Deja Vu Mystery

The Mystery of Déjà vu

Have you ever been somewhere, and had the feeling that you've been there before? Well the answer is Deja Vu. How is it caused? Well there are many opinions about Deja Vu, and I am going to provide a resonable amount of information to support this thesis with 3 different theorems.

The causes of Deja Vu are still widely unknown. In practice, there usually are two components: an element that is similar to an earlier experience encountered by the participant without being a major component of the earlier event, and a degree of strong emotion, including potentially psychosis, concerning the possibility of the event. Thus, while seeing a piece of bread wouldn't likely cause Deja Vu concerning a sandwich eaten five

There are several possible explanations for what is occurring during a déjà vu experience. One possibility is simply the occasional mismatch made by the brain in its continuous attempt to create whole sensational pictures out of very small pieces of information. Looking at memory as a hologram, only bits of sensory information are needed for the brain to reconstruct entire three-dimensional images. When the brain receives a small sensory input (a sight, a smell, a sound) that is strikingly similar to such a detail experienced in the past, the entire memory image is brought forward. The brain has taken the past to be the present by virtue of one tiny bit of sensory information. It does not, however, seem to provide sufficient answers to individual (even my own) accounts of déjà vu, where the memory image pulled up is not necessarily from a true past event.

Other scientists would say other effects that cause Déjà vu such us Robert Vaessen stating that it's caused by a chemical imbalance in the brain. When events are occurring in the present, our brain processes the activity in a part of the brain called the amygdala. Deja vu occurs when present events are processed in a part of the brain typically used to recall past memories. The parahippocampal cortex, which is very closely connected to the hippocampus. Because the event is processed in the parahippocampal cortex, it has a past 'flavor' associated with

Then, when we are able to focus on what we are doing, those surroundings appear to already be familiar to us even when they shouldn't be.

The Hologram theory by Dutch psychiatrist Herman Sno proposed the idea that memories are like holograms, meaning that you can recreate the entire three-dimensional image from any fragment of the whole. The smaller the fragment, however, the fuzzier the ultimate picture.
Déjà vu ... happens when some detail in the environment we are currently in (a sight, sound, smell, et cetera) is similar to some remnant of a memory of our past and our brain recreates an entire scene from that fragment.

Robert Efron tested an idea at the Veterans Hospital in Boston in 1963 that stands as a valid theory today ; the Dual Processing Theory.
He proposed that a delayed neurological response causes déjà vu.
Because information enters the processing centers of the brain via more than one path, it is possible that occasionally that blending of information might not synchronize
