How is the strength of a stimulus encoded by neurons?
A)By the size of action potentials
B)By the frequency of action potentials
C)By the duration of action potentials
D)By whether the action potential peak is positive or negative

Question

Quizplus · Accepted Answer

The strength of a stimulus is encoded by the frequency of action potentials. The stronger the stimulus, the greater the frequency of action potentials. Therefore, option B is the correct choice. The size, duration, and polarity of action potentials do not encode the strength of a stimulus.
