Figure 9. Chronic, but not acute D1DR stimulation decreases NMDAR-mediated currents.
A) and B) Time-course of whole-cell responses to NMDA (100 µM) before and after pre-treatment with SKF38393 in saline controls and cocaine-experienced animals. C) Summary histograms of whole-cell NMDA responses expressed as current density (t(32)=2.1; *, p<0.05 vs. non-treated saline; n=17–25 cells). D) A summary of eEPSCs (Evoked) and whole-cell NMDAR responses during acute application of SKF38393. In the majority of cells, NMDAR-mediated currents are potentiated during SKF38393 application.
