General Information
Term NB4-1 lineage primary neuron ID (Ontology) FBbt:00048877 (Fly Anatomy)
Definition Any neuron that develops from neuroblast NB4-1 during the embryonic phase of neurogenesis. The Notch ON hemilineage projects to the dorsal neuropil of both hemispheres and the Notch OFF hemilineage projects to the ventral neuropil of both hemispheres (Mark et al., 2021).[ FlyBase:FBrf0231327 FlyBase:FBrf0249021 ]
Also Known As "lineage 14 embryonic neuron" ; "lineage 14 embryonic-born neuron" ; "lineage 14 primary neuron" (for all, see Synonyms field below)
