Review of results from Orion study

Scientists have long dreamed of restoring vision in blind individuals by stimulating the visual cortex, bypassing malfunctioning eyes to directly deliver information to higher visual centers (Bosking et al., 2017). Beauchamp et al. (2020) used electrical stimulation of the visual cortex to produce visual percepts in blind human subjects, using innovative current steering and sequential stimulation techniques to create recognisable shapes such as letters of the alphabet. In our review of Beauchamp et al.’s work, ‘Writing to the Mind’s Eye of the Blind,’ published in Cell, we discuss their ground-breaking results, and their implications for the field of visual cortical prosthetics:
