General Information
Term descending neuron of the posterior brain DNp33 ID (Ontology) FBbt:00047666 (Fly Anatomy)
Definition Descending neuron belonging to the DNp group, having a cell body posterior to the inferior clamp (Matsuo et al., 2016; Namiki et al., 2018). In the brain it extends to the posterior side of the ipsilateral antennal mechanosensory and motor center zone D, branching to form postsynaptic terminals in zones B, C, D and E (Matsuo et al., 2014). It then passes through the posterior side of the gnathal ganglion (Matsuo et al., 2014) and descends on the ipsilateral side of the cervical connective (Namiki et al., 2018). In the VNC, it remains ipsilateral, fasciculating with the ventral lateral tract of the ventral cervical fascicle and innervating the neck, wing and haltere neuropils and the intermediate tectulum (Namiki et al., 2018). There is one of these cells per hemisphere (Namiki et al., 2018; Sturner et al., 2025).[ FlyBase:FBrf0225118 FlyBase:FBrf0230862 FlyBase:FBrf0239335 FlyBase:FBrf0262850 ]
Also Known As"AMMC-D1 neuron" ; "AMMC-D1 PN" ; "antennal mechanosensory and motor center D1 projection neuron" (for all, see Synonyms field below)
