Membrane Potential - an overview ScienceDirect Topics

WebAny depolarization that does not change the membrane potential to −55 mV or higher will not reach threshold and thus will not result in an action potential. Also, any stimulus that depolarizes the membrane to −55 mV or beyond will cause a large number of channels to open and an action potential will be initiated.
