General Information
Term lobula intrinsic neuron Li2 ID (Ontology) FBbt:00003884 (Fly Anatomy)
Definition Lobula intrinsic neuron with wide-field tangential arborization along lobula layers 1 and 2 (Fischbach and Dittrich, 1989; Nern et al., 2025). Its cell body is found in the optic lobe and its primary neurite follows the surface of the lobula, entering close to its region of arborization (Fischbach and Dittrich, 1989; Nern et al., 2025).[ FlyBase:FBrf0049410 FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ]
Also Known As "Li2" ; "lobula intrinsic neuron Li28" ; "lobular intrinsic neuron Li2"
Comment Li2 identified in FlyWire (Schlegel et al., 2024; Dorkenwald et al., 2024) and mapped to optic lobe dataset, where it is called Li28 (Nern et al., 2025). EM neuron morphology appears highly similar to that shown in Fischbach and Dittrich (1989), but more cells identified.
