General Information
Term optic lobe visual centrifugal neuron OLVC4 ID (Ontology) FBbt:20001063 (Fly Anatomy)
Definition Adult visual centrifugal neuron with its soma posterior-medial to the posterior lateral protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). It belongs to the SMPp&v1 ventral hemilineage (Dorkenwald et al., 2024; Schlegel et al., 2024). In the contralateral optic lobe, it has both pre- and post-synapses in medulla layer M7 and in lobula layers 5 and 6 (Nern et al., 2025). In the central brain, it receives input in the ipsilateral protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). There is one of these cells per hemisphere (Nern et al., 2025).[ FlyBase:FBrf0246888 FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ]
Also Known As "adult clamp neuron 358" ; "centrifugal lobula and medulla-targeting neuron cLM01" ; "CL358" (for all, see Synonyms field below)
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.
