General Information
Term lobula columnar neuron LC13 ID (Ontology) FBbt:00100485 (Fly Anatomy)
Definition Lobula columnar neuron whose cell body lies in the ventral area of the lateral cell body rind (Wu et al., 2016). It has a complex multilayer pattern, with arbors in lobula layers 2-6, with most synapses in layers 3, 5A and 5B (Wu et al., 2016; Tanaka and Clark, 2022). Presynaptic sites are observed in layers 3 and 4 (Wu et al., 2016). Its arbors span approximately 40 optic columns, overlapping with other LC13 cells (Wu et al., 2016). It projects to a large, very posterior optic glomerulus of the PVLP, posterior to LC11 (Wu et al., 2016). There are around 108 cells of this type (Wu et al., 2016).[ FlyBase:FBrf0193607 FlyBase:FBrf0233032 FlyBase:FBrf0234700 FlyBase:FBrf0253297 ]
Also Known As"LC13" ; "Lcn13"
CommentPre- versus postsynaptic innervation assessed with a presynaptic marker (synaptotagmin-HA driver) (Wu et al., 2016).
