FREMONT, Calif. — Neuralink is opening its Blindsight vision study to a new group of volunteers, the company said, a step that moves its effort to restore sight from a single landmark case toward a broader clinical program.
The expansion comes just days after Neuralink reported a historic milestone: its first Blindsight patient perceived points of light generated directly by the implant, bypassing the eyes entirely. That result validated the core idea behind the device — that stimulating the visual cortex can create the sensation of sight even in people who have been blind for years.
From One Patient to Many
Enrolling additional participants lets Neuralink test the implant across a wider range of cases and gather the data regulators will want to see before any broader authorization. The company said it is looking for volunteers who have lost vision in both eyes but whose visual cortex remains healthy — the profile most likely to benefit from direct cortical stimulation.
Early Blindsight vision is deliberately simple, a grid of light points rather than a full picture. But Neuralink has said resolution should climb steadily as electrode counts rise and its software learns to translate camera input into richer patterns the brain can interpret.
