Releasable pools of DA are not depleted in the presence of sulpiride. A) The graphs represent the average amplitude and kinetics of train pulse-evoked DA levels measured in the presence of sulpiride (5 μM) alone (+74% above control, n = 7) or sulpiride in the presence of an elevated concentration of extracellular Ca2+ (3.4 mM) (+ 84% above sulpiride alone, n = 7). B) Summary graph showing the time course of the effect of an elevation of extracellular Ca2+ to 3.4 mM (for a total of 8 min) with pre-applied sulpiride (5 μM) in the bath (n = 7).
