments show that deja vu can be created independently without evoking memories. Recognizing a familiar scene and object is thought to release two processes in the brain.

First, the brain reviews the memory store to find out whether the context has been observed earlier. If so, an independent part of the brain will identify the same scene or object.

To test this hypothesis, the team at the University of Leeds in the UK gave volunteers a look at 24 common words, then hypnotized them.

These hypnotized people will be "injected" in the head that when they see a word in the red frame, they will feel the word familiar, although they do not remember to see the last time.

But when they see a word in the green box, they will think that the word belongs to the 24 word list.

Participants then regained consciousness and watched a series of words in different color frames. Some words are not on the old list and are tagged with red or green frames.

10 of the volunteers said they had a strange feeling when they saw the strange word in the red frame, 5 others said that this feeling is exactly deja vu.

Researcher Akira O'Connor said the results revealed the cause of deja vu and the working mechanism of human memories . "It shows that it is possible to separate these two processes and create the deja vu phenomenon," O'Connor said.

Previous research has shown that deja vu may originate from the brain called the temporal lobe. Some people with epilepsy in the temporal lobe often have deja vu phenomenon. French scientists have also found that electrical stimulation in the temporal lobes can create a feeling of familiarity with everything people encounter.
