[Influence of the vagus nerve on the electromyographic activity of the antropyloric region in the rabbit].
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.
