... Caption: Three types of stimuli that Hubel and Wiesel (1959, 1965) found caused neurons in the cat cortex to respond. Neurons responded to bars with a specific orientation, to bars with a specific orientation moving in a particular direction, and bars of a particular length moving in a particular d ...

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.
