Can blindsight be superior to 'sighted-sight'?
DB, the first blindsight case to be tested extensively (Weiskrantz, 1986) has demonstrated the ability to detect and discriminate a range of visual stimuli presented within his perimetrically blind visual field defect. In a temporal two alternative forced choice (2AFC) detection experiment we have investigated the limits of DB's detection ability within his field defect. Blind field performance...
متن کاملFrom blindsight to sight: cognitive rehabilitation of visual field defects.
PURPOSE Traditionally, post-chiasmatic lesions were believed to result in complete and permanent visual loss in the topographically related areas of the visual field. However, a number of studies with monkeys, and later with humans, have demonstrated spared implicit visual functioning, referred to as 'blindsight'. The present study assessed whether training this phenomenon would induce an objec...
متن کاملBlindsight
important for screening purposes, but have to be combined with detailed biochemical and functional studies. In fact, the experience with yeast showed that the many possibilities offered by genomics and proteomics shifted the emphasis from cloning back to biochemistry and thus gave us more time for functional studies. What is the biggest hindrance to science? Administrators who like paragraphs m...
متن کاملFacial blindsight
Blindsight denotes unconscious residual visual capacities in the context of an inability to consciously recollect or identify visual information. It has been described for color and shape discrimination, movement or facial emotion recognition. The present study investigates a patient suffering from cortical blindness whilst maintaining select residual abilities in face detection. Our patient pr...
متن کاملColor Experience in Blindsight
Blindsight, the ability to blindly discriminate wavelength and other aspects of stimuli in a blind field, sometimes occurs in people with lesions to striate (V1) cortex. There is currently no consensus on whether qualitative color information of the sort that is normally computed by double opponent cells in striate cortex is indeed computed in blindsight but doesn’t reach awareness, perhaps owi...
