Neural coding

Neural coding is a neuroscience-related field concerned with characterizing the relationship between the stimulus and the individual or ensemble neuronal responses and the relationship among the electrical activity of the neurons in the ensemble. Based on the theory thatsensory and other information is represented in the brain by networks of neurons, it is thought that neurons can encode both digital and analog information.
