Quizplus · Accepted Answer

The relative refractory period occurs after the absolute refractory period, during the repolarization phase of the action potential, when the neuron can fire again but requires a stronger stimulus. This typically corresponds to the period when the membrane potential is returning to its resting state, often represented as phase 4 in diagrams.
