Unformatted text preview: and there is a small change in gating probabilities. At 25 µA/cm2, an action potential is produced. Relative to the result at higher currents, the action potential takes loner to start and ends slightly later. Correspondingly, the gating probabilities do not change very much for currents below the threshold. Once the threshold is reached, the gating probabilities rise dramatically. Above the threshold, the gates open earlier but the magnitude of the change is similar. 60 1 Iapp = 25 0. 8 20 0 Gating Probabilities Membrane Potential, mV Na+ 0. 9 40 Iapp = 85 0. 7 Iapp = 5 Iapp = 15...
