[Spontaneous activity of myenteric plexus neurons in the intact rabbit small intestine].

In rabbits intact myenteric plexus segments of the intestine, two types of neurons in regard to their electric discharges, were found: 1) units with single spontaneous spikes at the mean firing rate 2.3/sec and with interspike intervals from 140 to 900 msec; 2) units firing bursts of 3--12 spikes with interspike intervals of about 30 msec.
