WebThe magnitude of the graded potential is proportional to the strength of the stimulus. Hence, a strong stimulus might result in a 10mV change in the membrane potentials, while a weaker stimulus may produce only a 5mV change. Graded potentials are also localized to a small area of the cell membrane and are sometimes called local potentials. WebJul 17, 2015 · Graded potentials are initiated by a stimulus that vary in magnitude depending on the strength of the stimulus. (The stronger the stimulus the more gated channels open causing larger depolarisation). …
