General Information
Term descending neuron of the posterior brain DNp65 ID (Ontology) FBbt:20007551 (Fly Anatomy)
Definition Adult descending neuron with its soma in the brain, posterior to the antler (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 prow and the ipsilateral flange, and also has presynapses in the contralateral flange (Schlegel et al., 2024; Dorkenwald et al., 2024). In the VNC, it follows the median dorsal abdominal tract (Sturner et al., 2024). Its predicted neurotransmitter is GABA (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 "DNp65" ; "DNxn092"
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.
