将辣根过氧化物酶（HRP）注入猕猴[Macaca nemestrina，M. fascicularis]猴，标记细胞在新皮质中被限制在V层的所有领域，除了纹状视皮质。视皮层V层和VI层均可见皮质-顶盖细胞。两层的标记细胞属于不同的细胞群：第V层为普通锥体细胞，第VI层为Meynert孤细胞。这一发现可能为皮质-丘通路的生理学提供新的见解。灵长类动物的纹状区在皮质-顶盖层特异性方面与其他新皮质不同。
After injections of the enzyme horseradish peroxidase (HRP) into the superior colliculus of macaque [Macaca nemestrina, M. fascicularis] monkeys, labeled cells in the neocortex were restricted to layer V in all areas except striate visual cortex. In striate visual cortex, cortico-tectal cells were found both in layer V and in layer VI. The labeled cells in the 2 layers belonged to morphologically different populations: those of layer V were the common pyramidal cells and those of layer VI were identified as solitary cells of Meynert. This finding may provide new insights into the physiology of the cortico-collicular pathways. The striate area in primates differs, with respect to cortico-tectal laminar specificity, from other neocortex.
