the relative contribution of catecholaminergic mechanisms in head-shaking ( h-s ) of infant rats was explored by comparing the h-s inducing effects of apomorphine and amphetamine in rats from 4-14 days old , and the blocking effect of neuroleptic drugs ( chlorpromazine and haloperidol ) and more specific alpha- and beta-adrenergic receptor antagonists ( phenoxybenzamine and propranolol ) , on amphetamine induced head-shaking .
