It is initially a small, homogenous, hemispherical domain containing the distal filopodia of afferent optic lobe interneurons and the proximal filopodia of DALcl1/2 dorsal hemilineages (Lovick et al., 2017). During metamorphosis, the different subcompartments of the adult AOTU become distinct (Lovick et al., 2017). larval AOTU
