Electrophysiology of Intestinal Smooth Muscle

The electrophysiology of smooth muscle, despite the continuous development of new techniques, is still one of the most confusing and controversial fields of digestive physiology. The marked differences in smooth muscle properties in different segments of the gastrointestinal tract, in the various layers, and in different species have greatly contributed to this confusion. Controversy has also arisen concerning the extrapolation of results obtained from in vitro experiments to those obtained in vivo.
