The absolute refractory period is the period of time during which a second action potential cannot be initiated, regardless of the strength of the stimulus. This is due to the inactivation of voltage-gated sodium channels, which are required for action potential generation. If these channels remained inactivated, the absolute refractory period would be longer than normal, because it would take longer for the channels to reset and become available for another action potential to occur.
