Visual experience and blindsight: a methodological review

Exp Brain Res. 2011 Apr;209(4):473-9. doi: 10.1007/s00221-011-2578-2. Epub 2011 Feb 15.

Abstract

Blindsight is classically defined as residual visual capacity, e.g., to detect and identify visual stimuli, in the total absence of perceptual awareness following lesions to V1. However, whereas most experiments have investigated what blindsight patients can and cannot do, the literature contains several, often contradictory, remarks about remaining visual experience. This review examines closer these remarks as well as experiments that directly approach the nature of possibly spared visual experiences in blindsight.
