General Information
Term ellipsoid body outer posterior domain ID (Ontology) FBbt:00007554 (Fly Anatomy)
Definition Concentric subdivision of the ellipsoid body that lies posteriorly, distal to the canal (Omoto et al., 2018). It contains the arborization of R6 ring neurons (Omoto et al., 2018).[ FlyBase:FBrf0111476 FlyBase:FBrf0221742 FlyBase:FBrf0240929 ]
Also Known As"EBop"
CommentThe 'posterior ring' of Hanesch et al. (1989) and 'posterior disk' of Renn et al. (1999) appear to refer to EBop and EBip collectively. The 'posterior shell' of Wolff et al. (2015) also refers to EBop and EBip collectively (Omoto et al., 2018). This region was defined (as EBP) by Lin et al. (2013), but no R ring neurons known at the time arborized here.
