Electrophysiological study on nervous pathway from splanchnic nerve to vagus nerve in rat.

Action potentials evoked by the stimulation of the hepatic branch of the splanchnic nerve were recorded from the peripheral cut end of the dorsal celiac branch of the vagus nerve in the rat. Action potentials were clearly demonstrated after averaging over 100 times by a computer. The observations indicate the existence of a nervous pathway from the hepatic branch of the splanchnic nerve to the dorsal celiac branch of the vagus nerve in the rat.
