Question

Quizplus · Accepted Answer

The intensity of a stimulus can be determined by population coding and/or frequency coding. Population coding refers to the activation of a group of neurons that collectively encode the intensity of a stimulus. Frequency coding, on the other hand, refers to the rate of action potential firing in individual neurons, which increases with increasing stimulus intensity. Therefore, both population coding and frequency coding can be used to determine the intensity of a stimulus within the central nervous system. Labeled line coding, which refers to the specific pathway by which sensory information is transmitted to the brain, is less relevant to the determination of stimulus intensity.
