title: Increased effect of apomorphine on homovanillic acid in rats terminated from chronic haloperidol.
abstract: Rats who were administered apomorphine seven days after termination of chronic treatment with haloperidol had significantly (59%) lower level of brain HVA than saline control rats. This finding is consistent with the behavioral evidence suggesting supersensitivity of post-synaptic dopamine receptors after termination of chronic haloperidol.
