A) In the presence of 1 μM of the CRF-R1 antagonist NBI27914 application of 3 μM isoproterenol does not alter sEPSC frequency
B) Application of 1 μM DA has no effect on evoked EPSCs. Inset, representative traces before (black) and after (red) DA application, calibration: 100 pA, 1 ms.
C) Bath application of 1 μM DA increases sEPSC frequency in the presence of 3 μM isoproterenol.
D) Application of 1 μM DA increases sEPSC frequency but does not occlude the increase in sEPSC frequency produced by application of 3 μM isoproterenol.
