Anticholinergic behavioral effect of phencyclidine
Abstract
Phencyclidine (PCP) impaired spatial alternation performance in rats. This effects was mimicked by antimuscarinic anticholinergics (scopolamine, atropine) and PCP derivatives (ketamine, cyclohexamine) but not by a variety of other agents. Muscarinic cholinergic agonists antagonized PCP. Impairment of spatial alteration performance by PCP appears to be mediated, at least in part, by and anticholinergic action; this is the first instance of a behavioral effect of PCP that can be largely attributed to a specific mechanism.
