What does the central nervous system use to determine the strength of a stimulus?
A) size of action potentials
B) origin of the stimulus
C) type of stimulus receptor
D) frequency of action potentials

Question

Quizplus · Accepted Answer

The central nervous system determines the strength of a stimulus based on the frequency of action potentials sent by sensory neurons. A stronger stimulus will generate a higher frequency of action potentials, and a weaker stimulus will generate a lower frequency of action potentials. Therefore, choice D (frequency of action potentials) is the best answer.
