Verapamil occludes the current reduced by dopamine. A: current traces recorded in sequence during voltage clamp step to −10 mV in control, verapamil (50 μM; VPM), and verapamil + dopamine (10 μM; VPM+DA). B: steady-state current-voltage relations show reduction of current by verapamil and subsequent modest further reduction by dopamine. C: % of peak control current that was blocked by verapamil (same data as in Fig. 2J) compared with block of current by verapamil and dopamine together. *P < 0.05.
