Fig. 3.

The interplay of electroporation (the area above the dashed line threshold) and excitation (the area above the solid line threshold) for different pulse durations (10 ns-10 μs) and charging time constants (1–5 μs). The thresholds were calculated for a cathode-facing pole of a round cell with a 10-μm radius using Eq. 3. The excitation thresholds are plotted only to the limit where the time for charging to 20 mV is under 200 ns. See text and Fig. 2 for details.
