The neurobiology of blindsight.
نویسندگان
چکیده
Some patients can respond to visual stimuli presented within their clinically absolute visual field defects that have been caused by partial destruction of striate cortex. This puzzling phenomenon of looking, pointing, detecting and discriminating without seeing has been called blindsight, and has fascinated philosophers and neuroscientists alike as a spotlight on the nature of unconscious or covert awareness, and the means it provides of studying the visual information carried by pathways other than the major route through the striate cortex.

Blindsight revisited.
Some human patients with lesions to their primary visual (striate) cortex (V1) demonstrate residual visual capacity, but without acknowledged perceptual awareness. This phenomenon has been termed blindsight. Recent results from work on blindsight patients suggest that it is unlikely to be attributable to intact residual areas (tags) of V1. Previous research has reported that blindsight patients...
متن کاملNeural substrates of blindsight after hemispherectomy.
Blindsight is a visual phenomenon whereby hemianopic patients are able to process visual information in their blind visual field without awareness. Previous research demonstrating the existence of blindsight in hemianopic patients has been criticized for the nature of the paradigms used, for the presence of methodological artifacts, and for the possibility that spared islands of visual cortex m...

the left half of both eyes. Although his defect improved considerably, he was left with a chronic scotoma that occupied mainly the left lower quadrant. It was in this visual field that Weiskrantz performed experiments, described in Part II, which led him to advocate blindsight. Subjects like D. B. deny the ability to see in a 'destriated' field, and are diagnosed as blind in that region accordi...
متن کاملUnconscious vision: new insights into the neuronal correlate of blindsight using diffusion tractography.
The existence of several types of unconscious vision, or 'blindsight', has convincingly been demonstrated in numerous studies, and their neuronal correlates have been hypothesized according to the nature of the residual vision observed. We used diffusion tensor imaging (DTI) tractography to demonstrate an association between the presence of 'Type I'- blindsight or 'attention blindsight' and rec...

In this introductory paper, we assess the current status of blindsight — the phenomenon in which patients with damage to their primary visual cortex retain the ability to detect, discriminate and localize visual stimuli presented in areas of their visual field in which they report that they are subjectively blind. Blindsight has garnered a great deal of interest and critical research, in part b...
