  "description": "BANC (\"Brain And Nerve Cord\") is a complete connectome of an adult FEMALE Drosophila melanogaster central\nnervous system \u2014 brain + ventral nerve cord in one specimen (~160,000 neurons, ~214M synapses) \u2014 imaged by\nGridTape transmission electron microscopy (Phelps & Kim, Wei-Chung Allen Lee lab, Harvard), segmented by\nZetta.ai, and proofread by the BANC-FlyWire community (Bates, Phelps, Kim, Yang et al. 2026).\n\nThis scene is the WHOLE connectome: 134,942 neurons across every neuronal super class with a published\nmesh \u2014 the optic-lobe intrinsic neurons, central-brain intrinsic neurons, ventral-nerve-cord intrinsic\nneurons, the descending/ascending bridge between brain and VNC, the sensory and motor periphery, and the\nvisual projection/centrifugal systems. Each neuron is a meshopt-q14-compressed 3D-Tiles surface tagged with\nthe BANC annotations: super class, region (central brain vs ventral nerve cord), cell type, side, predicted\nneurotransmitter, hemilineage, the sexual-dimorphism call, and cross-dataset cell-type matches (MaleCNS,\nMANC, hemibrain, FlyWire). Each neuron is colored individually; switch \"Color By\" to Super Class, Region,\nPredicted NT, or Dimorphism to read the organization. At ~135k neurons it is a dense whole-CNS volume \u2014\nuse the viewer's filter / Force-Zoom coarse LOD to explore regions and subsets.\n",
