Pre- or post-synapse locations are the fewest regions that collectively contain at least 80 percent of all pre- or post-synapses of these (DNg66) neurons in FlyWire. fly_anatomy.ontology FBbt:00110330 DNad002 descending neuron of the gnathal ganglion DNg66 OA-VUMd4 Adult octopaminergic descending neuron of the VUMd cluster, with its soma posterior-ventral to the gnathal ganglion (Busch and Tanimoto, 2010; Schlegel et al., 2024; Dorkenwald et al., 2024). In the brain, it has postsynapses and presynapses in the saddle, the gnathal ganglion and the flange, and also has postsynapses in the cantle (Schlegel et al., 2024; Dorkenwald et al., 2024). In the VNC, it follows the median dorsal abdominal tract (Sturner et al., 2025). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024). There are approximately 1-2 of these cells per organism (Schlegel et al., 2024; Dorkenwald et al., 2024; Sturner et al., 2025).
