Action potential (summarized) | Action potential neuron | Action potential physiology
In this video we will learn how the action potential is generated, each of its phases, the importance of the gradients of sodium and potassium concentration, their equilibrium potentials, their conductances, the functioning of the channels through which they pass, and the terms threshold, depolarization, repolarization, hyperpolarization and refractory periods, enjoy this material.
