Behavioral assessment of atypical antipsychotics in rats: studies of the effects of olanzapine (Zyprexa).

abstract：:Aniamls were administered increasing doses of morphine for 16 days. During withdrawal they were challenged with an apomorphine ester or lergotrile. These dopamine agonists produced quantitatively different effects on behaviour. The results suggest that chronic morphine administration leads to dopamine supersensitivity...
