Different Membrane Pathways Mediate Ca²⁺ Influx in Adrenal Chromaffin Cells Exposed to 150–400 ns Electric Pulses

Figure 1

nsPEF exposure of chromaffin cells. (a) Photomicrograph of a chromaffin cell located at the center of the gap between the electrode tips. (b) Traces of a 150, 200, and 400 ns pulse (65 V applied to the electrodes to yield an -field of 3.1/kVcm) captured by an oscilloscope. (c) Computed -field distribution in the vicinity and at the location of an exposed cell. The dotted box represents the region over which a cell can be located in experiments.
