In area 18 of the primate visual cortex, staining for the mitochondrial enzyme cytochrome oxidase reveals 3 types of stripelike subdivisions running perpendicular to the 17/18 border: thick, thin, and pale stripes. In a previous paper (Livingstone and Hubel, 1984), we described the anatomical connections with area 17 of 2 of these 3 subdivisions, but we did not have any conclusive information on the third subdivision, the thick stripes. Here we report that, in the squirrel monkey, the main input to the thick stripes from area 17 arises from layer 4B. Layer 4B receives its input from the magnocellular division of the lateral geniculate body by way of layer 4C alpha; the thick stripes therefore probably belong to the magnocellular subdivision of the visual pathway.
在灵长类动物视觉皮层的18区，线粒体酶细胞色素氧化酶染色显示有3种与17/18边界垂直的条纹状细分区域：粗条纹、细条纹和淡条纹。在之前的一篇论文（利文斯通和休伯尔，1984年）中，我们描述了这3个细分区域中2个与17区的解剖学连接，但对于第三个细分区域——粗条纹，我们没有任何确凿的信息。在此我们报告，在松鼠猴中，来自17区对粗条纹的主要输入来自第4B层。第4B层通过第4Cα层从外侧膝状体的大细胞部分接收输入；因此粗条纹可能属于视觉通路的大细胞细分区域。
