Scientists sent patterns of electricity coursing across people’s brains so they could see letters that weren’t there, LiveScience reported.
The experiment reportedly worked in both sighted people and blind participants who had lost their sight in adulthood, according to the study, published May 14 in Cell. Although this technology is in its early stages, researchers predict that implanted devices could potentially stimulate brains to partially restore vision in the future.
The implants, or “visual prosthetics” were situated on the visual cortex and then stimulated in a pattern to “trace” out shapes that the participants could then “see,” Live Science wrote.
“An early iteration [of such a device] could provide detection of the contours of shapes encountered,” study authors neuroscientist Michael Beauchamp and neurosurgeon …continued .
