General Information
Term adult doublesex pC2 neuron ID (Ontology) FBbt:00053231 (Fly Anatomy)
Definition Doublesex neuron that is part of a cluster in the posterior region of the protocerebrum. There are around 26 of these cells per hemisphere in the female and around 67 in the male (Kimura et al., 2015). Some arise from the CP3 (DL2) neuroblast (Ren et al., 2016).[ FlyBase:FBrf0159058 FlyBase:FBrf0210397 FlyBase:FBrf0210735 FlyBase:FBrf0225543 FlyBase:FBrf0228365 FlyBase:FBrf0233706 FlyBase:FBrf0234085 FlyBase:FBrf0245074 ]
Also Known As "doublesex-expressing posterior Cell-2" ; "dsx-expressing posterior Cell-2" ; "dsx-pC2"
Comment Kimura et al. (2015) report around 27 pC1 (female) cells per hemisphere, Zhou et al. (2014) and Pavlou et al. (2016) report around 8, Ren et al. (2016) and Wang et al. (2020) report 5. Unlike in the male, there does not appear to be overlap between dsx pC1 and fru pMP-e in the female (Ren et al., 2016).
