DNp55 [FBbt_20011352]

Adult descending neuron with its soma in the posterior brain, dorsal to the superior posterior slope (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 ipsilateral anterior ventrolateral protocerebrum, and also has presynapses in the gnathal ganglion (Schlegel et al., 2024; Dorkenwald et al., 2024). Within the VNC, it fasciculates with the dorsal lateral tract of ventral cervical fasciculus and sends output to the leg neuropil and lower tectulum (Takemura et al., 2024; Marin 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., 2025).

Adult Cholinergic Nervous system primary neuron

Adult descending neuron with its soma in the posterior brain, dorsal to the superior posterior slope (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 ipsilateral anterior ventrolateral protocerebrum, and also has presynapses in the gnathal ganglion (Schlegel et al., 2024; Dorkenwald et al., 2024). Within the VNC, it fasciculates with the dorsal lateral tract of ventral cervical fasciculus and sends output to the leg neuropil and lower tectulum (Takemura et al., 2024; Marin 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., 2025).

Type identified at light level and matched across EM datasets by Sturner et al. (2025). Pre- or post-synapse locations are those with the highest total count of these neurons in FlyWire FAFB.
