title: [Autonomic nerve firing and small intestinal motoricity following introduction of a sucrose solution into its lumen].
abstract: Changes in potentials and motility of the longitudinal and circular muscles of the small intestine, as well as the impulsation of afferent fibers of the mesenteric, splanchnic, and vagus nerves and the impulsation of sympathetic efferent fibers at the pre- and post-ganglionic levels during excitation of the mucosa by 1 M sucrose solution, were studied in acute experiments on cats. Intraluminal administration of sucrose increased the motility of both muscle layers as well as spike potential and firing rate of mesenteric afferents, decreased the firing rate of the left vagus afferents, and evoked a biphasic change of the firing rate of the left splanchnic afferents. The firing rate of sympathetic efferents increased.
