损毁家兔单、双侧室旁核，观察迷走神经对皮层诱发的下颌运动抑制性影响的变化，发现损毁单侧室旁核不影响刺激迷走神经中枢端对皮层诱发的下颌运动的抑制作用；损毁双侧室旁核，迷走神经对皮层诱发的下颌运动的抑制作用消失。
The single and bilateral paraventricular nucleus were injured in rabbits to observe the changes of inhibitory effects of vagus nerve on cortical-induced mandibular movement. It was found that the unilateral paraventricular nucleus ruptured did not affect the inhibition of cortical-induced mandibular motility in the central vagus nerve. Paraventricular nucleus, vagus nerve on the cortex-induced jaw motion disappeared.
