Abstract In the context of the in vivo neurochemical literature this article reviews some recent microdialysis studies in our laboratory of glutamate-dopamine interaction in the prefrontal cortex (PFC) and its possible role in modulating dopamine and acetylcholine release in the nucleus accumbens. A functional glutamate-dopamine interaction in PFC has been reported by microdialysis studies showing that both stimulation and blockade of prefrontal glutamate receptors produce changes of basal and/or stimulated release of dopamine in this area of the brain. These studies suggest that dopamine function in PFC is modulated locally by prefrontal glutamatergic inputs and that glutamate and dopamine can act simultaneously to regulate GABA release in PFC. In particular, dopamine can enhance the increases of extracellular GABA produced by the stimulation of prefrontal glutamate receptors. We report also that the stimulation of prefrontal D2 and mGluI receptors and their interaction changes the release of dopamine and acetylcholine in the nucleus accumbens.
