DNp59 DNlt008 fly_anatomy.ontology VFB:FBbt_20011332 Adult descending neuron with its soma in the posterior brain, dorsal 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 in the ipsilateral inferior clamp, superior medial protocerebrum, superior posterior slope and inferior bridge, and presynapses in the gnathal ganglion, the ipsilateral cantle and the saddle (Schlegel et al., 2024; Dorkenwald et al., 2024). Within the VNC, it fasciculates with the median dorsal abdominal tract and sends output to the lower tectulum (Takemura et al., 2024; Marin 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., 2025).
