Conditioned taste aversion. A: saccharin (S) and water (W) intake in sham-operated rats after oral gavage with 1 ml sterile isotonic saline (n = 8), 1 ml of corn oil (n = 8), intraperitoneal injection of 76.2 mg/kg body wt LiCl (n = 6), and in gastric bypass rats after oral gavage with sterile isotonic saline (n = 8) and corn oil (n = 8). B: saccharin intake expressed as % total fluid intake in sham-operated rats after oral gavage with sterile isotonic saline (n = 8), corn oil (n = 8), intraperitoneal injection of 76.2 mg/kg body wt LiCl (n = 6), and in gastric bypass rats after oral gavage with sterile isotonic saline (n = 8) and corn oil (n = 8). Experiments were performed on postoperative day 100. Data are means ± SE (**P < 0.01, ***P < 0.001; saccharin vs. water).
