General Information
Term lineage 20 secondary neuron ID (Ontology) FBbt:00048915 (Fly Anatomy)
Definition Any neuron that develops from neuroblast NB5-7 during the postembryonic phase of neurogenesis. A much larger number of the A hemilineage neurons survive, compared to the B hemilineage (Lacin et al., 2019). Neurons of each hemilineage signal via different neurotransmitters (Lacin et al., 2019).[ FlyBase:FBrf0231327 FlyBase:FBrf0242251 ]
Also Known As "lineage 20 larval-born neuron" ; "lineage 20 postembryonic neuron" ; "lineage 20 secondary neuron" (for all, see Synonyms field below)
Comment Lacin et al. (2019) cite Lacin and Truman (2016) to say that NBs 5-4 and 5-7 make lineages 20 and 22, respectively, but this is the wrong way round according to the latter.
