The instantaneous value of the potential observed between excited and resting portions of a cell or excitable living structure. Note : It may be measured direct or through a volume conductor. 2. The electrical response of an excitable membrane that leads to the propagation of a nerve impulse. IEEE Std. 539-1990 3. Voltage produced across a nerve cell membrane by a stimulus. It arises from the entry of sodium ions across the cell membrane, which results in membrane depolarisation.
