Abstract
The elctrical activity of the stomach of the dog was recorded with suction electrodes in monopolar lead in vivo and effects of vagus and splanchnic nerves stimulation on the elctrical activity in the stomach were studied. The electrical activity consisted of a rhythmic train of triphasic spikes, each being followed by a slow negative potential. Upon repetitive stimulation of the vagus nerve the slow potential increased its amplitude and intervals between the spikes prolonged. Splanchnic nerve stimulations caused effects on the electrical activity in the stomach in different animals as follows; i) complete disappearance of the electrical activity during stimulation and several second after release of stimulation, ii) irregular appearance of the elctrical activity associated with decreases in an amplitude of the slow potential, iii) burst discharges of the spikes without having the slow potentials at the onset of stimulation, and thereafter no electrical activity during stimulation.
