Term descending neuron of the posterior brain DNp17 ID (Ontology) FBbt:00047650 (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). This neuron does not cross the midline and descends on the ipsilateral side of the cervical connective (Namiki et al., 2018). It has neurites in the posterior lateral protocerebrum, inferior posterior slope, gnathal ganglion and haltere neuropil (Namiki et al., 2018). It fasciculates with the intermediate tract of the dorsal cervical fascicle in the ventral nerve cord (Namiki et al., 2018). There are around six of these cells in each hemisphere (Namiki et al., 2018, Berg et al., 2025, Bates et al., 2025).[ FlyBase:FBrf0239335 ]
Also Known As"DNp17"
Comment4 per hemisphere in Namiki et al. (2018), 6 per hemisphere in male-cns v0.9 (Berg et al., 2025), 8 per hemisphere in BANC v626 (Bates et al., 2025).
