Question

Quizplus · Accepted Answer

The frequency of action potentials is used by the central nervous system to determine the strength of a stimulus. As the intensity of the stimulus increases, the frequency of action potentials generated by the receptor neurons also increases, allowing the central nervous system to code for the magnitude of the stimulus.
