“LeBrain James”

Neuralink patient 23 goes by “LeBrain James” (@LeBrainJames023) on X, a play on LeBron James, who has usually worn the number 23. He has not made his real name public. He is 35 years old as of September 2026 (self-stated) and has been paralyzed for about 9 years as of that post. In September 2026 he took his robotic arm to an Ohio State game.
