39% of electrodes work after second 'successful' human Neuralink implant

Elon Musk claims Neuralink has implanted a second human volunteer with its experimental N1 brain-computer interface (BCI) and that it's "working very well." But like the coin-sized device within the company's first patient, only a fraction of the electrodes are reportedly functioning properly. "I don't want to jinx it but it seems to have gone extremely well with the second implant," Neuralink's CEO said during an August 2 podcast interview with computer scientist, Lex Fridman. "A lot of electrodes" is arguably a relative number, however. During his lengthy conversation with Fridman, Musk clarified that while initial results appear "so far, so good," he estimates only roughly 400 of the BCI's 1,024 electrodes surgically implanted into the user's motor cortex are currently providing signals.
