Need a Clue on Déjà Vu?

Déjà vu is the feeling you get when you think you have already experienced the situation you are in. It can be described as feelings of having already been to a place, met a certain person, or completed a specific act.

What's Going On In The Brain?

Because déjà vu occurs to all different types of people and is over so quickly, it is difficult to study and there are many guesses as to why it occurs. Different types of scientists and psychologists have different theories as to why this occurs, ranging from wishful thinking to a mix up in the brain between past and present, and past-life experiences. Studies had found that when the medial temporal lobe was disrupted could cause déjà vu. When the rhinal cortex (which contains structures involved in memory and sensory processing) was stimulated, déjà vu would occur. French researchers found that a déjà vu episode would occur when the neural firing from the rhinal cortex, the hippocampus (involved in memory formation), and amygdala (involved in emotion) were all in sync.

Research and Psychologists

Anne M. Cleary is a psychologist who studied déjà vu. She held experiments that found out what parts of situations could produce feelings of familiarity. She had people study a list of random words. During a word recognition test, some of the words on the test resembled the earlier words in the way they sounded, and the volunteers reported a sense of familiarity for the new words, even when they could not remember what words had reminded them of those words. Other research had found that people would feel feelings of familiarity with situations that looked slightly similar to places they had been before.
