DéJa-Vù

All of us at some point of time have had experienced Deja-vu. It isthat shadowy feeling you get when a situation seems familiar. A scene in a restaurant plays exactly as you remember, the world moves like a ballet you choreographed , but the sequence can not be based on a past experience because you have never eaten here before. This the first time you have had clams,so what is going on?

Unfortunately there is no one single explanation for Deja-vu. The experience is brief and occurs without notice, making it nearly impossible for scientist to record and study the phenomenon.Scientists cannot sit around and wait for it to happen to them – this could take years. It has no physical manifestations and in studies it is described by the subject as a sensation or feeling. Because this lack of hard evidence , there has been surplus of speculations over the years. Since Emile Boriac introduced Deja-vu as aFrench term meaning “ already seen”. More than forty theories attempt to explain this phenomenon since then. Still, recent advancements in neuroimaging and cognitive psychology narrow down the field of prospects.The threemost used theory forexplaining this phenomenon are namelydual processing,hologram theory and divided attention.While all of these threetheories share the common feature of Deja-vu, none of them propose to be the conclusive source of the phenomenon. We are still waiting for researchers and inventors to come up with new ways to capture this fleeting moment, we could study the moments then all by ourselves, after all moststudies of Deja-vu are based on first-hand experiences and accounts. The next time you get Deja-vu, take a moment to think about it, have you been distracted, is there a familiar object somewhere? Is your brain acting slow or is it something else!!!!
