Elon Musk’s company Neuralink has published a video in which a monkey plays video games without touching the joystick.
The animal plays on the computer using the power of thought thanks to the implanted N1 Link implant with 1024 electrodes.
In the video, a 9-year-old macaque named Paige moves objects on the monitor with a cursor. She had neural chips implanted in her brain about six weeks before the shooting.
After that, Page was trained to play with a joystick for food. In parallel, the Neuralink system collected information about the functioning of neurons in the animal’s brain and learned to transmit information about hand movements.
The collected neural data records were then put into a decoding algorithm. He, in turn, mathematically modeled the relationship between the patterns (often repetitive sequences) of neural activity and the joystick movements that this activity produced.
As a result, according to the company, based on the data from the chips, the algorithm learned to predict the actions of the monkey literally in real-time.
After that, the company turned off the joystick. As you can see in the video, the monkey, out of habit, still uses it to play, although the wire is disconnected. Page is now in full control of the cursor with decoded neural activity.
