Neural selectivity is the modulation of the electrophysiological activity of a neuron as a function of the sensory stimulus (e.g., sound) or, more generally, any other information processed by the nervous system.

A classic example of neuronal selectivity is the mode of response of so-called simple neurons of the primary visual cortex. The rate of discharge of action potentials of these neurons varies according to the orientation of the visual stimuli: each neuron responds in a maximal way for the lines having a particular orientation. For example, one neuron will have a maximum response for vertically oriented visual stimuli, while another will respond mainly for visual stimulations oriented at 30 ° to the horizontal and very little for different orientations.
