Taste preference effects of bilateral intra-IC injections and intra-NBM injections of muscimol and bicuculline. Consumption of saccharin as a novel tastant (A: saline, n = 11; muscimol, n = 10; bicuculline, n = 11) and (C: saline, n = 12; muscimol, n = 12; bicuculline, n = 12). Consumption of saccharin as a familiar tastant (memory retrieval) (B: saline, n = 12; muscimol, n = 12; bicuculline, n = 13) and (D: saline, n = 10; muscimol, n = 11; bicuculline, n = 11). Data are shown as the percentage saccharin consumption ± SEM, *p < 0.05, **p < 0.001 versus control. Arrows indicate injection day.
