The '''rate coding''' model of [[neuron]]al firing communication states that as the intensity of a stimulus increases the [[frequency]] or '''rate''' of [[action potential]]s, or "spike firing", increases.

This [[phenomenon]] was originally shown by ED Adrian and Y Zotterman in 1926.{{ref|Adrian}} In this simple experiment different weights were hung from a [[muscle]]. As the weight of the stimulus increased, the number of spikes recorded also increased. From these original experiments Adrian and Zotterman concluded that action potentials were unitary events, and that the frequency of events, and not individual event magnitude, was the basis for most inter-neuronal communication.
