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.
depolarization of the membrane, this will diminish the magnitude of the resting membrane. potential and will depolarize the cell at electrode #2. No change will be observed in the. membrane potential at electrode #3 unless electrode #3 is within a few mm of electrode #2.
