Fig. 10. The post- retrograde giant contraction (RGC) activation of intestinal motor activation. This figure depicts the occurrence of the digestive tract correlates of vomiting, activated by chemical stimulation of the digestive tract, without activation of retching or vomitus expulsion. The lack of vomiting prevents respiratory artifact from fully exposing the post-RGC activation of intestinal motor activity. This figure also demonstrates the increased duration of the post-RGC activation of intestinal motility in more distal sections of the intestine, and the occurrence of these contraction in areas of the intestine caudad of the RGC (JeJ-IL [365] and [435]). JeJ-IL, jejunum-ileum. The numbers in parenthesis indicate the location of the strain gauge from the pylorus. Adapted from Lang et al.
