Question

Quizplus · Accepted Answer

Action potentials are generated in an all-or-none fashion, meaning they either occur fully or not at all. The strength of the incoming stimulation affects the frequency of action potentials, not their amplitude or size. Action potentials also travel at a constant speed regardless of the intensity of the incoming stimulation.
