I chose Deja Vu because i thought it would be an interesting topic to learn more about. I'm interesting in this topic because Deja Vu is experiencing something that you have already experienced. It could be similar smells and sights that bring back the familiar experiences.this research could help by giving a better understanding of how our brains remember things.

What is Deja Vu?

Deja Vu is an overwhelming feeling of familiar situations. Many people that have Deja Vu claim that they have already lived that moment and are reliving what has already happened. This could be brought back from sights or smells of an experience. For example, say you are driving down the streets of New York City for the first time, but when you are driving around you seem to realize an overwhelming feeling that you have already been there. Maybe you saw a restaurant, heard a conversation, or even people that you have seen before. All these things could bring that a sense of Deja Vu.

Questions on Deja Vu

Deja Vu is very random, this makes it hard for Neuro scientists to study. because of this many specialists can only take a hypothesis of what could happen to the brain; "Psychoanalysts may attribute it to wishful thinking; some psychiatrists cite mismatching in the brain causing us to mistake the present for the past."
It is concluded that the part of the brain reacting is the short-term to long-term memory receptors. This happens between the sensory input and memory-recalling output. Another hypothesis is that Deja Vu occurs when the brain fails at addressing time, the brain would take the experience and would "leak out" causing the brain to take the experience and put it in a past memory.

Importance?

Deja Vu is important to study because it could help us have a better understanding of how our brains take experiences and what, where, and how is stores the memory. understanding the lacking of grasping a moment could help us to better understand how our brains can mix up a situation and timing.

experiements and studies

There was an experiment conducted by Clearly, that tested familiarity-based recognition where participants were given a list of celebrity names. Later on, they were shown a collection of celebrity photographs; some photographs matched to the names on the list, while other photographs did not. The volunteers were told to identify the celebrities in the photographs and see how likely it was the celebrity’s names were on the list they had seen previously. Even when the volunteers were unable to identify a celebrity by photo, they had a sense of which names they had studied earlier and which they had not. They could not identify the reasoning for the familiarity with the celebrity, but they knew the celebrity was familiar to them. This experiment is a very good example for Deja Vu. Clearly Also studied and conducted an experiment on how words has meanings and how they are relevant. People were given a random set of words that sounded similar, only in the sense of sounds, for example they said they used "lady and Eighty". But, when they were given a new list of words, the volunteers had a a sense of Deja Vu for the words. Previous research has also shown that people feel familiarity when shown a visual fragment containing isolated geometric shapes from an earlier experience. This suggests that familiar geometric shapes may create the sense that an entire new scene has been viewed before.

Some interesting stuff on Deja Vu

Deja Vu is very interesting, how can the brain recall something from the past, that has never really occurred until then. Deja Vu is related to dreams, it is so interesting that our brains think that something occurs in real life that was really just a dream. How can our unconscious mind give a sense of consciousness and realism. A really interesting thing, is that some people believe that they could have special powers, because they are "predicting" or "predicted" the occurrence.
