Question

Quizplus · Accepted Answer

As the strength of a stimulus is increased, the frequency of occurrence of action potentials increases. This is known as the principle of neural coding. The strength of a stimulus is coded by the frequency of action potentials rather than the amplitude or height of the action potential.

As the Strength of a Stimulus Is Increased, the
