Phencyclidine (PCP) is a hallucinogenic drug that can mimic several aspects of the schizophrenic symptomatology in healthy volunteers. In a series of studies PCP was administered to rats to determine whether it was possible to develop an animal model of the positive and negative symptoms of schizophrenia. The rats were tested in the social interaction test and it was found that PCP...
D-amphetamine (AMPH) and phencyclidine (PCP) can induce a model psychosis that mimic the positive symptoms of schizophrenia, but only PCP also mimics the negative symptoms. Recent studies in the rat social interaction test have shown that PCP, and not AMPH, induce social withdrawal following single and repeated injections, and this effect may, therefore, be used to model negative symptoms....
Phencyclidine (PCP) can induce a model psychosis in humans that mimics the positive and negative symptoms of schizophrenia. In the social interaction test PCP induces stereotyped behaviour and social isolation in rats, and these behaviours can be inhibited by antipsychotic drugs. In order to further evaluate the predictive validity of this model of schizophrenia the anxiolytic diazepam...
Phencyclidine (PCP) can induce a model psychosis in humans that resembles an acute schizophrenic psychosis. In animal models of schizophrenia, PCP induces locomotor hyperactivity, stereotyped behaviour and social isolation, and the purpose of the present study was to describe the ability of dopamine agonists and antagonists to mimic or interact with these PCP-induced behaviours in rats. The...
