The action potential is the brief electrical impulse that is responsible for the propagation of information down the axon of a neuron. Some important concepts involved with the action potential are the membrane potential, resting potential, threshold.hen the membrane potential reaches its peak, the action potential is attained, and the sodium channels become refractory and no more sodium ions enter the cell. Potassium ions continue to leave the cell, and the membrane potential slowly decreases towards the resting potential.
