Unformatted text preview: 20 msec and Iappl = 53 µA/cm2, the results are plotted below for Vm and the gating probabilities, m3, n4 and h. After application of the current, there is a rise in the potential and a short plateau at  ­50 mV. At this point the leakage gate closes and the Na+ gate rapidly opens, initiating an action potential. The K+ gate opens more slowly peaking after the Na+ gate starts to close and during repolarizaton. The Na+ conductance is narrower than the channel gating because the conductance is the product of m3h. The Na+ and K+ current are very similar and opposite in sign, indicating a net ion movement in the opposite...
