Complex cell receptive fields: evidence for a hierarchical mechanism

Receptive fields have been identified for neurons of the auditory system, the somatosensory system, and the visual system. The term receptive field was first used by Sherrington in 1906 to describe the area of skin from which a scratch reflex could be elicited in a dog.
