Quizplus · Accepted Answer

Blindsight is a phenomenon where an individual with damage to the primary visual cortex is unable to consciously perceive visual stimuli in their corresponding visual field, yet can still perform tasks such as accurately reaching for objects in their blind field. This suggests the existence of a second, non-conscious visual system, which is thought to be based in the superior colliculus and other subcortical structures. Therefore, humans appear to have dual visual systems.
