Deja Vu

We chose this topic because we are interested to see what happens in the brain when Deja Vu occurs. This research will help us learn more about the topic and will help other people if they are also interested in learning about how it works.

What is it?

Deja Vu is the feeling or sensation that you have been somewhere or done something before you actually do it or while you are doing it.


Research on deja vu falls into two main categories: observational studies and experimental studies. In observational studies, researchers measure features of the deja vu experience and look for patterns and links in the results. Observational studies told us that young people have more deja vu experiences than older people.

Whats going on in the brain???

All theories of memory acknowledge that remembering requires two cooperating processes: familiarity and recollection. Familiarity occurs quickly, before the brain can recall the source of the feeling. Conscious recollection depends on the hippocampus and prefrontal cortex, whereas familiarity depends on regions of the medial temporal cortex.

Intresting Facts

Almost all deja vu is linked back to dreams that were so vivid the brain turns them into memories.
