The genetically-inbred Balb/c mouse strain shows heightened sensitivity to the ability of MK-801 (dizocilpine), a noncompetitive NMDA receptor antagonist, to raise the threshold voltage necessary to precipitate tonic hindlimb extension and elicit irregular episodes of intense jumping behavior (referred to as "popping"), relative to other inbred mouse strains and the outbred NIH Swiss mouse....

The expression of the alpha7-nicotinic acetylcholine receptor is diminished in selected brain areas of patients with schizophrenia. This diminished expression may account for the pathophysiological deficits of sensory inhibition and smooth pursuit eye movement performance in these patients. Furthermore, the deficits in sensory inhibition and smooth pursuit eye movement performance in...

The ability of phencyclidine (PCP), a noncompetitive antagonist of NMDA receptor-mediated neurotransmission, to precipitate a schizophreniform psychosis in susceptible individuals is consistent with the hypothesized pathologic occurrence of NMDA receptor hypofunction in this disorder. Because the psychosis caused by PCP resembles schizophrenia in all of the relevant domains of psychopathology,...

The phencyclidine (PCP) model of schizophrenia suggests that N-methyl-D-aspartate (NMDA) receptor hypofunction and its consequences may play an important role in the pathophysiology of this psychiatric disorder. Moreover, the schizophreniform psychosis caused by PCP resembles schizophrenia in all of the relevant domains of psychopathology, especially negative symptoms and cognitive dysfunction....

MK-801, a high-affinity phencyclidine (PCP) analogue, is a noncompetitive antagonist of the N-methyl-D-aspartate (NMDA) subclass of glutamate receptor that elicits hyperactivity, stereotypic behaviors, and "popping," an explosive episodic jumping behavior, in mice. The schizophreniform psychosis precipitated by PCP in humans has stimulated interest in studying MK-801-elicited mouse behaviors...
