title: [Neuronal activity of the submucous plexus of the pyloric and ileocecal sphincters].
abstract: In plexus of isolated segments of pyloric and ileo-caecal sphincters of the cat, three types of spontaneously active cells were revealed: 1) with single, 2) with fast, and 3) with slow burst type of discharges, as well as a group of silent neurons only responding to mechanical stimulation with electrode or application of acetylcholine. The data obtained indicated the qualitative unity of neuronal organization of submucous plexus along the alimentary canal, the neurons of the sphincters' plexus included. However, an increasing number of the silent cells and neurons with the single burst activity were revealed in the vicinity of mesenteric border and in the central belt of the segment which, probably, reflected the functional specifics of sphincters.
