摘要：

The present study examined effect of administration of a selective D1 dopamine receptor agonist. SKF38393 on extracellular concentrations of glutamate (Glu) and gamma-aminobutyric acid (GABA) in mPFC, by using in vivo microdialysis. Perfusion with SKF38393 via a dialysis probe reduced concentrations of both Glu and GABA dose-relatedly, and these effects were prevented by co-perfusion with a D1 dopamine receptor antagonist, SCH23390 (40 mu M) These results suggested that the dopaminergic hyperactivity may lead to the hypofunction of glutamatergic and GABAergic systems in mPFC via D1 dopamine receptor stimulation.
