Effect of posttraining administration of WIN55,212-2 on 1-h retention of rats in the WITHOUT- and WITH-habituation conditions. Posttraining administration of WIN55,212-2 (WIN, 0.3 mg/kg, i.p.) impaired 1-h retention of object recognition memory of rats in the WITHOUT-habituation condition (a) but enhanced 1-h retention of rats in the WITH-habituation condition (b). *P<0.05 vs the corresponding vehicle control group. Data are expressed as mean±SEM (n=12 per group).
