Organisms can perceive different intensities of a stimulus by

a. an increase in the frequency of action potentials of an afferent neuron.
b. an increase in intensity of the action potentials of an afferent neuron.
c. an increase in the numbers of afferent neurons generating action potentials.
d. an increase in intensity and frequency of action potentials as well as an increase in the
number of cells generating action potentials.
e. an increase in the frequency of action potentials generated by an afferent neuron as well as
an increase in the numbers of afferent neurons generating action potentials, but without
any change in the intensity of individual action potentials generated by the neurons.
