General Information
Term descending neuron of the posterior brain DNp15 ID (Ontology) FBbt:00047648 (Fly Anatomy)
Definition Descending neuron belonging to the DNp group, having a cell body on the posterior surface of the brain (Namiki et al., 2018). In the brain, it has dendrites in the inferior and superior posterior slope (Suver et al., 2016; Namiki et al., 2018). In the VNC, it fasciculates with the intermediate tract of the dorsal cervical fascicle and sends output to the neck and haltere neuropils (Suver et al., 2016; Namiki et al., 2018). It receives input from horizontal system neurons in the inferior posterior slope (Erginkaya et al., 2025). There is one of these cells per hemisphere and it remains ipsilateral (Suver et al., 2016; Namiki et al., 2018).[ FlyBase:FBrf0234044 FlyBase:FBrf0239335 FlyBase:FBrf0262578 ]
Also Known As "descending neuron of the horizontal system 1" ; "DNHS1" ; "DNp15" (for all, see Synonyms field below)
Comment Namiki et al. (2018), identify this as being morphologically similar to VGlut-F-800293 and Cha-F-700077, described by FlyCircuit (FBrf0212704).
