has synaptic IO in region adult ellipsoid body ring neuron VFB:FBbt_00003649 Large field neuron that forms ring-shaped arborizations in the ellipsoid body that circle the ellipsoid body canal (Hanesch et al., 1989). These arborizations may form complete or partial rings (Hanesch et al., 1989). There are two main subtypes, which can be distinguished by their extent of arborization outside of the ellipsoid body and their developmental origin (Hanesch et al., 1989; Omoto et al., 2018). fly_anatomy.ontology TL neuron FBbt:00003649 ellipsoid body large field neuron of the central complex
