[Bioelectrical activity of limb muscles during shivering while stimulating the vestibular apparatus].
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.
