Corticothalamic connections were shown between the second somatosensory area in primates and the ventroposterior nuclei of the thalamus. These projections were topographically arranged with those from the hindlimb portions of SII traced to the most lateral and posterior parts of the ventroposterior lateral nucleus (VPLc) and those from the forelimb located medially within VPLc. The densest labeling was found ventrally in VPLc and dorsally within ventroposterior inferior n. (VPI) only after injections of the forelimb. A more scattered, dorsal distribution of labeling was seen in the rest of VPLc from injections involving more proximal parts of the body representation in SII.
在灵长类动物的第二躯体感觉区与丘脑腹后核之间显示出皮质丘脑连接。这些投射在拓扑学上有一定的排列，来自第二躯体感觉区后肢部分的投射追踪到腹后外侧核（VPLc）最外侧和后部，而来自前肢的投射位于VPLc内侧。仅在前肢注射后，在VPLc腹侧和腹后下核（VPI）背侧发现了最密集的标记。在涉及第二躯体感觉区中身体代表更靠近近端部分的注射后，在VPLc其余部分可见更分散的背侧标记分布。
