Effects of CB1, LVGCC, and NMDAR antagonists on reconsolidation and extinction. A–C, Experimental design used with data presented below. A, Effects of ANI, SR141716A, nimodipine, and CPP on memory consolidation (n = 10 for all groups). B, Effects of ANI, SR141716A, nimodipine, and CPP on memory reconsolidation (n = 10 for all groups). C, Effects of ANI, SR141716A, nimodipine, and CPP on memory extinction. Freezing responses during reexposure are shown only for the highest dose of nimodipine (32 mg/kg), SR141716A (10 mg/kg), and CPP (20 mg/kg). Subsequent test data are shown in the right panel (n = 12 for all groups). C, Control; A, anisomycin; Nimo, nimodipine; SR, SR141716A.
