Phencyclidine-like behavioral effects in pigeons induced by systemic administration of the excitatory amino acid antagonist, 2-amino-5-phosphonovalerate

A selective N-methyl-D-aspartate antagonist, DL-2-amino-5-phosphonovalerate, was found to produce PCP-like catalepsy, discriminative stimulus effects, and stereotyped operant responding in pigeons when administered intramuscularly. These results support the hypothesis that the behavioral effects of PCP-like drugs result at least in part from reduced neurotransmission at excitatory amino acid synapses utilizing N-methyl-D-aspartate preferring receptors.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/26045/1/0000118.pd
