General Information
Term adult protocerebral bridge 1 glomerulus-ellipsoid body tile-nodulus 1 neuron ID (Ontology) FBbt:00003646 (Fly Anatomy)
Definition A small field neuron of the adult central complex with dendritic arbors in one protocerebral bridge (PB) glomerulus (excluding glomerulus 1), axonal terminals in an ellipsoid body tile, and axonal terminals in nodulus 1 in the opposite hemisphere to the PB innervation (Lin et al., 2013; Wolff et al., 2015). Its soma is close to the PB glomerulus it innervates (Wolff et al., 2015). It develops from one of the four central complex neuroblasts (Sullivan et al., 2019).[ FlyBase:FBrf0049409 FlyBase:FBrf0221742 FlyBase:FBrf0227801 FlyBase:FBrf0241592 ]
Also Known As "CX-SFN (pb-eb-no)" ; "P-EN neuron" ; "PB 1-glomerulus neuron>EBP-NoL1" (for all, see Synonyms field below)
