Measured MaleCNS v1.0 wiring constrains a spiking neural model with MuJoCo body physics and FlyVis vision. Behaviors include engineered scaffolds; they are model predictions, not measurements of a living fly. One fly is used to limit memory and processor demand. This advanced model requires a desktop browser with shared memory.
