Déjà vu and the Brain :: Biology Essays Research Papers

UGH I Just Got the Creepiest Feeling That I Have Been Here Before Dj vu and the Brain, Consciousness and SelfWe have all some get wind of a feeling, that comes over us occasionally,, of what we are saying and doing having been said and make before, in a remote time - of our having been surrounded, dim ages ago, by the selfsame(prenominal) faces, objects, and circumstances - of our knowing perfectly what will be said next, as if we suddenly remember it (Dickens in David Copperfield - chapter 39 (1)) It happens to me and it has probably happened to you. It is sudden and fleeting, difference as unexpectedly as it came. While the experience is striking in its clarity and detail, it is difficult to recapture or recount. Generally, it is left unexplained and is expound in a vague sense, often simply as, Wow, I alone got the strangest dj vu. Because it is so difficult to research and seems to have no deleterious effects on daily and long-term nervous remains function, dj vu has been left largely to the wayside of neurobiological investigation. In all of its ambiguity, dj vu is still a perplexing phenomenon that has not yet been fully explained. The value of truly understanding the source of dj vu and its circuitry is in uncovering one of the many keys to the role of the certain self in the functioning of the brain. What is dj vu and how does it work? Dj vu is considered a common phenomenon. Surveys show that about one tertiary of the population has had the most common form of dj vu sensations (1). due to the subjective and often indescribable nature of the associated feelings, it has been difficult, to determine who is actually experiencing dj vu. In general, however, dj vu is any number of hard-to-explain sometimes upsetting occurrences of unexpected recognition, in which the person involved has trouble identifying an root word for the events and/or places which seem so strangely and intensely familiar (1). Dj vu has been defined as familiarity without co nsciousness (13). While the situational cues of a dj vu are familiar, there is a definite lack of awareness about the specific source of the memory. Arthur Funkhouser (1) defines three types of dj vu in an attempt to more clearly delineate between associated, but different, neurologic experiences. These are dj vecu (already experienced), dj senti (already felt) and dj visit (already visited).
