This groundbreaking procedure enables him to operate a computer cursor using thoughts, allowing him to play online video games. 

In a nine-minute presentation, Neuralink engineer Bliss Chapman introduced the patient, Noland Arbaugh, who suffered a spinal cord injury in a "freak diving accident" eight years ago. 

"I'm paralyzed below the shoulders. I have no sensation or movement below my level on injury," Arbaugh said.

Chapman shows how Arbaugh uses his mind to move a cursor around a screen to play a game of chess.

It feels like "I'm using the Force on a cursor," Arbaugh said, referring to the movie Star Wars. 

In a post on X, Musk reposted the Neuralink broadcast, commenting: "Livestream of Neuralink demonstrating "Telepathy" – controlling a computer and playing video games just by thinking."

In January, Musk posted on X that the first patient received the brain chip implant, specifying that the person was recovering well. Since then, Arbaugh has learned to play Civilization VI with his mind-controlled cursor.

Even though brain-computer interface research has existed for decades, there's been a more recent push by billionaires, including Musk, to invest in the technology and further develop it. 

Neuralink is powered by a quarter-sized chip implanted in the skull with electrodes inserted into the brain.
