JAKARTA, NETRALNEWS.COM - Ever experienced a sense of deja vu? In French, this word means "already seen". Deja vu happens when we feel a sensation as if we have experienced something before in the past.
So, what causes deja vu exactly?
Psychology expert Professor Paul Reber from Northwestern University says deja vu happens because parts of the brain called the hippocampus and the prefrontal cortex work too fast, causing both parts to slightly be out of sync, triggering the sensation of deja vu, as reported by VOA.
On the other hand, psychologist Professor Anne Cleary from Colorado University said deja vu is a condition in which memory does not really work properly. Because we do not have a specific experience, we will feel a very familiar sensation with the situation that is happening at the time.
Cleary's opinion is supported by a study conducted at Leeds University in 2005 in the United Kingdom that stated those who experience deja vu were already suffering some sort of light damage in the frontal and temporal parts of their brains
