Abstract
An analysis of results of extracellular recording of neuronal activity of the cat heart ganglia showed that neurons of the intracardiac ganglia, in contrast to the neurons of other visceral ganglia, were characterized by the absence of spontaneous electrical activity. Variations in the duration and frequency of mechanically induced spike discharge are indicative of a different degree of neuronal membrane depolarization and its stability in time after mechanical action of the tip of the recording microelectrode on the cell. The evoked electrical activity was not dependent on the rhythm of local contractions of the myocardium. Some evidence of interneuronal interaction at the ganglion level under the conditions of complete isolation of the right auricle has been presented.
