The scenario
A neuron at resting membrane potential receives a stimulus. If the stimulus depolarizes the membrane to threshold, voltage-gated sodium channels open, initiating an action potential. The flowchart maps the sequence of depolarization, repolarization, and hyperpolarization ending with the restoration of resting potential.
