Abstract

The characteristics of the response to an 8 degrees/sec2 acceleration of 41 neurons in the medial vestibular nucleus of the cat following vestibular nerve sectioning were compared with those of 73 control neurons at the same site. In 14 of the vestibular nerve-sectioned animals the same neuron was recorded before and after sectioning. No difference was found between the resting discharge rates, maximal response rates, and rates of adaptation of the two groups. Following contralateral vestibular nerve sectioning Type II neurons were still plentiful, suggesting many receive ipsilateral labyrinthine innervation.

摘要

将猫前庭神经切断后，内侧前庭核中41个神经元对8度/秒²加速度反应的特征与同一部位73个对照神经元的特征进行了比较。在14只接受前庭神经切断的动物中，在切断前后记录了同一个神经元。两组在静息放电率、最大反应率和适应率方面均未发现差异。对侧前庭神经切断后，II型神经元仍然大量存在，这表明许多神经元接受同侧迷路神经支配。
