通过小量注射逆行传输的荧光染料来确定投射到猴子顶下小叶的两个亚区域——外侧顶内区 (LIP) 和 7a 区的枕神经元的分布。 LIP 和 7a 的丘脑输入大部分都来自内侧枕核内连续但不同的区域。投射到 LIP 的丘脑皮质细胞体排列成密集的水平方向簇，夹在投射到 7a 的两个相似的神经元簇之间。各个簇之间的重叠极小。 LIP 还从外侧枕核的背半部分接收到明显的输入，但 7a 中的示踪剂放置导致外侧枕核中仅偶尔出现标记的神经元。
The distribution of pulvinar neurons that project to the lateral intraparietal area (LIP) and area 7a, two subregions of the inferior parietal lobule in monkeys, was determined using small injections of retrogradely transported fluorescent dyes. Both LIP and 7a received the majority of their thalamic input from contiguous but distinct zones within the medial pulvinar nucleus. Thalamocortical cell bodies that projected to LIP were arranged in a dense, horizontally oriented cluster that was sandwiched between two similar clusters of neurons that projected to 7a. There was minimal overlap of the respective clusters. LIP also received an appreciable input from the dorsal half of the lateral pulvinar nucleus, but tracer placements in 7a resulted in only occasional labeled neurons in the lateral pulvinar.
