Depolarization triggers capacitance transients indicative of vesicular release. Membrane capacitance was monitored by applying a 1 kHz sinusoidal voltage command (bottom). A brief (100 ms) depolarizing step produces a fast rise in membrane capacitance, followed by a slow decline back to its baseline level. Similar results were seen in eight cells.
