Measure the time-varying electrical activity of the gastrointestinal system of human and animal subjects, invasively or noninvasively. Gastrointestinal motility is directed by chemical, neural, and myogenic control systems. The myogenic control system is manifested by slow wave cyclic depolarizations of smooth muscle cells called the electrical control activity (ECA). This myogenic system and the resulting electrical response activity (ERA) influence the contraction patterns in the stomach, small intestine, and colon. The myogenic system affects the frequency, coordination, direction, and velocity of the contractions. The combined ECA and ERA signals constitute the electrogastrogram (EGG) recorded by the EGG100C.
