When voltage of a plasma membrane shifts from +30mV towards 0mV, we say cell is repolarizing. Repolarization results from the movement of positively charged K+ ions out of the cell. This repolarization phase of an action potential results in hyperpolarization, attainment of a membrane potential that is more negative than the resting membrane potential.
