Question

Quizplus · Accepted Answer

The absolute refractory period is the time during which the neuron is unable to generate another action potential, no matter how strong the incoming stimulation is. This is due to the fact that the sodium channels that open during an action potential become inactivated and cannot be opened again until they have returned to their resting state. Therefore, Owantu was unable to stimulate those neurons for a brief time after their firing due to the absolute refractory period.
