GMAT阅读机经整理：大脑神经delay.

　　3月2日换库后，小编为大家整理这个月的GMAT阅读机经，这篇GMAT阅读机经是关于大脑神经delay的文章，考生朋友可以看看，下面的内容为考古内容，分享给大家，希望对大家有所帮助，文中观点仅供参考。

　　[V1]

　　关于人看东西，然后通过神经元传输给大脑，因为传输的路径不一样，所以速度不一样。一般来说有1/10秒的delay什么什么的，记不起来了。应该是perception, neuron，brain啥的

　　[V2]

　　阅读有一个讲视觉神经的反应问题， 说从看到东西到反应有一个过程，大概十分之一秒，但是这个已经足以用来生存了， 这个是不是之前说过?第一段是说人的大脑梳理不同的信息like sound images， 用不同的tunnelL和parts,

　　第二段就集中将视觉神经怎样把信息从终端(vertex)传到大脑， 然后又传回眼睛。。。

　　就是一个cycle的过程。说这个中间有delay，但是时间很短，十分之一秒。所以足够了。

　　但是中间还提到神经元的传播有多种途径，有Lightning， 还有其他两种，记不清了

　　[V3]

　　第一篇就是JJ里的那个1/10 delay。 实际上是第一段说因为visual cortex要同时处理不同的视觉信号，而这些信号传递的速度不同 第二段就是讲怎么处理信号---VC等最慢的信号传递到时再一起呈现给大脑--这一等就是1/10s，但是这种延迟实际上是不利于survival的。最后结尾时作者说1/10s是能活命的最长delay时间了。

　　感觉 得儿意 概括了部分细节 但是在第二段的时候段意有点偏离啊～总共两段 不长的。

　　[V4]

　　还有道阅读是狗狗里有的大脑视觉神经处理信心传递中的delayed的问题的。

　　第一段好像没有题就不记得了...第二段说人脑将外面的信息处理后最终输送到vertex...后面有一句话忘记说什么了。但是有道题就是选就是这句话的重述...然后说人脑会等输送最慢的信息到达，等待的时间大概是1/10...将过去的事情联系起来就像现在刚发生一样。人脑的这个功能是有利于survival的...然后不记得了...

　　[V5]

　　高亮题，楼主个人认为题中说的那个survive并不是说delay让人们survive，而是说的是最多延迟10分之1，听到的东西才能survive。但是我的语法分数不高，所以，只是个人观点。

　　[V6]

　　第二篇是说人大脑的，两段。

　　第一段说人眼观测到的图像传送到大脑是要时间的

　　第二段说研究

　　题目忘了

　　[V7]

　　第三篇是人们视觉反应机制的延迟现象，这个机经里有了太着急了没看完~

　　第一段意思是人的视觉反应需要对环境等所看到的事物有映射，所以视觉对人脑中的反射区域有更高的要求;

　　第二段在讲也许有一个延迟，中间三句重点看(题目需要理解这个延迟的原理)，好像结尾就是把全文基调定一下，说这种延迟是positive的立场~

　　[V8]

　　还中了大脑延迟的，虽然有寂静，但感觉这篇我做的不好。有细节题，我记得有一句话，波折号后面几个单词，加逗号would…这里有考点，而我当时没有揣摩清楚用意。大家好好读读。

　　阅读材料：

　　Future perception(这段有点像文章的第三段，讲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:(这段与原文内容有点相关)

　　"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]
