Noland Arbaugh, a quadriplegic, demonstrated the use of Neuralink's Telepathy brain chip by controlling a mouse cursor and playing video games without physical movement.

The implant operates in the brain's movement control area, enabling device control through user intention alone.

Arbaugh also showed his ability to play online chess and pause music with the implant, indicating a range of potential applications.

While Arbaugh has recovered from the surgery, he notes that the technology still has issues to be resolved.

Neuralink has obtained FDA approval for human clinical trials and is currently recruiting for a six-year study.

The company has faced criticism over the death of animals during its testing phase.

Elon Musk, the founder of Neuralink, is optimistic about the future benefits for patients with severe paralysis, though the technology's long-term success remains to be seen.
