The effect of DFP, a long-acting inhibitor of acetylcholinsterase, on apomorphine-induced climbing behavior, was tested in mice. Twelve hours following the intraperitoneal administration of a single dose of DFP, animals demonstrated a significant increase in apomorphine-induced climbing behavior. This effect was not observed twenty-four hours following DFP pretreatment. These results suggest that acute administration of a cholinomimetic agent, may produce behavioral supersensitivity to dopamine agonists.
