800,000 Human Brain Cells in a Petri Dish Just Learned to Play DOOM
A petri dish of 800,000 living human neurons just learned to play DOOM โ not with AI, but with actual biological brain cells firing through 59 electrodes, making real-time gameplay decisions.
From Lab Bench to Laptop
Cortical Labs, the Melbourne-based startup behind the 2022 DishBrain Pong experiment, has taken a massive leap. Using their newly released CL API, a developer got living neural cultures to play the iconic 1993 shooter. The neurons receive game state data as electrical stimulation and respond with movement commands in a real-time closed-loop.
The bigger news: on March 10, founder Hon Weng Chong announced the Cortical Cloud โ the world's first Biological Data Centre with 120 internet-connected CL1 units. Through a Python API, anyone can now remotely stimulate biological neural networks, read their responses, and build on living tissue. A 1,000-unit facility in Singapore is already planned with partner DayOne.
Why It Matters
Cortical Labs calls this Organic Intelligence (OI) โ computation by real biology, not silicon simulations. The practical applications extend well beyond gaming: real-time drug screening on living neurons, neurological disorder research, and energy-efficient computing (biological neurons use orders of magnitude less power than GPUs).
The CL API's technical foundation is detailed in a February 2026 arXiv paper, offering sub-millisecond timing, multi-channel synchronization, and a declarative Python interface โ no hardware expertise needed.
