Deja Vu，来源于法语，中文一般翻译为：一种似曾相识的感觉。也就是觉得曾经经历过，估计这种感觉很多人都有过吧？

Wikipedia上Deja Vu的定义为：

The term déjà vu (French:"already experienced", also called paramnesia) describes the experience of feeling that one has witnessed or experienced a new situation previously. The term was created by a Frenchpsychicresearcher,Emile Boirac (1851–1917) in his book L’Avenir des sciences psychiques (The Future of Psychic Sciences), which expanded upon an essay he wrote while an undergraduate French concentrator at theUniversity of Chicago. The experience of déjà vu is usually accompanied by a compelling sense of familiarity, and also a sense of "eerieness" or "strangeness" or "weirdness". The "previous" experience is most frequently attributed to a dream, although in some cases there is a firm sense that the experience "genuinely happened" in the past.

解释为：

In recent years, déjà vu has been subjected to serious psychological and neurophysiological research. The most likely candidate for explanation, according to scientists in these fields, is that déjà vu is not an act of "precognition" or "prophecy" but is actually an anomaly of memory; it is the impression that an experience is "being recalled" which is false. This is substantiated to an extent by the fact that in most cases the sense of "recollection" at the time is strong, but any circumstances of the "previous" experience (when, where and how the earlier experience occurred) are quite uncertain. Likewise, as time passes, subjects can exhibit a strong recollection of having the "unsettling" experience of déjà vu itself, but little to no recollection of the specifics of the event(s) or circumstances they were "remembering" when they had the déjà vu experience, and in particular, this may result from an overlap between the neurological systems responsible for short-term memory (events which are perceived as being in the present) and those responsible for long-term memory (events which are perceived as being in the past).

今天晚上吃饭，外国同事则给了我另一番解释。人脑中负责控制Emotion的Brain和控制Logic的Brain的速度出现了及短暂的不一致，控制Emotion的Brain在很短的一个时间片比控制Logic的速度快，就会造成这种情况。Discovery中曾经有人两个脑子Speed不一致的病例，比如去超市买东西，在结帐的时候才发现买了很多自己根本不该买，又无法付帐的东西。

人脑真是复杂，最近在做一些试图仿照人脑进行某些数据处理的工作，开始重新学习数学、统计学，过程真是痛苦，希望光明就在前方吧。
