[Multichannel recording of gastric electric activity from the surface of the human body].

Technique of synchronous multichannel stomach biopotential recording from the anterior abdominal wall surface was elaborated. Multichannel electrogastrography permitted to record selective electric oscillation of various portions of the stomach from the surface of the anterior abdominal wall. Space-time and correlation tests of the electric activity of different portions of the stomach were carried out in the course of digestion.
