[Smooth muscle biopotentials and the contractile activity of the stomach]

In chronic experiments on dogs, every peristaltic wave of the stomach was syndhronous with a burst of spike potentials on its secondary electric wave. Its primary electric waves are a xyndhronizer of tis peristalsis. In normal physiological conditions, the amplitude of the stomach primary electric waves was shown to be relatively stable, while regarding its functional condition the amplitude of its peristaltic waves may change to a great extent: from 0 to 200 g.
