Human Brain Cells in Dish Learn to Play Pong Faster than AI

TEHRAN (Tasnim) – Hundreds of thousands of brain cells in a dish are being taught to play Pong by responding to pulses of electricity – and can improve their performance more quickly than an AI can.

Living brain cells in a dish can learn to play the video game Pong when they are placed in what researchers describe as a “virtual game world”. “We think it’s fair to call them cyborg brains,” says Brett Kagan, chief scientific officer of Cortical Labs, who leads the research.

As Australia-based Cortical Labs tells NewScientist, the neurons are being studied in Petri dishes to observe how networks form and interact with stimuli. The dishes themselves conduct electricity through the brain cell networks; these signals can then be used to change networks’ behaviors. They become living computer chips, in a way, InputMag reported.

As Brett Kagan, chief scientific officer of Cortical Labs explains, these neurons are more than just a dumping of brain cells on a dish. They’re a network capable of learning and completing tasks.

“We often refer to them as living in the Matrix,” Kagan says. “When they are in the game, they believe they are the paddle.”

Kagan and his team are able to educate the neuron network (which, by the way, they refer to as “DishBrain”) via electric stimulation. The electric signals tell the DishBrain where the ball is and, in just five minutes’ time, the DishBrain figures out how to move its “paddle” to hit the ball. The network of cells becomes the paddle.

Not to disparage anyone’s experiments here, but AI is looking like small fries in comparison to DishBrain right about now. Pong is an easy game to learn, but five minutes’ learning time is really impressive. Sure, AI can drive delivery trucks around with no problem — but imagine how much more quickly DishBrain might be able to learn the same task, given the right inputs.

DishBrain is just a lab experiment right now, but the team at Cortical Labs sees this success as a step toward creating fully synthetic brains. Those brains would theoretically be able to outsmart even the best AI on the market. Which is both thrilling and highly concerning, seeing as AI is already wicked smart. A full-fledged DishBrain might just take over the world.
