In neurophysiology Hyperpolarization is a change in a cell's membrane potential that makes it more negative. It is the opposite of a depolarization.Hyperpolarization is often caused by efflux of K+ (a cation) through K+ channels, or influx of Clâ (an anion) through Clâ channels. On the other hand, influx of cations, e.g. Na+ through Na+ channels or Ca2+ through Ca2+ channels, inhibits hyperpolarization.t is the opposite of a depolarization.
