General Information
Term lobula plate intrinsic neuron LPi3-4 ID (Ontology) FBbt:00111289 (Fly Anatomy)
Definition Lobula plate intrinsic neuron with its soma in the cell body rind of the medulla (Mauss et al., 2015; Shinomiya et al., 2019). The primary neurite traverses the medulla, from distal to proximal and crosses the second optic chiasm, to terminate in the lobula plate (Mauss et al., 2015; Shinomiya et al., 2019). It has presynaptic terminals in layer 4 and postsynaptic ones in layer 3 (Mauss et al., 2015; Shinomiya et al., 2019). It receives most of its input from T4c and T5c neurons (Shinomiya et al., 2022). It is a glutamatergic neuron (Mauss et al., 2015). There are around 55-60 of these cells on each side (Nern et al., 2025).[ FlyBase:FBrf0228988 FlyBase:FBrf0243899 FlyBase:FBrf0254308 FlyBase:FBrf0262545 ]
Also Known As"CB3857" ; "LPi09" ; "LPi3-4" (for all, see Synonyms field below)
CommentThe glutamate neurotransmitter was assessed by antibody staining and mRNA profiling (Mauss et al., 2015). Matsliah et al. (2024) - FBrf0260545 nomenclature scheme unrelated to layer innervation.
