Abstract

The lateral reticular nucleus of the medulla oblongata (LRN) in the rat was observed after injecting horseradish peroxidase (HRP) bilaterally into the anterior lobe of the cerebellum; the inferior cerebellar peduncle had been cut unilaterally prior to the HRP injections. HRP-labeled neurons were seen bilaterally in the LRN; 89% in the contralateral, and 11% in the side ipsilateral to the pedunculotomy. The labeled neurons in the LRN ipsilateral to the pedunculotomy were assumed to send their axons to the anterior lobe of the cerebellum via the controlateral inferior cerebellar peduncle. Of these neurons, 60, 11 and 29% were distributed in the magnocellular, subtrigeminal and parvicellular divisions of the LRN, respectively.

摘要

在将辣根过氧化物酶（HRP）双侧注射到大鼠小脑前叶后，观察了延髓外侧网状核（LRN）；在注射HRP之前，已单侧切断小脑下脚。在LRN中双侧可见HRP标记的神经元；对侧占89%，在小脑下脚切断侧的同侧占11%。推测在小脑下脚切断侧同侧LRN中的标记神经元通过对侧小脑下脚将其轴突发送至小脑前叶。在这些神经元中，分别有60%、11%和29%分布在LRN的大细胞部、三叉下和小细胞部。
