Blindsight

This article is about the neurological phenomenon. For other uses, see Blindsight (disambiguation).

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.[1] The term was coined by Lawrence Weiskrantz and his colleagues in a paper published in a 1974 issue of Brain.[2] A previous paper studying the discriminatory capacity of a cortically blind patient was published in Nature in 1973.[3] The assumed existence of blindsight is controversial, with some arguing that it is merely degraded conscious vision.[4][5][6]
