Detailed explanation-1: -Blindsight is a classic neurological phenomenon that can shed light on this question [1–3]. Typically damaged in the primary visual cortex, these patients claim to have no conscious visual experience when static visual stimuli are presented to their subjectively ‘blind’ field.

Detailed explanation-2: -Blindsight is the ability of people who are cortically blind to respond to visual stimuli that they do not consciously see due to lesions in the primary visual cortex, also known as the striate cortex or Brodmann Area 17.

Detailed explanation-3: -Blindsight is defined by the Oxford Concise Dictionary as “Medicine: a condition in which the sufferer responds to visual stimuli without consciously perceiving them, ” implicitly referring, of course, to human patients. The historical origins, however, stem from animal research and neuroanatomy.

Detailed explanation-4: -Blindsight is a phenomenon in which patients with damage in the primary visual cortex of the brain can tell where an object is although they claim they cannot see it. Scientists now provide compelling evidence that blindsight occurs because visual information is conveyed bypassing the primary visual cortex.
