Body: NeuroMechFly, a model, not the fly the nervous system came from; the nervous system is placed in it by hand: brain and cord where they sit in the animal, and the neck connective bent between them, since the dissected BANC does not keep its shape there. Outline: the BANC tissue surface. Walking: one recorded stride per leg from NeuroMechFly's step data, replayed on the model. Data: Bates, Phelps, Kim, Yang et al., Distributed control circuits across a brain-and-cord connectome, Nature (2026). BANC v888 public meshes, skeletons and region outlines, gs://lee-lab_brain-and-nerve-cord-fly-connectome. NeuroMechFly is NeLy-EPFL, Apache-2.0. Interface: scifi-ui. Codex is built at the Princeton Neuroscience Institute.
