Na+ Uptake Triggered in Adrenal Chromaffin Cells by a 5-ns Electric Pulse is Facilitated by Ca2+ Influx Via an L-Type-Like Ca2+ Channel Independent of Changes in Membrane Potential

{{output}}
Whole-cell voltage patch clamp studies have shown that in bovine adrenal chromaffin cells held at -70 mV, a single 5-ns, 5 MV/m pulse activates a membrane conductance carried partially by Na+ through TRPC4/5 channels and the sodium leak channel (NALCN). Here w... ...
