The authors have previously shown that high alcohol preference rats (HAP) have a significantly higher sensitivity than low alcohol preference rats (LAP) for methamphetamine (MAP). In this study, changes in dopamine and serotonin release induced by MAP (1 mg/kg, intraperitoneally) after pre-treatment with D1 and D2 receptor antagonists were examined in the striatum of rats with different alcohol preferences to elucidate differences in receptor levels between the two rat strains. D1 receptor antagonist SCH23390 or D2 receptor antagonist haloperidol were administrated intracerebroventricularly 10 min before MAP stimulation.
