General Information
Term NB7-4 lineage primary neuron ID (Ontology) FBbt:00048894 (Fly Anatomy)
Definition Any neuron that develops from neuroblast NB7-4 during the embryonic phase of neurogenesis. These all belong to the Notch OFF hemilineage, as Notch ON progeny develop as glial cells (Mark et al., 2021). Their axons project in anterior and posterior directions near the ventral midline (Mark et al., 2021).[ FlyBase:FBrf0231327 FlyBase:FBrf0249021 ]
Also Known As "hemilineage 23B embryonic neuron" ; "hemilineage 23B embryonic-born neuron" ; "hemilineage 23B primary neuron" (for all, see Synonyms field below)
