A newly mapped fly brain is playing Doom within days

Claim

Google and Janelia mapped the male fruit fly's 166,000 neurons, and within days it was playing Doom badly, flinching in a consumer gadget, solving a Rubik's cube and trading bitcoin — a decade of mapping becoming a weekend of agents.

Reported metric: 166,000 neurons

Reporting date: 2026-09-12 (not necessarily the event date)
