In 1802,[[Thomas Young]] introduced the concept of distributed neural coding in his classic [[trichromatic theory]] of colour vision. In his formulation, the combined response profile of only three retinal receptors ('''left'''), tuned to respond to a broad [[spectrum]] of light wavelength ('''right'''), can account for the representation of any color in the visible spectrum. P, Q, R, S, colour stimuli. ]] -->

'''Neural coding''' is a [[neuroscience]]-related field concerned with how sensory and other information is represented in the [[brain]] by [[neural network|networks]] of [[neurons]]. The main goal of studying neural coding is to characterize the relationship between the [[Stimulus (physiology)|stimulus]] and the individual or ensemble neuronal responses and the relationship among electrical activity of the neurons in the ensemble <ref name="Brown">Brown EN, Kass RE, and Mitra PP. 2004. Multiple neural spike train data analysis: state-of-the-art and future challenges. ''Nature Neuroscience'' 7:456-61</ref>. It is thought that neurons can encode both [[digital]] and [[analog]] information.<ref>[http://pop.cerco.ups-tlse.fr/fr_vers/documents/thorpe_sj_90_91.pdf Spike arrival times: A highly efficient coding scheme for neural networks], SJ Thorpe - Parallel processing in neural systems, 1990</ref>
