Moments of déjà vu

Moments of déjà vu, during which you feel things you think you’ve experienced before, can be disturbing. For some time this phenomenon was thought to be caused by the brain creating false memories, but new laboratory experiments offer a different explanation. By using brain scanning techniques, scientists have discovered that the frontal areas of the brain which are involved in decision making are active when a person experiences déjà vu. They suggest that déjà vu may be the process by which the brain occasionally checks its memory banks.
