General Information
Term adult superior lateral protocerebrum neuron 249 ID (Ontology) FBbt:20002643 (Fly Anatomy)
Definition 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).[ FlyBase:FBrf0246888 FlyBase:FBrf0253946 FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ]
Also Known As "SLP249"
Comment Cell type based on Hemibrain data (Scheffer et al., 2020), updated using FlyWire (FAFB) data (Dorkenwald et al., 2024; Schlegel et al., 2024) and identified at light level by Nern et al. (2025). Soma location is based on the closest annotated neuropil region in FlyWire.
