General Information
Term neuroblast DALv2 ID (Ontology) FBbt:00050136 (Fly Anatomy)
Definition DAL neuroblast ventral to DALv1 (Hartenstein et al., 2015). It is found in the dorsal group of posterior protocerebral neuroblasts during the embryonic stage (Urbach et al., 2003; Kumar et al., 2009). Its primary neurons project to the larval lateral accessory lobe and mushroom body medial lobe (Hartenstein et al., 2015). Some primary neurons persist to the adult stage to target the fan-shaped body and noduli (Kandimalla et al., 2023). Each DALv2 neuroblast produces approximately 135 large-field central complex secondary neurons, the vast majority of which are ellipsoid body R-neurons (Omoto et al., 2018; Kandimalla et al., 2023).[ FlyBase:FBrf0161021 FlyBase:FBrf0194268 FlyBase:FBrf0208824 FlyBase:FBrf0221412 FlyBase:FBrf0221438 FlyBase:FBrf0229672 FlyBase:FBrf0240929 FlyBase:FBrf0257023 ]
Also Known As "neuroblast DALv2" ; "neuroblast EB" ; "neuroblast EBa1" (for all, see Synonyms field below)
Comment Bridi et al. (2019) - FlyBase:FBrf0243005 show that Ppd5 generates the EB ring neurons, making this synonymous with DALv2.
