We measured [125I] iomazenil binding, labeling the central-type benzodiazepine receptor in 37 discrete rat brain areas following single (7.5 mg/kg, i.p.) and repeated (7.5 mg/kg/day x 14 days, i.p.) treatment with phencyclidine (PCP), a non-competitive antagonist of the N-methyl-D-aspartate(NMDA)-type glutamate receptor, using in vitro quantitative autoradiographic receptor binding assay. Both...
