Noland Arbaugh, a 29-year-old patient paralyzed below the shoulder after a diving accident, played chess on his laptop and moved the cursor using the Neuralink device.

Musk announced last month that the subject was able to control a computer mouse.

Referring to the implant procedure in the video posted on X, Arbaugh said, "The surgery was extremely easy. I was actually discharged from the hospital a day later. I don't have any cognitive impairment."

Neuralink aims to enable the use of all electronic devices through thought alone, thanks to the brain chip.

In the first phase, it is only being tested on patients who cannot use their limbs.

The Neuralink company aims to find solutions to neurological problems by connecting the human brain with a computer.

With chips implanted in the human brain, it aims to cure diseases such as dementia, Parkinson's and spinal cord injuries.

In May last year, Neuralink received approval from the United States Food and Drug Administration for human trials of the brain chip project.
