The nervous system codes for variation in the intensity of incoming sensory stimuli by variations in the _______ of a neuron.
A) repolarization rate
B) resting membrane potential
C) speed of conduction of action potentials
D) total amplitude of the action potential
E) firing rate

Question

Quizplus · Accepted Answer

The firing rate of a neuron, or how frequently it sends action potentials, corresponds to the intensity of an incoming sensory stimulus. As stimulus intensity increases, the firing rate of the neuron also increases, allowing for coding of the varying levels of intensity.
