Study 2, the effects of GES pulse length (0, 0.3, 1, 5, and 10 ms; 10 min; site 1, Fig. 1) on emesis and esophageal contractions alone or combined with gastric distension (10 min of 4 ml of balloon inflation; n=4/group). (A) Number of emetic episodes. (B) Cumulative proportion of animals showing the latency to the first emetic episode for different pulse lengths. (C) Number of esophageal contractions. Red dots = scatter plot of raw data; bars = mean ± SEM.
