Neuralink has revealed some issues with its Link brain implant, a cutting-edge “Brain-Computer” interface designed to assist individuals with paralysis in operating a computer using their thoughts. The implant features 1,024 electrodes situated on 64 threads that are thinner than a human hair.
The first recipient of the implant was 29-year-old Niland Arbo, and according to Neuralink, the procedure was deemed “highly successful.” However, there have been recent concerns as some threads from the patient’s brain shifted, resulting in a decrease in the number of functioning electrodes and a reduction in the effectiveness of the Link measurements.
After encountering these issues, Neuralink took steps to update the recording algorithm, enhance the user interface, and optimize the signal conversion methods for cursor movement. While the company contemplated removing the implant, the problems were not considered directly life-threatening to Arbo.
Despite the challenges, Arbo reportedly uses the system for around 8 hours on weekdays and up to 10 hours on weekends. He described his experience with the implant as “a luxurious overload” and emphasized how it has helped him to “reconnect with the world.”
