Abstract

Transient inactivation of the superior colliculus in primates during a motion-change-detection task is shown to lead to large deficits in visual attention while the enhanced response of neurons in the visual cortex to attended stimuli remains unchanged; this shows that processes independent of those occurring in the visual cortex have key roles in visual attention.
