The generation of an action potential occurs in three stages: (1) depolarization, which changes the membrane potential from -60 mV to +40 mV primarily through sodium influx; (2) repolarization, which returns the membrane to its resting potential primarily through potassium efflux; and (3) after-hyperpolarization, which involves recovery from a slight overshoot of the repolarization phase.
