Neuralink Reports Malfunction in its First Brain Implant Inside a Human

[ad_1]

Neuralink, Elon Musk’s brain chip startup, reported a malfunction with its first-ever implant, the brain-computer interface (BCI) on Wednesday. The BCI was implanted into 29-year-old Nolan Arbaugh’s brain in January as part of a six-year trial. The chip aims to help patients with paralysis control technology using their mind. Unexpectedly, a number of threads retracted from Arbaugh’s brain, reducing the number of effective electrodes and hindering Neuralink’s ability to test the performance of the system. The company improved its recording algorithm, enhancing Arbaugh’s control accuracy. In response to the malfunction, removing Arbaugh’s implant was considered but ultimately deemed unnecessary as it posed no risk to his safety. However, the incident has improved Arbaugh’s performance, and he now uses the BCI system for up to 10 hours a day.
