200,000 human neurons learn to play Doom: breakthrough or hype?

A handful of human neurons in a Petri dish has learned to navigate the hellish corridors of Doom. The Australian startup Cortical Labs got 200,000 brain cells, grown on its CL1 chip, to take control of Doomguy in late February 2026. The video went viral, but skepticism was quick to trinc.

The experiment, documented by outlets such as SomosKudasai and Infobae, shows how these neurons respond to the game's stimuli in real time, learning to shoot and dodge enemies over several days. However, 200,000 neurons are a far cry from the 86 billion in an adult human brain. It's enough to process basic signals, but hardly enough for what we would call "playing".

  • The CL1 system integrates living neurons into hardware that keeps them active and fed with feedback.
  • The neurons are obtained from adult donors and grown on a chip.
  • The video shows the "mini-brain" making decisions in the game, albeit with slow responses.

The reaction from the scientific and tech community has been a mix of fascination and skepticism. Some see it as an advance in biological computing; others see it as a marketing stunt to attract investment. Some also recall the "Head in a Jar" card from the 1994 game Illuminati, in which a brain in a jar governed a state. The irony is that science sometimes turns memes into reality.


Is this the first step towards functional biological computers, or simply a clever demo with no real applications? The video is out there, but the question remains open.
