WebSep 4, 2024 · Figure 11.4. 4 shows the change in potential of the axon membrane during an action potential. The nerve goes through a brief refractory period before racing resting potential. During the refractory period, another action potential cannot be generated. In myelinated neurons, ion flows occur only at the nodes of Ranvier.
