GMAT閱讀機經(jīng)整理：大腦神經(jīng)delay.

　　3月2日換庫后，小編為大家整理這個月的GMAT閱讀機經(jīng)，這篇GMAT閱讀機經(jīng)是關(guān)于大腦神經(jīng)delay的文章，考生朋友可以看看，下面的內(nèi)容為考古內(nèi)容，分享給大家，希望對大家有所幫助，文中觀點僅供參考。

　　[V1]

　　關(guān)于人看東西，然后通過神經(jīng)元傳輸給大腦，因為傳輸?shù)穆窂讲灰粯?，所以速度不一樣。一般來說有1/10秒的delay什么什么的，記不起來了。應(yīng)該是perception, neuron，brain啥的

　　[V2]

　　閱讀有一個講視覺神經(jīng)的反應(yīng)問題， 說從看到東西到反應(yīng)有一個過程，大概十分之一秒，但是這個已經(jīng)足以用來生存了， 這個是不是之前說過?第一段是說人的大腦梳理不同的信息like sound images， 用不同的tunnelL和parts,

　　第二段就集中將視覺神經(jīng)怎樣把信息從終端(vertex)傳到大腦， 然后又傳回眼睛。。。

　　就是一個cycle的過程。說這個中間有delay，但是時間很短，十分之一秒。所以足夠了。

　　但是中間還提到神經(jīng)元的傳播有多種途徑，有Lightning， 還有其他兩種，記不清了

　　[V3]

　　第一篇就是JJ里的那個1/10 delay。 實際上是第一段說因為visual cortex要同時處理不同的視覺信號，而這些信號傳遞的速度不同 第二段就是講怎么處理信號---VC等最慢的信號傳遞到時再一起呈現(xiàn)給大腦--這一等就是1/10s，但是這種延遲實際上是不利于survival的。最后結(jié)尾時作者說1/10s是能活命的最長delay時間了。

　　感覺 得兒意 概括了部分細節(jié) 但是在第二段的時候段意有點偏離啊～總共兩段 不長的。

　　[V4]

　　還有道閱讀是狗狗里有的大腦視覺神經(jīng)處理信心傳遞中的delayed的問題的。

　　第一段好像沒有題就不記得了...第二段說人腦將外面的信息處理后最終輸送到vertex...后面有一句話忘記說什么了。但是有道題就是選就是這句話的重述...然后說人腦會等輸送最慢的信息到達，等待的時間大概是1/10...將過去的事情聯(lián)系起來就像現(xiàn)在剛發(fā)生一樣。人腦的這個功能是有利于survival的...然后不記得了...

　　[V5]

　　高亮題，樓主個人認為題中說的那個survive并不是說delay讓人們survive，而是說的是最多延遲10分之1，聽到的東西才能survive。但是我的語法分?jǐn)?shù)不高，所以，只是個人觀點。

　　[V6]

　　第二篇是說人大腦的，兩段。

　　第一段說人眼觀測到的圖像傳送到大腦是要時間的

　　第二段說研究

　　題目忘了

　　[V7]

　　第三篇是人們視覺反應(yīng)機制的延遲現(xiàn)象，這個機經(jīng)里有了太著急了沒看完~

　　第一段意思是人的視覺反應(yīng)需要對環(huán)境等所看到的事物有映射，所以視覺對人腦中的反射區(qū)域有更高的要求;

　　第二段在講也許有一個延遲，中間三句重點看(題目需要理解這個延遲的原理)，好像結(jié)尾就是把全文基調(diào)定一下，說這種延遲是positive的立場~

　　[V8]

　　還中了大腦延遲的，雖然有寂靜，但感覺這篇我做的不好。有細節(jié)題，我記得有一句話，波折號后面幾個單詞，加逗號would…這里有考點，而我當(dāng)時沒有揣摩清楚用意。大家好好讀讀。

　　閱讀材料：

　　Future perception(這段有點像文章的第三段，講1/10 second delay的)

　　Researcher Mark Changizi of Rensselaer Polytechnic Institute in New York has a more imaginative take on optical illusions, saying that they are due to a neural lag which most humans experience while awake. When light hits the retina, about one-tenth of a second goes by bore the brain translates the signal into a visual perception of the world. Scientists have known of the lag, yet they have debated how humans compensate, with some proposing that our motor system somehow modifies our movements to offset the delay.

　　Changizi asserts that the human visual system has evolved to compensate for neural delays by generating images of what will occur one-tenth of a second into the future. This foresight enables humans to react to events in the present, enabling humans to perform rlexive acts like catching a fly ball and to maneuver smoothly through a crowd.[5] Illusions occur when our brains attempt to perceive the future, and those perceptions don&apost match reality. For example, an illusion called the Hering illusion looks like bicycle spokes around a central point, with vertical lines on either side of this central, so-called vanishing point. The illusion tricks us into thinking we are moving forward, and thus, switches on our future-seeing abilities. Since we aren&apost actually moving and the figure is static, we misperceive the straight lines as curved ones.

　　Changizi said:

　　"Evolution has seen to it that geometric drawings like this elicit in us premonitions of the near future. The converging lines toward a vanishing point (the spokes) are cues that trick our brains into thinking we are moving forward—as we would in the real world, where the door frame (a pair of vertical lines) seems to bow out as we move through it—and we try to perceive what that world will look like in the next instant."[5]

　　Changizi said:(這段與原文內(nèi)容有點相關(guān))

　　"Evolution has seen to it that geometric drawings like this elicit in us premonitions of the near future. The converging lines toward a vanishing point (the spokes) are cues that trick our brains into thinking we are moving forward—as we would in the real world, where the door frame (a pair of vertical lines) seems to bow out as we move through it—and we try to perceive what that world will look like in the next instant."[5]

　　以上就是關(guān)于大腦神經(jīng)delay這篇GMAT閱讀機經(jīng)的全部內(nèi)容，考生可以有選擇的看看，機經(jīng)雖好，但是也要適度喲。最后祝大家都能考出好成績。
