Elon Musk says one of his startups has a monkey with wires going into its brain that’s able to play video games, RIA Novosti reported, citing Bloomberg.

“He’s a happy monkey,” said Musk, the chief executive officer of electric-vehicle maker Tesla Inc. and backer of numerous other futuristic projects, including Neuralink Corp., a startup focused on developing a brain-computer interface. He said videos of the plugged-in simians would be released soon, perhaps in around a month.

“We have a monkey with a wireless implant in their skull with tiny wires who can play video games with his mind,” Musk told several thousand listeners in a Clubhouse chatroom. “You can’t see where the implant is and he’s a happy monkey. We have the nicest monkey facilities in the world. We want them to play mind-Pong with each other,” Musk added.
