ID: FBbt_00047626

Adult fruitless-expressing octopaminergic descending neuron of the DNg group, having a cell body near the midline of the anterior gnathal ganglion (Yu et al., 2010; Certel et al., 2010; Namiki et al., 2018), in the mandibular segment (Busch and Tanimoto, 2010). It forms bilaterally symmetric arbors in the ventromedial neuropils and the subesophageal zone (Busch et al., 2009; Namiki et al., 2018). It descends on the ipsilateral side of the cervical connective and fasciculates with the ventral lateral tract of the ventral cervical fascicle (Namiki et al., 2018). In the VNC, it innervates the T1, T2 and T3 leg neuropils and the abdominal neuromere, ipsilaterally (Busch et al., 2009; Namiki et al., 2018). There is one of these cells per hemisphere (Namiki et al., 2018). It is glutamatergic as well as octopaminergic (Cheong et al., 2024).

Namiki et al. (2018), identified this as being morphologically similar to the octopaminergic VPM1 neuron (FBbt:00110149), described by Busch et al. (2009) (FBrf0207458) and the fruitless aDT8 neuron (FBbt:00110543), described by Yu et al. (2010) (FBrf0211884) - confirmed by Sturner et al. (2025) - FlyBase:FBrf0262850.
