Question

Quizplus · Accepted Answer

Stimulus intensity is represented in a single neuron by the firing rate of the action potentials. When the stimulus is stronger, the neuron will fire action potentials more frequently, and when the stimulus is weaker, the neuron will fire action potentials less frequently. The size of the action potentials and the synapse do not necessarily reflect stimulus intensity. Firing rate of the neurotransmitters is also not a measure of stimulus intensity in a single neuron.
