On the Action Potential of the Dog's Stomach

The fact that the distinct action potential excluding all the possible artifacts could be recorded from dog's stomach by bipolar lead, has been established. 1) It is reasonable to accept that the action potential of the stomach consists of two componenrs. The first is the slow basic electrical rhythm or slow potential fluctuation, and the second is the bursts of fast potentials superimposed on the former. 2) There is no relationship between the electrical activities of the stomach and that of the duodenum. 3) The effects of autonomic stimulating agents such as adrenaline, besacholine, acetylcholine, atropine on the electrical activities of the stomach were observed. 4) The changes in the electrical activity resulted by the repoated stimulation of the vagus nerve or by the vagotomy were discussed.
