Modifications of electrical activity of the rabbit duodenum longitudinal muscle after contractions of the circular muscle
By recording, with extracellular electrodes, the electrical activity of both muscle layers of rabbit duodenum in vitro, it has been shown that spike discharge of longitudinal fibers could be inhibited by a previous discharge of circular fibers. The sensitivity of this mechanism to drugs that disorganize the function of intramural plexuses suggests that it is nervous in origin.
