Original cells and muclei of the descending spinal tracts detectrd bu HRP injection in the C5-7 or L1-5 spinal cord were gigantocellular reticular, external cuneate, prepositus of XII,lateral reticular, vestibular, mesencephalic V and red nuclei in the pons examined. In the medulla and midbrain, Cells of deep gray of the superior colliculus were aiso marked. In the cortex pyramidal cells of V layr were marked, butcell population is diffuse.In the cerebellum showed clearly marking on the inferior olive, external cuneate, and vestibular nucler. But marked cells in the pons wew very limited.It is assumed that motor activity of the suncus is triggered by cerebral cortex, but it's continuance seemed to depend mainly on the extrapyramidal system.

在C5-7或L1-5脊髓注射HRP所见的脊髓下行束原始细胞和核有巨细胞网状核、外楔状核、XII前置核、外侧网状核、前庭核、中脑V核和红核。在延髓和中脑，上丘的深灰色细胞也被标记。皮质内V layR区锥体细胞明显，但细胞群弥漫，小脑下橄榄核、外楔状核、前庭核均有明显标记。但脑桥标记细胞的数量非常有限，一般认为大脑皮质触发的运动活动主要依赖于锥体外系。
