title: [Changes in the activity of sympathetic neurons after stimulation of the afferent fibers of the stomach].
abstract: In acute experiments on anesthetized cats, the central stumps of nerve branches innervating different parts of the stomach were electrically stimulated. Impulses from sympathetic efferents of the left major splanchnic nerve and the smooth muscle potentials from the gastric pylorus were recorded. The prevalence of sympathoinhibitory effects was shown during stimulation of the gastric branch of the dorsal trunk and pyloric branch of the ventral trunk of vagus subphrenic branches. Weak stimulatory effects were observed during stimulation of the same nerves after cervical vagotomy. The sympatho-inhibitory effect of stimulation of the vagus gastric branch persisted after transection of splanchnic nerves. In most experiments, changes in smooth muscle potentials corresponded to the changes in sympathetic neuron activity.
