A somesthetic inhibitory projection onto rubrospinal cells in the cat is described. It is suggested that the pathway, which is not dependent upon an intact cerebellum or motor cortex, travels through the dorsal columns of the spinal cord. The second order neurons seem to impinge upon inhibitory interneurons situated within the red nucleus itself. The burst activity in such interneurons might account for the IPSPs seen in rubro-spinal cells. In agreement with the idea that the red nucleus may be part of a feed-back loop through the periphery, the pathway described here could be the link giving suppression of rubral activity during some phases of limb movement.
本文描述了猫中向红核脊髓细胞的一种躯体感觉抑制性投射。据推测，该通路不依赖于完整的小脑或运动皮层，而是通过脊髓背柱传导。二级神经元似乎作用于位于红核本身内的抑制性中间神经元。此类中间神经元的爆发性活动可能是红核脊髓细胞中所见抑制性突触后电位的原因。与红核可能是通过外周的反馈回路一部分的观点一致，此处描述的通路可能是在肢体运动的某些阶段抑制红核活动的连接环节。
