FREMONT, Calif. — Neuralink is preparing for one of the most ambitious experiments in its history: implanting its Blindsight device in a fully blind human for the first time, a step that could begin restoring a form of vision through a chip placed directly in the brain.
Company founder Elon Musk has said Neuralink is ready for the procedure and is awaiting final regulatory clearance. If approved, it would extend the company's work from helping paralyzed patients control computers to giving sight to people who have lost it entirely — or never had it.
How Blindsight Works
Blindsight bypasses the eyes and optic nerve altogether. A camera captures the scene, and processed signals are transmitted wirelessly to an implant embedded in the brain's primary visual cortex, where an array of electrodes stimulates neurons to create points of light called phosphenes.
Researchers describe the first experience as something like early video-game graphics — a grid of bright and dark dots that the brain gradually learns to interpret. Crude at first, the resolution is expected to climb sharply as the hardware advances, with Neuralink already developing a next-generation implant carrying roughly three times the channel count of today's device. The same rapid iteration that has defined Neuralink's expanding Telepathy trials is now being aimed at vision.
