- It states that as intensity of a stimulus increases, the rate of action potentials increases - rate coding is sometimes called frequency coding. 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.
