Neuralink, founded by Elon Musk, has successfully implanted its device in a second patient to help paralyzed individuals control digital devices using their thoughts.

The implant, featuring 1,024 electrodes, aims to aid those with spinal cord injuries.

The first patient, Noland Arbaugh, has shown significant improvement, now able to interact with his computer by thinking, after previously using a mouth stick.

Musk plans to extend the implants to eight more patients this year as part of clinical trials.
