General Information
Term NB4-2 lineage primary neuron ID (Ontology) FBbt:00048878 (Fly Anatomy)
Definition Any neuron that develops from neuroblast NB4-2 during the embryonic phase of neurogenesis. Primary neurons of the thoracic B (Notch OFF) hemilineage include commissural interneurons in the larva, having ipsilateral input and contralateral output, and these become local leg interneurons during metamorphosis (Truman et al., 2023).[ FlyBase:FBrf0231327 FlyBase:FBrf0255928 ]
Also Known As "lineage 13 embryonic neuron" ; "lineage 13 embryonic-born neuron" ; "lineage 13 primary neuron" (for all, see Synonyms field below)
