Background and Objective : Visual cortex is an essential center of vision . All sorts of visual information which transmit through visual path to visual cortex , causing the variation of potential in the neurons of the visual cortex , eventually makes visual sense .

研究背景和目的：视皮层是视觉的最高级中枢，视觉信息经由视觉通路最终传导到视皮层，再经皮层的分析与综合产生视觉。
