flydrive

Trains a hand-built Drosophila visual pathway to drive a car from 1728 ommatidia alone, then swaps in the whole MaleCNS graph (162,432 neurons, 24,380,527 edges) as the policy, learning only per-neuron dynamics and the input and output maps. Untrained T4 and T5 motion detectors reach direction-selectivity 0.98 and 0.89 straight from the wiring. At a matched 740k steps the frozen connectome drives crash-free where the hand-built pathway does not, but with six times the budget the hand-built model holds the lane at 0.70 m against 1.6 m, fine-tuning the brain hurt, and it costs 25x more per step.
