General Information
Term lineage 15 secondary neuron ID (Ontology) FBbt:00048900 (Fly Anatomy)
Definition Any neuron that develops from neuroblast NB2-3 during the postembryonic phase of neurogenesis. These are all Notch OFF hemilineage neurons, as the Notch ON hemilineage is eliminated by apoptosis (Lacin et al., 2019). In the adult, these are all glutamatergic motor neurons (Lacin et al., 2019).[ FlyBase:FBrf0231327 FlyBase:FBrf0242251 ]
Also Known As "hemilineage 15B larval-born neuron" ; "hemilineage 15B postembryonic neuron" ; "hemilineage 15B secondary neuron" (for all, see Synonyms field below)
