Elon Musk’s Neuralink, a startup focused on developing brain-computer interfaces (BCIs), has recently been granted FDA Breakthrough Device Designation for its new product, Blindsight. Blindsight is an innovative implant designed to restore vision for individuals who are blind, targeting the visual cortex in the brain.
The core function of Blindsight involves implanting a microelectrode array into the visual cortex, which is the part of the brain responsible for processing visual information received from the retinas. Once implanted, this array activates neurons that ideally create visual images for the individual. Musk has highlighted that this technology could potentially aid individuals who have lost sight completely, including those whose blindness originates from birth or involves damage to both eyes and the optic nerve.
According to Musk, the initial phase of the vision provided by Blindsight will be basic and low-resolution, akin to “Atari graphics.” However, he envisages progressive improvements where the resolution could surpass natural human vision. Advanced capabilities might include seeing in different wavelengths such as infrared, ultraviolet, or even radar, reminiscent of the Star Trek character Geordi La Forge.
Currently, Neuralink is recruiting participants for its PRIME study, which is another of its clinical trials. This trial focuses on a BCI designed specifically for individuals with quadriplegia, aiming to enable them to control digital devices purely through thought. The BCI technology by Neuralink has already been tested successfully in a human patient earlier this year, with reported functions including playing video games and engaging in online chess.
This development reflects Neuralink’s broader mission, which is stated on their website as aiming to “create a generalized input/output platform capable of interfacing with every aspect of the human brain.” Such a platform would not only assist in medical rehabilitation but could revolutionize the way individuals interact with technology and possibly between each other.
In a similar vein in the BCI industry, Boston-based Neurable announced a partnership with Healthspan Digital, a Canadian precision health company, earlier in March. They plan to distribute neurotechnology globally to health and longevity clinics, which will help in assessing cognitive performance and brain health through advanced technological means.
In addition to these developments, it’s worth noting that this field is gaining significant attention, highlighted by events such as the HIMSS Healthcare Cybersecurity Forum scheduled for late October and early November in Washington, D.C.
Overall, Neuralink’s advancements and the FDA’s recognition of Blindsight as a breakthrough device not only mark significant milestones in neural technology but also pave the way for revolutionary changes in how visual impairments and possibly other neurological conditions might be treated in the future.
