... Voltage-gated Na+ channels have a refractory period during which they cannot open. Na+ channels have two gates: • An activation gate is closed at rest but opens quickly at threshold. • An inactivation gate is open at rest and closes at threshold but responds more slowly. The gate reopens 1–2 milli ...
