General Information
Term descending neuron of the gnathal ganglion DNg50 ID (Ontology) FBbt:20007494 (Fly Anatomy)
Definition Adult descending neuron with its soma in the gnathal ganglion, ventral to the inferior posterior slope (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 in the gnathal ganglion, the saddle and the ipsilateral superior posterior slope, and presynapses in the gnathal ganglion (Schlegel et al., 2024; Dorkenwald et al., 2024). In the VNC, it follows the dorsal lateral tract of dorsal cervical fasciculus (Sturner et al., 2024). 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:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260546 ]
Also Known As "DNg50" ; "DNxn054"
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.
