blindsight A term used to indicate someone who is totally blind but yet is able, unconsciously, to locate an object on the basis of visual cues. It indicates a lesion which has destroyed the visual cortex but in which the retinotectal pathway to the superior colliculus remains unaffected. This pathway is not involved in conscious vision but receives some information from the retina. See retinotectal pathway. How to thank TFD for its existence?

| The kinds of displays that induce blindsight may fail to stimulate adequately parts of the cortex that take secondary roles in handling visual information and that probably orchestrate visual awareness, Kolb and Braun suggest. |
