Neuralink, Elon Musk’s company focused on developing brain-machine interfaces, has posted a video to YouTube that appears to show a monkey navigating an on-screen cursor using only its mind.
Pager, a 9-year-old macaque monkey, had a Neuralink implanted about six weeks before the video was shot, the video’s unnamed narrator says. He was first taught to play video games with a joystick for a banana smoothie reward, delivered through a metal straw. While he was doing this, the Neuralink device recorded information about which neurons were firing — learning, essentially, to predict hand movements by recording which regions fired. After learning the patterns, the joystick Pager used to play was disconnected from the computer. The monkey appears to go on playing the game using only his mind — playing a game of Pong with no joystick whatsoever.
First @Neuralink product will enable someone with paralysis to use a smartphone with their mind faster than someone using thumbs
