Figure 6 Fast-scan cyclic voltammetry data collected during stimulated exocytosis of a single PC12 cell. Cyclic voltammetry was performed in the two- electrode mode using an SSCE reference electrode for all measurements. A scan rate of 300 V/s was employed using a triangular wave form that was ramped between −0.5 and +1.0 V. (A) Average current within a 60-mV window of the peak oxidation potential of DA. Individual current spikes represent faradaic current. (B) Enlargement of the region between scans 600 and 800 showing two current transients used to generate voltammograms. (C) Background-subtracted voltammograms generated by subtracting the average signal of
