Depolarization

In biology, depolarization is a decrease in the absolute value of a cell's membrane potential. Thus, changes in membrane voltage in which the membrane potential becomes less positive or less negative are both depolarizations.

Mitochondrial depolarization paradoxically decreases the cytoplasmic calcium elevation following glutamate addition, probably due to an enhanced calcium efflux from the cell.

This change in the membrane potential, called depolarization, will cause the voltage-gated sodium channels to open. Sodium ions will rush in, resulting in a rapid change in the charge.
