General Information
Term descending neuron of the gnathal ganglion DNg77 ID (Ontology) FBbt:20007677 (Fly Anatomy)
Definition Adult descending neuron with its soma in the gnathal ganglion, ventral to the antennal mechanosensory and motor center (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 (Schlegel et al., 2024; Dorkenwald et al., 2024). This arborization is bilateral, but mainly in the ipsilateral hemisphere, and it descends on the contralateral side (Sterne et al., 2021). In the VNC, it follows the median dorsal abdominal tract (Sturner et al., 2024) and has axonal arborization in the neck 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., 2024)." [FlyBase:FBrf0251280, FlyBase:FBrf0259490, FlyBase:FBrf0260535, FlyBase:FBrf0260546] {comment="doi:10.1101/2024.06.04.596633"}
Also Known As "adult snake subesophageal neuron" ; "DNg77" ; "DNit002"
Comment Type identified at light level and matched across EM datasets by Sturner et al. (2024). 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.
