猕猴上颞沟 (STS) 上岸的皮质，称为上颞多感觉 (STP) 区域，主要对应于结构区域 TPO，并且与相邻视觉区域有连接性不同。为了研究 STP 区域是否包含单独的细分，将小清蛋白和神经丝蛋白的免疫染色（使用 SMI-32 抗体）与 STS 中的皮质终止模式进行比较。化学结构结果为尾端到头端的三个细分提供了证据：TPOc、TPOi 和 TPOr。 TPOc 区域的特征是分别在皮质层 IV/III 和 III 中小白蛋白和 SMI-32 的斑片染色。 TPOi 区域具有更均匀的化学结构染色，而 TPOr 区域比 TPOi 具有更厚的 TV 层。连接结果显示，额叶眼野（区域 8）和背侧区域 46 位置的前额皮质以柱状图案投射到 TPOc 区域的所有皮质层、TPOi 的第四层，并以柱状方式投射到第四层到 TPOr 的密度适度增加。在 TPOc 中，额叶连接列显示出与 SMI-32 染色相似的周期性。尾部顶下小叶（区域 7a）和颞上回投射到 TPO 区域的每个细分，显示任一全层免疫染色，允许识别 STS 的尾部视觉区域，包括 MT、MST、FST 和 V4t。这些区域接收来自前额皮质和 7a 区域的第一层和第六层投射。 (C) 1995 Wiley-Liss, Inc.
Cortex of the upper bank of the superior temporal sulcus (STS) in macaque monkeys, termed the superior temporal polysensory (STP) region, corresponds largely to architectonic area TPO and is connectionally distinct from adjacent visual areas. To investigate whether or not the STP region contains separate subdivisions, immunostaining for parvalbumin and neurofilament protein (using the SMI-32 antibody) was compared with patterns of corticocortical terminations in the STS. Chemoarchitectonic results provided evidence for three caudal-to-rostral subdivisions: TPOc, TPOi, and TPOr. Area TPOc was characterized by patchy staining for parvalbumin and SMI-32 in cortical layers IV/III and III, respectively. Area TPOi had more uniform chemoarchitectonic staining, whereas area TPOr had a thicker layer TV than TPOi. The connectional results showed prefrontal cortex in the location of the frontal eye fields (area 8) and dorsal area 46 projected in a columnar pattern to all cortical layers of area TPOc, to layer IV of TPOi, and in a columnar fashion, with a moderate increase in density in layer IV, to TPOr. In TPOc, columns of frontal connections showed a periodicity similar to that of the SMI-32 staining. The caudal inferior parietal lobule (area 7a) and superior temporal gyrus projected to each subdivision of area TPO, displaying either panlaminar immunostaining allowed identification of caudal visual areas of the STS, including MT, MST, FST, and V4t. These areas received first-and sixth-layer projections from prefrontal cortex and area 7a. (C) 1995 Wiley-Liss, Inc.
