Abstract
The effects of caloric and electric stimulation of the vestibular receptors on the EMG activity of limb muscles in anesthetized cats during cold-induced shivering involved flexor muscles alone. Both types of stimulation suppressed bioelectrical activity, more effectivey in the ipsilateral muscles. The suppression of shivering activity seems to be due to the increased inhibitory effect of descending labyrinth pathways on the function of flexor motoneurons.
摘要
在冷诱导颤抖期间，对麻醉猫的前庭感受器进行热量和电刺激，其对肢体肌肉肌电图活动的影响仅涉及屈肌。两种刺激均抑制生物电活动，对同侧肌肉的抑制更有效。颤抖活动的抑制似乎是由于迷路下行通路对屈肌运动神经元功能的抑制作用增强所致。
