Patterns of connections with other visual structures and architectonic characteristics were used to subdivide the inferior pulvinar complex of owl monkeys into three distinct nuclei termed the central inferior pulvinar, IPc, the medial inferior pulvinar, IPm, and the posterior inferior pulvinar, IPp. IPc occupies about 70%; IPm about 20%, and IPp about 10% of the inferior pulvinar complex. Encapsulating fiber bands distinguish the boundaries of the three nuclei. IPm is also identified by a much greater packing density of neurons than IPc and IPp. Both IPp and IPc receive input from the superior colliculus, but the terminations in IPp are denser. Visual cortical Areas 17, 18, MT, DM, M and PP (Allman and Kaas, '76) project to IPc and IPm in patterns that indicate that central vision is represented dorsorostrally and peripheral vision ventrocaudally in both nuclei. Terminations in IPm from Area MT are particularly dense. None of these visual areas projects to IPp. Rather, input to IPp appears to originate in cortex rostral to Area MT in the temporal lobe.
通过与其他视觉结构的连接模式和构筑特征，夜猴的下枕叶复合体被细分为三个不同的核团，分别称为中央下枕叶（IPc）、内侧下枕叶（IPm）和后下枕叶（IPp）。IPc约占下枕叶复合体的70%；IPm约占20%，IPp约占10%。包绕的纤维带区分了这三个核团的边界。与IPc和IPp相比，IPm的神经元堆积密度也明显更高。IPp和IPc均接受来自上丘的输入，但IPp中的终末更密集。视觉皮层17区、18区、MT区、DM区、M区和PP区（奥尔曼和卡斯，1976年）投射到IPc和IPm，其模式表明，在这两个核团中，中央视觉在背侧吻部代表，周边视觉在腹侧尾部代表。来自MT区的纤维在IPm中的终末特别密集。这些视觉区域均不投射到IPp。相反，IPp的输入似乎起源于颞叶中MT区前方的皮层。
