General Information
Term NB1-2 lineage primary neuron ID (Ontology) FBbt:00048866 (Fly Anatomy)
Definition Any neuron that develops from neuroblast NB1-2 during the embryonic phase of neurogenesis. In the larva axons of some Notch ON progeny follow the ventral edge of the neuropil to reach the contralateral dorsal region, while Notch OFF progeny project anteriorly in the ventral neuropil (Mark et al., 2021).[ FlyBase:FBrf0231327 FlyBase:FBrf0249021 ]
Also Known As "lineage 1 embryonic neuron" ; "lineage 1 embryonic-born neuron" ; "lineage 1 primary neuron" (for all, see Synonyms field below)
