Living brain organoids teach robots and play games
Human brain organoids now guide robots, play Doom, and compute—blurring life and AI
Human brain organoids—lab-grown clusters of a few million neurons—are emerging as a radical alternative to artificial intelligence. At the University of California San Diego (UCSD), neuroscientists led by Alysson Muotri have coaxed these organoids to interface with robots, navigating maze environments using live neural activity. In Melbourne, a startup claims its organoids can play video games like Pong and Doom, while at Johns Hopkins, researchers are developing biocomputing systems powered by living neurons.
These organoids start as adult skin or blood cells reprogrammed into pluripotent stem cells, then cultured in petri dishes where they self-assemble into neural networks. Within months, they generate electrical oscillations similar to fetal brainwaves. Muotri’s lab has pushed boundaries further—reviving Neanderthal-like genetic variants in organoids and even sending them to the International Space Station to study cosmic radiation effects on neural development. With applications in autism research (including organoids grown from his autistic son’s cells) and drug testing, this work suggests that future intelligence may not be artificial at all—but alive.
