Australian Scientists Teach Brain Cells to Play Doom

Brain Cells Take on Doom in Groundbreaking Experiment

In a remarkable fusion of biology and technology, Australian researchers at Cortical Labs have trained lab-grown human brain cells to play the classic 1990s shooter game Doom. This experiment demonstrates how living neurons can process information, adapt to challenges, and learn tasks in real time.

How It Works

The team grew around 200,000 human brain cells from stem cells and placed them on a silicon chip called CL1. By converting the game’s digital environment into electrical signals, researchers stimulated the neurons to react when enemies appeared. Different patterns of neuron activity triggered specific actions, such as firing a weapon or moving through the game world.

Initially, the cells behaved like beginners—walking into walls, shooting randomly, and struggling to navigate. Over time, however, they began targeting enemies more accurately, proving that neurons can adapt and improve with training.

Beyond Gaming

While teaching brain cells to play Doom may sound like science fiction, the implications are profound:

• Healthcare: Neurons on chips could be used for drug screening, disease modeling, and personalized medicine.
• AI & Robotics: Biological computing offers real-time learning capabilities similar to artificial intelligence.
• Sustainability: The human brain runs on just 20 watts of power, far more efficient than current silicon chips.

Expert Insights

Cortical Labs’ chief scientist Brett Kagan described the CL1 chip as “a more sustainable and powerful form of intelligence.” Analysts agree the project could revolutionize computing by combining biological efficiency with machine learning.

Challenges Ahead

The cells currently have a six-month lifespan and cannot yet deliver consistent, programmable results. Still, researchers believe this is only the beginning of exploring biological intelligence systems.

Why It Matters

This experiment highlights the potential of merging biology with technology to create new forms of computing. From healthcare breakthroughs to sustainable AI, lab-grown neurons may one day power applications far beyond video games.
