General Information
Term descending neuron of the anterior ventral brain DNb07 ID (Ontology) FBbt:20011360 (Fly Anatomy)
Definition Adult descending neuron of the anterior ventral brain, with its soma ventral to the antennal lobe (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 ipsilateral superior and inferior posterior slope and the contralateral superior posterior slope, and presynapses in the gnathal ganglion (Schlegel et al., 2024; Dorkenwald et al., 2024). Within the VNC, it fasciculates with the median tract of dorsal cervical fasciculus I and sends output to the intermediate and upper tectulum (Takemura et al., 2024; Marin 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:FBrf0260535 FlyBase:FBrf0260546 ]
Also Known As "DNb07" ; "DNxn095"
Comment Type identified at light level and matched across EM datasets by Sturner et al. (2024). Pre- or post-synapse locations are those with the highest total count of these neurons in FlyWire FAFB.
