应用放射自显影技术测定了恒河猴上级丘和枕的投射。枕叶皮质投射至枕叶和枕外侧（PL），枕叶皮质投射至枕下（PI）。PI有持续的，地形投影层IV，III和I的区域18和19（和VI和I的17），同意中央代表的视觉半野，并建议有一个以上的nemifield代表在纹前皮质。与PI相邻的PL也投射到相同的皮质区域和层，而PL延伸到枕尾极的部分投射到区域20和21的IV、III和I层。枕叶皮质与皮质-丘脑皮质连接，并通过SC-PI和背外侧膝状体核（DLG）直接接受丘系输入，而颞下区20和21只接受皮质-丘脑皮质连接。显然Stoffel的分层原理成立，1枕亚部投射到几个皮质区，相邻的枕亚部有重叠的投射到这些皮质区及其层，枕也投射到与DLG相同的皮质区，但投射到不同的层。这些连接类似于低等哺乳动物，但不像松鼠猴和松鼠猴。
An autoradiographic technique was used to determine superior colliculus (SC) and pulvinar projections in the rhesus monkey. SC projected bilaterally to the inferior pulvinar (PI) while occipital cortex projected to PI and the lateral pulvinar (PL). PI had sustaining, topographical projections to layers IV, III and I of areas 18 and 19 (and VI and I of 17) which agreed with the central representation of the visual hemifield and suggests that there is more than 1 nemifield representation in prestriate cortex. PL adjacent to PI also projected to the same cortical areas and layers, while the portion of PL extending into the caudal pole of the pulvinar projected to layers IV, III and I of areas 20 and 21. Occipital cortices were associated by cortico-thalamocortical connections and also received direct lemniscal input via SC-PI and the dorsal lateral geniculate nucleus (DLG), while inferotemporal areas 20 and 21 received only cortico-thalamocortical connections. Apparently Stoffel''s principle of lamellation holds, 1 pulvinar subdivision projects to several cortical areas, adjacent pulvinar subdivisions have overlapping projections to these cortical areas and their layers and the pulvinar also projects to the same cortical area as DLG but to different layers. These connections were similar to those in lower mammals but not to those in the squirrel monkey and bushbaby.
