Quizplus · Accepted Answer

The fact that increasing excitatory signals above the threshold for neural activation does not affect the intensity of an action potential indicates that neurons have an "all-or-none" response, meaning that they either fire or they do not, with no in-between. This is known as the "all-or-none law" of neural firing. It is not related to the myelin sheath, glial cells, or genetics.
