N-methyl-D-aspartate receptors (NMDARs) are comprised of different subunits. NR2 subunits confer different pharmacological and biophysical properties to NMDARs. Although NR2B subunit expression is uniform throughout striatum, NR2A subunit expression is greater laterally. Pharmacologically isolated NMDAR-mediated excitatory postsynaptic currents(More)
The abuse of psychostimulants, such as methamphetamine (METH), can cause long-lasting deficits in the dopamine (DA) innervation of the striatum. Although the consequences of large DA depletions on basal ganglia function have been well characterized, less is known about the alterations associated with smaller depletions, such as those produced by high doses(More)
Methamphetamine (METH) causes partial depletion of central monoamine systems and cognitive dysfunction in rats and humans. We have previously shown and now further show that the positive correlation between expression of the immediate-early gene Arc (activity-regulated, cytoskeleton-associated) in the dorsomedial (DM) striatum and learning on a response(More)
