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

Figure 8

Effect of Cd²⁺ on the Ca²⁺ response of the cells to a 150 ns pulse. Results are plotted as the averaged cell responses ± SE for cells exposed to a 150 ns pulse at 3.1 kV/cm in the absence and presence of 200 μM Cd²⁺. Cells were pretreated for 30 min with Cd²⁺ before exposure. The arrow indicates when the pulse was delivered to the cells ( 8–11).
