Neuralink Receives FDA Approval for Second Human Brain-Computer Interface Implant as 85% of Electrodes in First Patient Shifted

According to local media reports, on May 20, the FDA approved Elon Musk’s testing of the brain-computer interface on a second subject and addressed the issues experienced by the first subject, Noland Arbaugh.Topic.
In February this year, while discussing the latest updates on Neuralink’s first human brain-computer interface trial, Musk stated, “Progress is going well; the volunteer appears to have fully recovered, with no known adverse neurological effects, and is able to control cursor movement on the screen through thought.”(Click to review:Paralyzed for 8 Years, Now Able to Game All Night: Update on the First Recipient of Musk’s Brain-Computer Interface）
Earlier this month, Neuralink stated on its official website that in the weeks following Arbaugh’s surgery, many wires had retracted from the brain, resulting in a net reduction in the number of functional electrodes. Subsequently, researchers modified the algorithm for decoding neuronal signals, thereby improving the bits-per-second (BPS) rate.
Additionally, it is reported thatOnly about 15% of the electrode wires in Arbaugh’s brain implant chip are functioning properly; 85% of the wires have shifted, and many threads that are unable to receive signals have been deactivated.
According to reports, Neuralink is expected to implant its device in a second participant in June, with a total of 10 implants planned for this year. More than 1,000 individuals with quadriplegia have already signed up for the participant registry. Neuralink also plans to submit applications to regulatory authorities in Canada and the United Kingdom in the coming months to conduct similar trials.
