Abstract

The cerebellorubral projections have been studied in the rat using the retrograde transport of horseradish peroxidase-wheat germ agglutinin conjugate. The lateral cerebellar nucleus projects to the parvocellular red nucleus (RN), the anterior (NIA) and posterior (NIP) interposed nuclei project to the magnocellular RN. Whereas the projections from the NIP are limited to the medial aspect of the RN, those from the NIA extend throughout the magnocellular RN. NIA-RN projections are topographically arranged: the medial NIA projects ventrally, the lateral NIA projects dorsally. Functionally, this differential distribution seems to fit the hindlimb-forelimb areas of origin of the rubrospinal tract.

摘要

利用辣根过氧化物酶-小麦胚凝集素结合物的逆行运输，在大鼠中对小脑红核投射进行了研究。小脑外侧核投射至小细胞红核（RN），前间位核（NIA）和后间位核（NIP）投射至大细胞RN。虽然NIP的投射仅限于RN的内侧部分，但NIA的投射则贯穿整个大细胞RN。NIA-RN投射呈拓扑排列：内侧NIA向腹侧投射，外侧NIA向背侧投射。在功能上，这种差异分布似乎与红核脊髓束起源的后肢-前肢区域相匹配。
