Fig. 1. Climbing behaviors were measured after injection of apomorphine to each subject (2 mg/kg, s.c.). The pre-treatments were quetiapine (A (5 mg/kg), B (7 mg/kg) or C (10 mg/kg), i.p.), administered before the apomorphine treatment (after apomorphine treatment: control’, A’ (5 mg/kg), B’ (7 mg/kg), C’ (10 mg/kg), i.p.). Data are expressed as mean ± S.E. (n=15).
