What Is Déja Vu?
It means Already Seen!
There are also three different types of Deja Vu:
- Déja Veçu - already experienced or lived through
- Déja Senti - already felt
- Déja Visite - already visited
The Brain
Other parts of the brain that are affected:
- temporal lobes/amygdala - concerned with the past
- frontal lobes - concerned with the future
- underlying, intermediate portions (the limbic system) - concerned with the present
Other Theories
There are unlimited amounts of different theories as to why we experience deja vu, but here are a few of them:
2. Another theory suggests that deja vu is caused by glitches when our brain processes information. Specifically, these glitches occur in the information that passes through perception and memory. This theory is supported by people who suffer from epilepsy.
3. According to psychological and neuropsychological research, deja vu is an anomoly, or something that deviates from what is standard, normal, or expected, of memory. The sense of recollection is at the time stronger than the time o experience.
4. Due to the exploration of vision, it is also believed that one eye records faster than the other. This creates the strong recollection of what is supposedly "already seen".
The Research and Psychologists
Emile Boirac was the first person to use the term 'deja vu' in his book "L'Avenir des Sciences Psychiques" . However, he did not research it in depth; and Sigmund Freud is credited with theorizing these experiences. From these ideas, scientists used the theory of paramnesia to explain deja vu for most of the 20th century.
Experiment
The most famous experiment dealing with deja vu was conducted by psychologist Wilder Penfield in 1955. Within his experiment, he electrically stimulated the temporal lobes, and found that 8% of his subjects experienced some type of memory. He, however, thought he elicited actual memories. Today, it is concluded from his experiment he may have instead elicited hallucinations and the first examples of artificial deja vu.
