Rate Coding - Glossary Term Illustration

Rate Coding

Rate coding, also known as frequency coding, is a model of neuronal communication that describes how the intensity of a stimulus affects the rate of action potentials. This glossary term explains the all-or-none principle and how additional information is coded in the frequency of action potentials. Rate coding was first shown by ED Adrian and Y Zotterman in 1926.

Rate Coding

Rate Coding: Rate coding, sometimes called frequency coding, states that as intensity of a stimulus increases, the rate of action potentials increases. Rate coding is a model describing a type of neuronal communication which implies the amplitude and shape of an action potential may be relatively fixed (all-or-none principle) with additional information coded in the frequency of action potentials.
