In the video, posted on Musk’s social media site X, the patient said his name was Noland Arbaugh, 29, and had become paralyzed from the shoulders down after a diving accident about eight years ago. Arbaugh said he loved playing chess, and the video appeared to show him moving the cursor to play computer chess.

The Post could not independently verify the claims made in the video. Neuralink did not immediately respond to a request for comment.

Neuralink’s device and rival products are designed to read brain activity to decipher what movement a person intends to make, and then run a command to execute that action. Arbaugh said initially he practiced attempting to move his hand until it became intuitive to imagine moving the cursor.

“Basically it was like using the force on the cursor,” he said in the video, an apparent reference to Star Wars, adding that he’s used the implant to play a video game as well.

The video of Arbaugh comes nearly three years after Neuralink posted a video showing a monkey playing Pong with its mind. (The company has come under fire for its treatment of animals in developing its brain implant).

Neuralink isn’t the first company to introduce an electronic implant that allows a person to move a cursor by thinking about it. Synchron, a rival, is developing a stent-like device that rests atop the brain’s motor cortex and has enabled patients to type messages using their thoughts, sometimes assisted by eye-tracking software.

Neuralink has taken a more invasive approach in the hopes that it will transfer data from the brain to the computer faster than rival technologies. The company has said it uses a robotic device to sew an electrode-laden computer chip into the surface of the brain. Musk has said that the initial application of the device is to help paralyzed patients recover function, but also envisions it one day enhancing the capability of healthy people.
