Using the HRP method we have identified eleven groups of spinocerebellar tract (SCT) neurons in the cat, and determined their projection areas in the anterior and the posterior lobes. Neuronal groups projecting to lobule VIII are located in the central cervical nucleus (CCN), Clarke's column and the medial part of lamina VII of L6 to the caudal segments while those projecting to the paramedian lobule are lamina V neurons of C8 to L4, marginal neurons of Clarke's column and spinal border cells. In the anterior lobe the CCN projects to lobules I to V, most abundantly to lobules I and II. The medial lamina VII group of L6 to the caudal segments projects mainly to lobules I and II. Spinal border cells project to lobules II to V, but predominantly to lobules III and IV. Clarke column neurons project to lobules I to V. The medial lamina VI group and the central lamina VII group of the cervical segments project to lobules III and IV. Marginal neurons of Clarke's column and lamina V neurons of the lower cervical to the lumbar segments project to lobules III to V. The present study suggests that the SCT neurons project to different sagittal zones of the cerebellar cortex, with various quantities in the rostrocaudal direction.
我们运用辣根过氧化物酶（HRP）法，在猫身上识别出了11组脊髓小脑束（SCT）神经元，并确定了它们在前叶和后叶的投射区域。投射至小叶VIII的神经元群位于颈中央核（CCN）、克拉克柱以及L6至尾段的VII层内侧部分，而投射至旁正中小叶的神经元群则是C8至L4的V层神经元、克拉克柱边缘神经元和脊髓边界细胞。在前叶，CCN投射至小叶I至V，其中投射至小叶I和II的最为丰富。L6至尾段的VII层内侧组主要投射至小叶I和II。脊髓边界细胞投射至小叶II至V，但主要投射至小叶III和IV。克拉克柱神经元投射至小叶I至V。颈段的VI层内侧组和VII层中央组投射至小叶III和IV。克拉克柱边缘神经元以及下颈段至腰段的V层神经元投射至小叶III至V。本研究表明，SCT神经元投射至小脑皮质的不同矢状区，在头尾方向上数量各异。
