Which of the following cannot be used for signaling the intensity of a stimulus?
A) the type of neuron activated (e.g., low vs. high threshold neurons)
B) the number of neurons activated
C) amplitude of action potentials
D) the frequency of firing along axons

Question

Quizplus · Accepted Answer

The amplitude of action potentials cannot be used to signal the intensity of a stimulus because the amplitude of action potentials is constant due to the all-or-none principle. The intensity of a stimulus is instead conveyed by the type of neuron activated, the number of neurons activated, and the frequency of firing along axons.
