Responses of motor cortex neurons to visual stimulation in the alert monkey.
Evidence for visually evoked activity in single neurons of area 4 is presented. These neurons modulated their activity in relation to stimuli moving across the visual field of the monkey, without showing habituation. Some of them even had direction sensitivity. Their activity was independent of eye movements and unrelated to muscle contractions. The visually activated neurons were distributed throughout the depth of motor cortex.
