General Information
Term descending neuron of the posterior brain DNp32 ID (Ontology) FBbt:00047665 (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 antennal lobe, antler, inferior clamp, superior clamp, crepine, flange, prow, saddle, superior lateral protocerebrum, posterior lateral protocerebrum, wedge, gorget, vest, gnathal ganglion, intermediate tectulum, T1 leg neuropil, T2 leg neuropil and T3 leg neuropil (Namiki et al., 2018). It fasciculates with the dorsal lateral tract of the ventral cervical fascicle and ventral medial tract of the ventral cervical fascicle in the ventral nerve cord (Namiki et al., 2018). There is one of these cells per hemisphere (Namiki et al., 2018) and it produces myosuppressin (McKim et al., 2024).[ FlyBase:FBrf0239335 ]
Also Known As "DMS descending neuron" ; "DNp32" ; "DNxl019" (for all, see Synonyms field below)
Comment Namiki et al. (2018), identify this as being morphologically similar to antennal lobe descending neuron 1, described by Tanaka et al. (2012) (FBrf0219809).
