Movement neuron spikes per leg, from six real 166,700-neuron fly connectomes running in your browser. The more a fly's walking circuits fire at the smell, the further it runs.

How a race works

Five legs. Each leg every fly smells the fruit; how strong the smell is changes lane to lane and leg to leg.
Real brains. Each fly is its own copy of the fruit-fly connectome with its own neural noise. Its walking neurons' spikes set how far it moves.
No steering. No game rule moves a fly; the finish order is whatever the brains did.
