Human brain cells learn to play Doom in a biological computing experiment

Living human brain cells have been trained to play the classic video game Doom. This marks a significant advancement in biological computing. Researchers used a device housing human neurons connected to software that translates gameplay into electrical signals and neural activity into game controls. The neurons learned through rewards for successful actions. Doom has long been an unofficial benchmark for new systems, previously ported to diverse platforms. This experiment demonstrates neural adaptability and learning outside the brain.
