The electromyographic activity of the stomach antrum and pylorus was recorded in rabbits in acute experimental conditions. Stimulation of the distally cut end of a cervical vagus induced an increase of EMG activity. These results confirm the existence of motor efferent fibers in the vagus. Stimulation of the central end of the vagus inhibited the spontaneous or evoked EMG activity. It is likely that the efferent fibers stimulated by the afferent volley were preganglionic, synapsing with inhibitory myenteric neurons.
在急性实验条件下记录了家兔胃窦和幽门的肌电活动。刺激颈迷走神经的远侧切断端可使肌电活动增加。这些结果证实了迷走神经中运动传出纤维的存在。刺激迷走神经的中枢端可抑制自发或诱发的肌电活动。传入冲动所刺激的传出纤维可能是节前纤维，与抑制性肠肌神经元形成突触。
