Figure 5.

Study 3, the effects of GES current (0, 1, or 2 mA; 10 min; site 1; Fig. 1) on emesis and esophageal contractions alone or combined with gastric distension (10 min of 3 or 4 ml of balloon inflation; n=5/group). The left column shows the 3 and 4 ml groups prior to distension. (A) Number of emetic episodes. (B) Cumulative proportion of animals showing the latency to the first emetic episode. (C) Number of esophageal contractions. Red dots = scatter plot of raw data; bars = mean ± SEM.
