General Information
Term descending neuron of the gnathal ganglion DNg61 ID (Ontology) FBbt:20007672 (Fly Anatomy)
Definition Adult descending neuron with its soma in the ventral gnathal ganglion, ventral to the wedge (Sterne et al., 2021; Schlegel et al., 2024; Dorkenwald et al., 2024). It is a putative embryonic-born neuron (Schlegel et al., 2024; Dorkenwald et al., 2024). In the brain, it has postsynapses and presynapses in the gnathal ganglion (Sterne et al., 2021; Schlegel et al., 2024; Dorkenwald et al., 2024). This arborization is mainly ipsilateral, but close to the midline, and it descends on the ipsilateral side (Sterne et al., 2021). In the VNC, it follows the dorsal lateral tract of dorsal cervical fasciculus (Sturner et al., 2025) and has axonal arborization in the T1 leg neuropil (Sterne et al., 2021). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024). There are approximately 2 of these cells per organism (Schlegel et al., 2024; Dorkenwald et al., 2024; Sturner et al., 2025).[ FlyBase:FBrf0251280 FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262850 ]
Also Known As "adult sink subesophageal neuron" ; "DNfl007" ; "DNg61"
Comment Type identified at light level and matched across EM datasets by Sturner et al. (2025). Pre- or post-synapse locations are the fewest regions that collectively contain at least 80 percent of all pre- or post-synapses of these neurons in FlyWire.
