The restoration of a polarized state across a membrane.
| Veterinary Dictionary: repolarization |
The re-establishment of polarity, especially the return of cell membrane potential to resting potential after depolarization.
| Wikipedia: Repolarization |
In neuroscience, repolarization refers to the change in membrane potential that returns the membrane potential to a negative value after the depolarization phase of an action potential has just previously changed the membrane potential to a positive value. Repolarization results from the movement of positively charged potassium ions out of the cell. Typically the repolarization phase of an action potential results in hyperpolarization, attainment of a membrane potential that is more negative than the resting potential.
