CNN News: 未曾相見 但似曾相似

This next segment is going to trigger some serious deja vu. It`s not because we`ve covered it before, but if some reason you think we have, you`re probably in the age range when people experience deja vu the most often.

下面我們所要講的內容將會讓你產生似曾相識的感覺。這并不是因為我們曾報道過類似的內容，而是某些原因使你有這種感覺，那么你可能就處于人們經常經歷似曾相識感覺的年齡段。

Dr. Sanjay Gupta explores what it is exactly and the latest ideas from the medical community about why we experience it.

桑基·古普塔醫(yī)生研究了到底什么是“超時空效應”，以及醫(yī)學界關于有這種“超時空體驗”產生原因的最新思想。

You know, I suddenly have this feeling that I`ve told you this before.

現在我突然有了這種感覺是否我曾經報道過這則新聞。

You know, it happens without warning, the strange feeling that you`ve been there, done that, even though you know you never have.

有時候，感覺就是那么奇怪，毫無警示，奇怪的感覺就突然而至，及即使你知道自己從未做過此事，但是你就感覺自己曾經做過這件事。

The French have a word for it deja vu, meaning already seen.

在法語中有描述此現象的詞語“deja vu”(超時空效應)，這個詞語的意思是“已經見過”。

Now, while some claimed deja vu is a evidence of the paranormal such as past lives or alien abductions, other says we partially absorb scenes from television or movies to feel a sense of familiarity. It could be that our visual cortex is so fast at sending signals to our memory center, the hippocampus, that some believe the feeling of having seen it before is true, and it is true, but we saw it just a split second earlier.

現在，有部分人表示“超時空效應”證明了一些超自然現象，如過去的生活、外星人綁架，而另外一些人則表示我們曾從電視或者電影上看到一些場景，因此會產生似曾相識的感覺。也可能是我們的視覺皮質向記憶中心——海馬體發(fā)送信號速度很快，因此有些人認為這種似曾相識的感覺是真的，但是只不過是我們在瞬間之前見過此景，

About two-thirds of us experience deja vu, and oddly enough, it seems to happen most often between the ages of 15 and 25. So, it could be linked to the ongoing development of the brain. Scientists aren`t really sure. Because deja vu occurs randomly among healthy people, it`s been hard to study.

大約有2/3的人經歷過這種似曾相識的感覺，但是奇怪的是，似乎這種情境經常發(fā)生在15-25歲的人群之間。因此，這種感覺可能與大腦袋的經歷有關?？茖W家們也不是十分確定。因為，健康人群會毫無規(guī)律的產生這種“超時空效應”，所以很難進行研究。

Now, we do know deja vu occurs in the medial temporal lobe, that`s this area of the brain over here. That`s where the rhinal cortex, the part of the brain that helps us recognize familiar, interacts with the hippocampus, that`s the part of the brain that stores details of specific memories.

現在，我們知道這種超時空效應發(fā)生在內側顳葉，這同時也是大腦所在的區(qū)域。大腦中的頂葉皮層通過與海馬體相互作用，幫助我們識別熟悉的事物。而海馬體的作用是幫助儲存具體信息的細節(jié)內容。

Perhaps signals there get crossed, could be that brain circuits convulsed in an almost sort of seizure. And actually, you know what? That makes sense, because people with epilepsy do experience deja vu at the onset of the seizure. So, it`s now on epilepsy where most of today`s research is underway. In fact, neurologists have been able to trigger deja vu and people with epilepsy by stimulating, you guessed it, their medial temporal lobes.

也可能是交叉的信號，在驚厥中大腦回路震撼。實際上呢，這樣也講得通。因為癲癇病患者在發(fā)病的時候，也會產生“超時空效應”?，F在進行對癲癇病患者的研究。實際上，神經學家通過刺激癲癇病患者的內顳葉，引發(fā)了他們的似曾相識的效應。
