A hyperpolarization or depolarization event may simply produce a graded potential, a smallish change in the membrane potential that is proportional to the size of the stimulus.
repolarization. 1. the reestablishment of polarity, especially the return of a cell's membrane potential to resting potential after depolarization. 2. in cardiac physiology, the restoration of the cell to its maximal diastolic potential, represented by phase 0 to phase 3 of the action potential.(rÄ'pÅ-lÄr-i-zÄ'shÅ­n),. the reestablishment of polarity, especially the return of a cell's membrane potential to resting potential after depolarization. 2. in cardiac physiology, the restoration of the cell to its maximal diastolic potential, represented by phase 0 to phase 3 of the action potential.
