If action potentials are all-or-nothing, then how is the intensity of the stimulus coded into action potentials?
a. intense stimuli produce more intense action potentials
b. intense stimuli produce higher frequency of action potentials
c. intense stimuli result in a reduction in the number of action potentials produced.
d. there is a separate neuronal network that codes for stimulus intensity.
e. the body does not code of stimulus intensity

The correct answer is option b.

Explanation:

The production of higher frequency of action potentials by the intense stimuli is known as frequency coding. It is a procedure by which the CNS, restricted by the all or none characteristics of conduction of nerve impulse, possesses the tendency to convey information about changing the intensity of signals. It performs this by imparting frequency modulation. The frequency of impulses changes with the strength of the stimulus.
