A fruit-fly connectome takes a turn at Pong
Credibility concern recorded. The source reference remains available for verification and correction.
Fly Chip presents an in-browser simulation of a fruit-fly brain, while a CPU learns to move a Pong paddle from the brain’s output.

- Worth noticing
- The page says the 9 MB compressed connectome is stepped about 1,000 times per brain-second; slow phones run below real time.
Field notes
The page describes a browser-side model built from the BANC connectome: 158,262 neurons and 3.1 million synapses, with sensory populations and dopamine cells selected for stimulation. It says the compressed wiring file is 9 MB and the simulation advances about 1,000 times per brain-second, though slower phones fall behind. Its caveats separate mapped connections from a simplified leaky integrate-and-fire model and a custom reward rule; the extracted view still reads “waking up.”
