pretreatment of pigeons with alpha-methyltyrosine ( alpha-mt ) reduced d-amphetamine-induced pecking , while the combined treatment of pigeons with alpha-mt and l-dihydroxyphenylalanine ( l-dopa , 100 mg/kg ) partially restored the pecking response . d-amphetamine-induced pecking was not reduced by a dopamine-beta-hydroxylase inhibitor , 1-phenyl-3- ( 2-thiazolyl ) -2-thiourea ( u-14,624 ) .
