General Information
Term descending neuron of the posterior brain DNp73 ID (Ontology) FBbt:20007547 (Fly Anatomy)
Definition Adult descending neuron with its soma in the brain, posterior-lateral to the inferior bridge (Schlegel et al., 2024; Dorkenwald et al., 2024). In the brain, it has postsynapses in the saddle, the ipsilateral antennal mechanosensory and motor center and the gnathal ganglion (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the contralateral inferior posterior slope, the gnathal ganglion and the saddle (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 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 "DNp73" ; "DNxn099"
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.
