Action Potentials - Foundations of Neuroscience Action Potentials. As covered in Chapter 1, the action potential is a very brief change in the electrical potential, which is the difference in charge between the inside and outside of the cell. During the action potential, the electrical potential across the membrane moves from a negative resting value to a positive value and back. 12.5 The Action Potential - Anatomy & Physiology Figure 12.5.7 - Graph of Action Potential: Plotting voltage measured across the cell membrane against time, the action potential begins with depolarization, followed by repolarization, which goes past the resting potential into hyperpolarization, and finally the membrane returns to rest.
