General Information

Term

Dv6 neuroblast

ID (Ontology)

FBbt:00005965 (Fly Anatomy)

Definition

Neuroblast 6 of the ventral deutocerebrum. It displays serial homology to NB3-2 and NB4-2 (Urbach et al., 2016). It delaminates in early embryonic stage 9 (Urbach et al., 2016).[ FlyBase:FBrf0161021 FlyBase:FBrf0232096 ]

Comment

Numbering also indicates relative position: we follow the nomenclature of Urbach et al. (2003), in which neuroblasts are numbered from anterior-to-posterior and ventral-to-dorsal (so that numbers reflect relative positions along the dorsoventral axis). Figure 1 of Urbach et al., 2003, provides a survey of the spatial organization of the embryonic head and brain neuroblasts of a stage 11 embryo.
