Effect of the D1 receptor antagonist SCH23390 on GABAA IPSCs evoked by minimal stimulation.A, Superimposed IPSCs in control (trace 1) and after application of SCH23390 (1 μm;SCH, 15 min; trace 2). The D1antagonist strongly reduced the amplitude of the GABAAIPSCs. Each trace represents the average of 10–15 traces.B, Time course of the change in the amplitude of IPSCs on application of the D1 antagonist SCH23390 and after coapplication of SCH23390 with the D1 agonist SKF38393 (3 μm; SCH+SKF). The D1antagonist SCH23390 strongly reduced the IPSC amplitudes and completely blocked the facilitating effects of the D1 agonist SKF38393. Each point represents the amplitude of an IPSC evoked by minimal stimulation at a repetition rate of 0.1 Hz.
