Abstract

Neurons within the ventral portion of the oculomotor nucleus respond to stretch of extraocular muscles. Response latencies range from 30 to 170 ms. Antidromically identified extraocular motoneurons with this input have slowly conducting axons in the range of 30 to 50 m/s. Only responses to stretch of muscles other than those innervated by these motoneurons were recorded. Responses to stretch of several muscles from both eyes are common.

摘要

动眼神经核腹侧部的神经元对眼外肌的牵张作出反应。反应潜伏期为30至170毫秒。具有这种输入的经逆向鉴定的眼外运动神经元，其轴突传导速度较慢，在30至50米/秒范围内。仅记录了对这些运动神经元所支配肌肉以外的肌肉牵张的反应。对双眼多块肌肉牵张的反应很常见。
