Barrow has helped standardize brain implant surgeries in which the patient can remain asleep, a key step in making it more acceptable to a broad set of the population, Ponce said. This is in line with Musk's vision for Neuralink's brain chip. The billionaire CEO of Tesla Inc and majority owner of Twitter has said Neuralink's brain implants will become as ubiquitous as Lasik eye surgery. Neuralink's implant is a brain computer interface (BCI) device, which uses electrodes that penetrate the brain or sit on its surface to provide direct communication to computers. So far, no company has received U.S. approval to bring a BCI implant to the market.
