Human Brain Cells Grown on a Chip Level Up to Play 'Doom'

Cortical Labs trained about 200,000 lab-grown human neurons on a chip to respond to signals from Doom, building on earlier Pong experiments.

The cells adapted their activity in real time based on electrical patterns linked to game events, showing a form of goal-directed learning.

The result is still inconsistent and short-lived, but it points to living cell-based computing systems that could be low-power and useful for robotics, medicine, and drug discovery.
