(2025). Pre- or post-synapse locations are those with the highest total count of these neurons in FlyWire FAFB. Full name for BDN2 from codex (2025-03-04). VFB:FBbt_20007473 fly_anatomy.ontology DNxl058 adult major bolt protocerebral neuron output descending neuron 2 Adult descending neuron with its soma in the gnathal ganglion, ventral to the antennal mechanosensory and motor center (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 gnathal ganglion, the saddle and the contralateral vest (Schlegel et al., 2024; Dorkenwald et al., 2024). It has presynapses in the gnathal ganglion, and the contralateral wedge, vest and inferior posterior slope (Schlegel et al., 2024; Dorkenwald et al., 2024). In the VNC, it follows the dorsal lateral tract of dorsal cervical fasciculus (Sturner et al., 2025). 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., 2025). DNg100 bilateral
