Neuralink is a company that develops brain implants to help paralyzed people communicate and control devices with their thoughts.[1][2] The company announced in December 2022 plans for clinical tests of a chip inserted into the skull within six months.[1] The implant contains 64 flexible fibers thinner than a human hair that record and transmit brain signals to the application.[2] The first quadriplegic patient recently received an implant and is doing well, according to Elon Musk.[2][3] The study will last six years and will assess the functionality and safety of a device powered by a wirelessly rechargeable battery.[2] Rivals say Neuralink is holding back the development of useful medical devices in the field of brain implants.[original content] The first patient developed a problem a few weeks after the implant.[3]
