the parkinson-syndrome induced by drugs which depress dopaminergic function either by reducing the output of dopamine , such as reserpine , or by antagonizing its action on da receptors , as for instance haloperidol or chlorpromazine , can be attributed to the augmented release of ach from caudate cholinergic nerve terminals and a consequent increase of cholinergic outflow from caudate nucleus .
