Data are means ± SE; n, no. of rats. CPP, conditioned place preference; SH, saline hypoglycemia; RH, recurrent insulin-induced hypoglycemia; SERT, sertraline; SAL, saline; VEH, vehicle; HYPO, hypothalamic. On alternating days (days 2, 4, and 6 or days 3, 5, and 7), rats received approximately 3 g chocolate (Nestle Chocolate Drops) on the nonpreferred side (as determined from the pretest on day 1), and their intake was measured. There were no significant differences between groups.
