Why Deja Vu?

I chose to research deja vu because of my curiosity towards the subject. Personally, I feel like I go through deja vu sometimes, so I thought it would be interesting if I got the chance to research it.
What is Déjà Vu?!

What is Deja Vu?

Deja Vu is a strong sensation that makes you feel like you had a certain experience or have in a specific place in another time, even if you have never experienced or been before. It is just a your brain reacting to a place or a memory that is familiar, but in reality is completely new.

The Brain

What is going on in the brain at this time?
During Deja Vu the brain feels a sense of fmilarity in a specific time, place, or experience which makes it think that it has seen this scenario before when it is actually completely new.

What parts of the brain are being used?
Studies have found that the sense of Deja Vu occurs in the rhinal corex which is involved with human episodic memory.

What parts of the brain are failing?
The brain is not failing it is simply just mixing up the familiarity of former experience.

Are there theories that address this topic?
Some scientists believe that Deja Vu can occur when there is a malfunction between long term and short term memory.

Other Interesting Stuff

Deja Vu is a French term that literally means "already seen".

It mostly occurs between the ages 15-25.

There have been cases found where people actually struggle with chronic Deja Vu which makes them believe they have experienced everything already so there is no reason to go to the doctor because they already know they have a disease or watch a tv show because they already know what happens.

The Research and Psychologist

There has been many researches on the subject of Deja Vu, but one in particular research was made by physiologist Anne M. Cleary. In her research she found out that Deja Vu is in correlation to recognition memory. Recognition memory is when you can pinpoint and exact memory or find yourself in familiarity. She found, when recognition memory occurs, people feel like they are going through Deja Vu.

Cleary ran some experiments in order to figure out what gives off a sense of familiarity. She gave a random list of word that sounded similar like "lady" and "eighty" to see if the test subject would feel familiarity which through her experiment, she found they did.
