General Information
Term descending neuron of the posterior brain DNp13 (male) ID (Ontology) FBbt:00049941 (Fly Anatomy)
Definition Doublesex-expressing adult descending neuron belonging to the DNp group in the male, having a cell body in the posterior medial protocerebrum, ventral to the pC1 cluster (Robinett et al., 2010; Wang et al., 2020). Compared to the female DNp13 cell, it has more periesophageal and subesophageal arborization, but less extensive arborization of higher regions (Wang et al., 2020). It extends along the full length of the ventral nerve cord, reaching the abdominal neuromere, but with less extensive arborization in this region than the female DNp13 cell (Wang et al., 2020). There is one of these cells per hemisphere (Robinett et al., 2010; Lillvis et al., 2024). It is activated by the presence of females, but not males (Takayanagi-Kiya and Kiya, 2019). It is cholinergic (Lillvis et al., 2024).[ FlyBase:FBrf0210735 FlyBase:FBrf0228365 FlyBase:FBrf0241873 FlyBase:FBrf0246914 FlyBase:FBrf0258823 ]
