The purpose of this experiment is to confirm the effects of the descending pathway from the lateral vestibular nucleus (LVN) on rhythmic discharges induced by stimulation of the mesencephalic locomotor region (MLR) in the decerebrated cat. The experiments were performed on 18 adult cats (2.5-4.0 kg) of either sex. The rhythmic discharges produced by the MLR stimulation were recorded from hindlimb extensor muscle (LGS: lateral gastrocnemius and soleus) and flexor muscle (PBST: posterior biceps and semitendinosus) nerves. The LVN stimulation influenced the amplitude and interval of the rhythmic discharges in both extensor and flexor muscle nerves.
本实验的目的是证实去大脑猫中，外侧前庭核（LVN）下行通路对刺激中脑运动区（MLR）所诱发的节律性放电的影响。实验选用了18只成年猫（体重2.5 - 4.0千克），雌雄不限。通过记录后肢伸肌（LGS：外侧腓肠肌和比目鱼肌）和屈肌（PBST：股二头肌和半腱肌）神经的放电情况，来观察MLR刺激所产生的节律性放电。LVN刺激影响了伸肌和屈肌神经节律性放电的幅度和间隔。
