WebAs the action potential passes through, potassium channels stay open a little bit longer, and continue to let positive ions exit the neuron. This means that the cell temporarily hyperpolarizes, or gets even more negative than its resting state. As the potassium channels close, the sodium-potassium pump works to reestablish the resting state. ... WebThe stages of an action potential are: 1. Resting potential 2. Depolarization 3.

At rest, the Vm of a neuron is around −70 mV (closer to the equilibrium potential for potassium, VK ), but during an action potential, Vm transiently approaches +50 mV (closer to the equilibrium potential for sodium, VNa ).
