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.

biology,
depolarization refers to the event a
cell undergoes when its membrane potential grows more positive with respect to the extracellular solution.

cell whereby the inside of the
cell is made less negative relative to the outside than at the resting membrane potential.

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

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