Cellular neuroscience is the study of neurons at a cellular level.Repolarization of the membrane potential continues, resulting in an undershoot phase or absolute refractory period.The undershoot phase occurs because unlike voltage-gated sodium channels, voltage-gated potassium channels inactivate much more slowly.Briefly, the model states that the generation of an action potential is determined by two ions: Na and K .An action potential can be divided into several sequential phases: threshold, rising phase, falling phase, undershoot phase, and recovery.
