Effects of clozapine (5, 10 mg/kg) on amphetamine-induced LI disruption in sham and OVX rats. Mean (±SEM) log times to complete licks 76–100 (after tone onset) of the pre-exposed (PE) and the non-pre-exposed (NPE) saline- or amphetamine (amph)-injected sham and OVX rats that received clozapine (5 or 10 mg/kg to half of the group), amphetamine+5 mg/kg clozapine, or amphetamine+10 mg/kg clozapine. Asterisks (**) indicate significant difference between the PE and NPE groups, namely, presence of LI (p<0.01).
