Two copies of one measured nervous system: the complete CNS of an adult male Drosophila melanogaster (HHMI Janelia FlyEM, Cambridge Connectomics, Google Research, 2026, CC-BY). Each dot is a neuron at its measured soma position; it lights when it crossed threshold in the last 12 ms window.
Leaky integrate-and-fire after Shiu et al. 2024: rest −52 mV, threshold −45 mV, τ 20 ms, refractory 2.2 ms, 0.2 ms steps, 0.275 mV per synapse signed by transmitter. Nothing is trained. The male-specific pC1 and aIPg cells are what the lunge is read from.
Each fly sees the room through its own eye, sampled at the 892 retinotopic columns into L1/L2. The other male is a growing disc (looming). His pheromone reaches ORN_DA1 across the room, ppk23 on contact. Every hit is vibration into Johnston's organ. The food patch is a faint smell everywhere and a taste on it.
Six legs on the tripod gait, stride paced by the descending drive; wings rise into the male threat display when pC1/aIPg run hot and open on a lunge; the proboscis extends on food. Movement is read from DNa02, DNa01, MDN, DNp09 and the giant fiber against their own baselines.
A round is 10 minutes; the patch decides it. The loser's wallet pays the winner's 5% of its balance on Robinhood Chain, journaled before broadcast, hash in rounds. Creator fees land in red's wallet and are split with blue.
The trade-to-neuron mapping and the lunge/bolt thresholds are choices a person made and calibrated. No key is in the loop of the fight. Not living animals. Not an investment.
