Figure 3.

Effects of post-training systemic injections of corticosterone (1.0 or 3.0 mg/kg, s.c.) on taste aversion when administered either after the consumption of saccharin or after the LiCl injection as assessed on a 96-h retention test trial. (A,B) Experimental design. (C,D) Corticosterone administration after the LiCl injection, but not after the saccharin consumption, enhanced taste aversion on a 96-h retention test. The aversion index (mean + SEM) is expressed as the percent saccharin consumption on the retention test as compared with that during acquisition. (*) P < 0.05 as compared with the vehicle (Veh) group (n = 12–14 rats per group).
