Selected areas of sensorimotor cortex were stimulated with short trains adequate to evoke focal movements. Neurons belonging to the vestibular nuclear complex, including the lateral vestibular nucleus (LVN), were mainly affected by the stimulation of wrist-elbow, shoulder and cortical areas. The units responded to cortical stimulation either with a constant latency lower than 10 msec (short-latency units), or with variable latencies higher than 10 msec (long-latency units). Particular attention was paid to the first group of responses showing the involvement of direct and/or oligosynaptic facilitatory inputs from the cortical cells. Moreover, many of these responsive vestibular nuclear neurons were identified as projecting to the spinal cord.
用足以诱发局部运动的短串刺激来刺激感觉运动皮层的选定区域。属于前庭神经核复合体的神经元,包括外侧前庭核(LVN),主要受到手腕-肘部、肩部和皮层区域刺激的影响。这些神经元对皮层刺激的反应,要么是潜伏期恒定且低于10毫秒(短潜伏期单位),要么是潜伏期可变且高于10毫秒(长潜伏期单位)。特别关注的是第一组反应,其显示出皮层细胞的直接和/或少突触易化性输入的参与。此外,许多这些有反应的前庭神经核神经元被确定为投射到脊髓。
