Elon Musk’s NeuraLink recently released a video of Pager, a nine-year-old Macaque, playing Pong with his mind. The video reveals how much progress NeuraLink has made since last year’s livestream event.
Pager had a NeuraLink implanted into his brain six weeks ago. He was taught to play games with a joystick. Pager was well compensated for his gameplay with banana smoothies.
Pager’s brain activity was monitored through the NeuraLink app connected to the implant in his brain via Bluetooth. The data collected from the implant was recorded and ran through a decoder algorithm, which was then used to predict neural activity patterns correlated to Pager’s joystick movements.

In other words, the decoder was used to see which parts of Pager’s brain was active when he made specific movements with the joystick to control the mouse. After calibration, output from the decoder was used to move the cursor in the game instead of the joystick.
