Using bilateral infusions into the rat striatum, the effects of the competitive NMDA receptor antagonist 2-amino-5-phosphopentanoic acid (AP5) on behaviors induced by the dopamine (DA) D1 receptor agonist SKF 82526 (fenoldopam) or the D2 receptor agonist quinpirole were determined. These effects were tested in DA-replete (intact) rats and in rats that were(More)
Experiments measuring behavior and immediate-early gene expression in the basal ganglia can reveal interactions between dopamine (DA) and glutamate neurotransmission. Nigrostriatal DA projections influence two striatal efferent pathways that, in turn, directly and indirectly influence the activity of the substantia nigra pars reticulata (SNr). This report(More)
Repeated administration of methamphetamine (m-AMPH) produces a prolonged elevation of extracellular dopamine (DA) levels in rat striatum and subsequent damage to striatal DA terminals. In the present study, a unilateral striatal infusion of quinolinic acid (QA) (15 ug/0.5 microliter) 2 weeks before repeated m-AMPH treatment (four injections of 4 mg/kg,(More)
