General Information

Term

Td8 neuroblast

ID (Ontology)

FBbt:00005977 (Fly Anatomy)

Definition

Neuroblast 8 of the dorsal tritocerebrum. It displays serial homology to NB3-4 (Urbach et al., 2016). It delaminates in embryonic stage 11 (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.
