General Information
Term ellipsoid body outer central domain ID (Ontology) FBbt:00007556 (Fly Anatomy)
Definition Outer concentric subdivision of the ellipsoid body. It contains the arborization of R2, R4d and R4m ring neurons (Renn et al., 1999; Young and Armstrong, 2010; Omoto et al., 2018).[ FlyBase:FBrf0111476 FlyBase:FBrf0221742 FlyBase:FBrf0240929 ]
Also Known As"EBoc"
CommentThe 'anterior ring' of Hanesch et al. (1989) and 'anterior disk' of Renn et al. (1999) appear to refer to EBa, EBic and EBoc, collectively. The 'medial shell' of Wolff et al. (2015) refers to EBic and EBoc (Omoto et al., 2018). Lin et al. (2013) do not seem to include R2 neurons in the outer ring (EBO), but they are included by Renn et al. (1999) and by Omoto et al. (2018), who claim that EBO corresponds to EBoc.
