Why does your brain sometimes insist that a brand new experience is old news?
In short: The sensation of déjà vu is a familiar yet mysterious glitch in perception. This video explores the psychological and neurological theories behind why we feel we have lived through a moment before, despite knowing it is happening for the first time.
Déjà vu is a phenomenon where a current, novel experience feels like a memory of a past event. While over 40 distinct theories have been proposed to explain this occurrence, modern research has begun to narrow the field.
By utilizing neuroimaging and the principles of cognitive psychology, researchers are working to isolate the specific brain mechanisms responsible for this feeling. The study of déjà vu bridges the gap between how we process new information and how our minds construct the sense of familiarity.
