General Information
Term ellipsoid body inner central domain ID (Ontology) FBbt:00007553 (Fly Anatomy)
Definition Concentric subdivision of the ellipsoid body that lies anteriorly in the inner part of the ellipsoid body (Renn et al., 1999; Lin et al., 2013; Omoto et al., 2018). It contains the arborizations of R3a, R3d and R3m ring neurons (Omoto et al., 2018).[ FlyBase:FBrf0111476 FlyBase:FBrf0221742 FlyBase:FBrf0240929 ]
Also Known As"EBic"
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) included R2 neuron arborizations in this (EBA) domain, but Renn et al. (1999) and Omoto et al. (2018) assign them to the outer domain (EBoc).
