Neuralink, a company co-founded by Elon Musk, has successfully implanted a second brain-computer interface device into a human subject, Nature reported Aug. 6.
During a podcast released Aug. 2, Mr. Musk said the new implant is functioning well, with around 400 of its 1,042 electrodes actively transmitting signals from the person's brain.
Although details regarding the recipient or the specifics of the surgery were not disclosed, Mr. Musk said the individual, similar to the first recipient, suffers from a spinal cord injury.
The procedure comes after Neuralink's first patient had a number of threads on the implant retracted from his brain shortly after the surgery.
