MULTIPLE INNERVATION OF AMPHIBIAN SYMPATHETIC GANGLION CELLS

抄録

Intracellular recording was made from B neurons of bullfrog paravertebral ganglia in situ. Analysis of the tonically occurring fast e. p. s, p. s revealed that approximately 50 % of B neurons receive a multineuronal innervation and that the rest receive a unineuronal innervation which had been thought to be the characteristic innervation pattern in the amphibian sympathetic ganglia. Similar results were also obtained from the analysis of the fast e. p. s. p. s evoked by stimulation of the spinal nerves containing the spinal B fiber outflows.
