General Information
Term lineage 2 secondary neuron ID (Ontology) FBbt:00048898 (Fly Anatomy)
Definition Any neuron that develops from neuroblast NB2-1 during the postembryonic phase of neurogenesis. These are all Notch ON hemilineage neurons, as the Notch OFF hemilineage is eliminated by apoptosis (Lacin et al., 2019). In the adult, these neurons are glutamatergic (Lacin et al., 2019).[ FlyBase:FBrf0231327 FlyBase:FBrf0242251 ]
Also Known As "hemilineage 2A larval-born neuron" ; "hemilineage 2A postembryonic neuron" ; "hemilineage 2A secondary neuron" (for all, see Synonyms field below)
