Y6 FBbt:00007580 FlyBrain_NDB:10182 VFB:FBbt_00007580 Y neuron that arborizes relatively broadly in all lobula plate layers and with a mix of terminal morphologies. Its branch in the lobula has narrow and mainly bleb-type arborizations in layers 1-4. Its branch in the lamina has a broader, bushy, fine, terminal arborization domain in layers M8-9. fly_anatomy.ontology Y6
