Brain-training may help blindsight patients, with blindness due by injury to the brain region responsible for vision, gain some vision, German researchers said.
Study leader Caspar Schwiedrzik of the Max Planck Institute for Brain Research says the research may help blindsight patients -- whose primary visual cortex has been damaged through a stroke or trauma so they cannot consciously see, although on some level their brains process their visual environment -- gain conscious awareness of what their minds can see.
"Our study suggests that it might in principle be possible for blindsight patients to recover some visual awareness, and thus our findings might open a venue for a new line of research and potential treatments for patients with acquired cortical blindness," Schwiedrzik says in a statement.
The study, published in the Association for Research in Vision and Opathalmology's Journal of Vision, says the brain is continuously adapting and can be trained to see consciously what previously was consciously unseen.
