What are 3 effects of Em on Na+ inactivation?
|
1) Na+ channel inactivation is increased by depolarization
2) Na+ channel inactivation is decreased by hyperpolarization 3) hyperpolarizng pre-pulses (from resting Em) increase Na+ current during 'test' depolarization |

how does peak conductance depend on voltage?
|
as voltage increases, so too does peak (Na) and steady state (K) conductance
