WebThe return of the membrane potential to the resting potential is called the repolarization phase. There is also a phase of the action potential during which time the membrane … WebThe undershoot is the time when the membrane potential is hyperpolarized relative to the resting potential. 2. During the rising phase of an action potential, the membrane potential changes from negative to positive. In the figure, the rising phase is from approximately 1 to 2 milliseconds on the graph.
