(2025). Soma location is based on the closest annotated neuropil region in FlyWire. fly_anatomy.ontology Adult anterior-projecting DN3 neuron with its soma lateral to the lateral horn (Sun et al., 2022; Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the SLPpl1 hemilineage (Dorkenwald et al., 2024; Schlegel et al., 2024). It remains ipsilateral, receiving input in the superior and posterior lateral protocerebrum, superior clamp and accessory medulla (Schlegel et al., 2024; Dorkenwald et al., 2024). Its main output regions are the superior lateral protocerebrum, superior clamp and anterior ventrolateral protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). There are approximately 2 of these cells per hemisphere (Nern et al., 2025). FBbt:20002643 VFB:FBbt_20002643 SLP249 SLP249
