something being depolarized or going through the depolarization process. Physiology: A shift in permeability and migration of sodium ions to the interior causes the plasma membrane of a muscle or nerve cell to lose the difference in charge between the inside and outside. The gated sodium ion channels on the membrane of the neuron rapidly open during the depolarization phase, allowing sodium ions (Na+) that are present outside the membrane to rush into the cell.
