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

Figure 3

Representative bright field images of cells before and after exposure to a 150, 200, and 400 ns pulse. Each pulse was applied at an -field of 3.1 kV/cm and images were captured before 0 s and 50 s after the pulse.
