Deviation code is a prospective candidate of the communication between adapting neurons

The low Firing Rate (FR) of pyramidal cells (Thorpe et al., 1989, Pettigrew et al., 1968) prevents the use of rate coding. The Deviation Code (DC), in which the deviation from the mean is the signal, is a candidate code that may be used in neurobiological and formal neural networks. The neurons which use this code could have similar properties as the model neurons frequently used by the neural network (NN) theories. The biological verification of this type of coding is required. This coding might be relevant in the physiological investigation of learning rules and can help to understand the organization of different nuclei of the nervous system.
