Since all action potentials are identical, the intensity of a sensation depends on:
A) whether a myelinated or unmyelinated neuron has been stimulated.
B) the duration of the stimulation.
C) whether the neuron stimulated is a pre- or postsynaptic neuron.
D) the total number of neurons stimulated and the frequency of their discharge.
E) the presence of an EPSP or IPSP, which allows for a graded response.

Question

Quizplus · Accepted Answer

The intensity of a sensation is determined by the number of neurons stimulated and the frequency of their action potentials, not by the characteristics of individual action potentials, which are all-or-nothing events.

Since All Action Potentials Are Identical, the Intensity of a Sensation
