Effect of DA receptor blockade on modafinil-induced locomotion. Dbh +/− and Dbh −/− mice were placed in locomotor activity chambers and injected with vehicle or flupenthixol (0.25 mg/kg, i.p.) 3.5 hours later. Thirty minutes following the pretreatment, mice were injected with modafinil (50 mg/kg, i.p.), and ambulations (consecutive beam breaks) were recorded for an additional 2 hours. Shown are the total ambulations for the two hours after modafinil administration. * P < 0.05 compared to vehicle control for that genotype.
