General Information
Term adult doublesex aDN neuron ID (Ontology) FBbt:00047354 (Fly Anatomy)
Definition Doublesex-expressing neuron of the adult that has its soma in the anterodorsal region of the superior protocerebrum (Lee et al., 2002). There are two of these cells per hemisphere in both males and females (Nojima et al., 2021). In both sexes, their neurites are all ipsilateral, with a medial arbor in the superior medial protocerebrum containing mainly presynaptic sites (Nojima et al., 2021). Lateral arborization, containing mainly postsynaptic sites, is sexually-dimorphic (Nojima et al., 2021). These neurons are glutamatergic (Pavlou et al., 2016).[ FlyBase:FBrf0159058 FlyBase:FBrf0210397 FlyBase:FBrf0210735 FlyBase:FBrf0234085 FlyBase:FBrf0248430 ]
Also Known As "doublesex-expressing anterior-Dorsal Neuron" ; "dsx-aDN" ; "dsx-expressing anterior-Dorsal Neuron"
Comment Lee et al. (2002) and Robinett et al. (2010) state that they do not see aDN in the female, but Rideout et al., 2010 and Pavlou et al., 2016 show that they are present in the female. These neurons do not express fruitless (Pavlou et al., 2016).
