General Information
Term descending neuron of the gnathal ganglion DNg42 ID (Ontology) FBbt:20007486 (Fly Anatomy)
Definition Adult descending neuron with its soma in the gnathal ganglion, ventral to the prow (Schlegel et al., 2024; Dorkenwald et al., 2024). In the brain, it has postsynapses in the gnathal ganglion and the ipsilateral inferior posterior slope, and presynapses in the gnathal ganglion (Schlegel et al., 2024; Dorkenwald et al., 2024). In the VNC, it follows the median tract of dorsal cervical fasciculus I (Sturner et al., 2024). Its predicted neurotransmitter is glutamate (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 "DNg42" ; "DNxn052"
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.
