We let the monkeys play the “Pong” game



Neuralink, secret Neuroscience Startup Company The company co-founded by Elon Musk is now quieter than ever.That is, until this week’s release A youtube video A monkey appeared playing a classic video game pingpong Use its thoughts.

The narrator said that the video star Pager, a 9-year-old macaque, had nerve chains implanted on both sides of his brain about six weeks ago.Obviously, he likes pingpong.

However, before he learned how to play the game with his head, the researchers first asked him to use the joystick. Whenever he moved the cursor on the screen to some lighted square on the screen, he would use the ” “A delicious banana smoothie” rewarded him. A grid.

When he manipulated the joystick and happily sipped his smoothie, the Neuralink device in his brain recorded his brain activity, monitoring more than 2,000 electrodes implanted in the Pager motor cortex to control the movement of the hands and arms. Researchers can also pair with mobile phones via Bluetooth to interact with these devices in real time.

Then, the Neuralink data is input into the “decoder algorithm” to train it to predict Pager’s expected hand movements in real time based on the neurons being fired. After a short calibration time, the decoder has a good understanding of Pager’s neural model and no longer needs a joystick. The narrator said that even if the connection was disconnected, Pager still continued to move the cursor with his thoughts.Then he seems to be playing the so-called game MindPong No joystick can be seen.

“The monkey is actually using a brain chip to play video games telepathically!!” Musk said A tweet Share the video on Thursday.

Since then, more than 4 million people have watched the video, and it has become one of the top ten popular videos on YouTube.If you are interested, Neuralink also shared A video Shows what the raw data behind Pager’s neural activity looks like when he is busy with the game.

Musk continued to discuss the future plans of Neuralink equipment in China. Series of tweets, Echoing the video narration, the ultimate goal of this technology is to enable paralyzed people to operate their computers or phones through their brains.

Musk wrote that the initial version of the device “will enable paralyzed people to use smartphones faster than thumb users.” “Later versions will be able to transfer signals from the brain’s neural chain to the body’s motor/sensory neuron clusters. Nerve chain so that paraplegics can walk again.”

As early as August, Neuralink showed a live demonstration of the Neuralink implant, although On the pig Instead of monkeys.

“It’s like a Fitbit on a skull with tiny wires on it,” Musk said at the time.

Musk has a close relationshipCaused a series of science fiction-like uses Neuralink’s research Since its establishment in 2017, the company’s services have ranged from more practical examples, such as the treatment of brain diseases such as Parkinson’s disease, epilepsy and depression, as well as the aforementioned mobility aids for the paralyzed, to fantastic attempts, such as enhanced Our trivial human brain functions, so we can happily coexist with our ultimate AI overlord.

However, before all this happens, Neuralink needs to skip a series of regulatory challenges if it wants to get the opportunity to become a medical device approved for use in humans. In July, Musk announced that the U.S. Food and Drug Administration (FDA) designated Neuralink as “Breakthrough Device” It can quickly track the status of its federal review process. At least considering the government’s pace of glacialization of these things, at least it can be done. It may take years or even decades before any major progress is made in the law.

At the same time, maybe Neuralink can teach Pager to play more games with his own mind. I think that if the next one is not part of the Donkey Kong series, they will miss a huge opportunity. Even better: Ape escape.
