It is a putative embryonic-born neuron (Schlegel et al., 2024; Dorkenwald et al., 2024). In the brain, it has postsynapses in the ipsilateral anterior and posterior ventrolateral protocerebrum and inferior clamp, and presynapses in the saddle, the gnathal ganglion, the ipsilateral anterior and posterior ventrolateral protocerebrum and the contralateral cantle (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 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). VFB:FBbt_20011331 DNp103 DNp103 DNlt007 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. FBbt:20011331 bilateral
