Scientists taught a petri dish of brain cells to play pong faster than an AI

As a lover of tough single player games, I’m quite accustomed to getting my butt handed to me by AI, and usually not even a real one. I also happen to be the owner of a full sized human brain. Though it’s not without its problems, the human brain’s ability to learn and change is usually why I eventually overcome those difficult in-game challenges.
So when I read about a few human brain cells in a petri dish that are already performing much better at a videogame than AI can, it’s concerning to me and my gaming future.New Scientistreports that a team in Australia has been growing these small puddles of brain and now one has learnt to play Pong, in fairly impressive time.
Cortical labsis a company working on integrating biological neurons with your more traditional silicon based computing hardware. They grow brain cells on microelectronic arrays, so the cells can be stimulated. These hybrid chips are said to be able to learn and restructure themselves to get past problems, like stopping a sneaky ball that wants in your goal.
According to Cortical labs, AIs typically take 90 minutes to learn Pong, whereas this ‘DishBrain’ (yes, that’s what it’s called) managed to have it down in five. Though the researchers do note that a good AI would still absolutely demolish the cells, once both properly trained.

The team managed this by using electrical signals to communicate where the ball is in-game to the DishBrain. The neurons could then move the paddles to collide with the ball, which is pretty insane stuff. Though, I’m fairly sure I worked out Pong faster, and without a full team of scientists helping, just saying.
Chief scientific officer of Cortical Labs, Brett Kagan told New Scientist “We think it’s fair to call them cyborg brains,” and went on to explain that when the brains are moving the paddles in Pong, they’re convinced that they’re the paddles.
“We often refer to them as living in the Matrix,” he explains. “When they are in the game, they believe they are the paddle.”

Hope’s been writing about games for about a decade, starting out way back when on the Australian Nintendo fan site Vooks.net. Since then, she’s talked far too much about games and tech for publications such as Techlife, Byteside, IGN, and GameSpot. Of course there’s also here at PC Gamer, where she gets to indulge her inner hardware nerd with news and reviews. You can usually find Hope fawning over some art, tech, or likely a wonderful combination of them both and where relevant she’ll share them with you here. When she’s not writing about the amazing creations of others, she’s working on what she hopes will one day be her own.
