Saliency maps have been proposed to guide visual attention, yet the underlying neural correlates remain undetermined. Here, the authors record from monkeys as they watch videos of natural scenes, and find superior colliculus superficial visual-layer neurons exhibit activity patterns consistent with a visual saliency map.
