Research output: Contribution to journalArticlepeer-review


The purpose of this study was to reevaluate the distribution and the number of intracardiac
ganglion cells in the rat. Hearts were excised from adult male Wistar rats. The distribution
of the ganglia was mapped using thick, frozen sections of rat heart histochemically stained
for acetylcholinesterase. The ganglion cells were divided into several groups with the
largest group located dorsal to the inferior interatrial septum. The disector method was
used to estimate the number of neurons in seven micron thick paraffin sections. The number
of neurons in the rat heart was 3629±337 (mean ±S.E., n=3).
