The postsynaptic effects of dopamine in the neostriatum are mediated by five G-protein-coupled receptors. The extent to which these receptors are co-localized in neostriatal neurons has become controversial. This debate has far-reaching implications for treatment strategies in disorders of dopaminergic signaling, such as Parkinson's disease and schizophrenia. This review examines the molecular and cellular evidence for and against co-localization, including new information derived from single-cell mRNA amplification and patchclamping of isolated neurons. It is concluded that this evidence is largely consistent with co-localization of functionally significant receptors of the D1 and D2 families in the majority of neostriatal efferent neurons. This conclusion has important implications for parallel processing models of the neostriatum.
