After 100 years of progress in understanding the organization of cerebral cortex, three issues have persisted over the last 35 years, which are revisited in this paper. First, is V3 an established or questionable area of visual cortex? Second, does taste cortex include part of area 3b (S1 proper) and other somatosensory areas? Third, is primary auditory cortex, A1, of primates the homologue of A1 in cats? The existence of such questions about even the early stages of cortical processing reflects the difficulties in mapping cerebral cortex, and reminds us that the era of basic discovery is far from over.
在对大脑皮层组织的理解取得百年进展之后，过去35年里一直存在三个问题，本文将重新探讨这些问题。第一，V3区是视觉皮层中一个已确定的区域还是存在疑问的区域？第二，味觉皮层是否包括3b区（狭义的初级体感皮层S1）的一部分以及其他体感区域？第三，灵长类动物的初级听觉皮层A1是否与猫的A1区同源？即使是关于皮层处理早期阶段的这些问题的存在，也反映了绘制大脑皮层图谱的困难，并提醒我们基础发现的时代远未结束。
