General Information
Term lobula columnar neuron LC16 ID (Ontology) FBbt:00111751 (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 its main dendritic arbors in lobula layers 3-5B, with most synapses in layer 5B (Wu et al., 2016; Tanaka and Clark, 2022). Presynaptic sites are observed in layers 4 and 5B (Wu et al., 2016). Its arbors span approximately 30 optic columns, overlapping with other LC16 cells (Wu et al., 2016). It projects to a dorsal optic glomerulus of the PVLP (Wu et al., 2016). There are around 96 cells of this type (Wu et al., 2016). They are cholinergic (Davis et al., 2020).[ FlyBase:FBrf0233032 FlyBase:FBrf0234700 FlyBase:FBrf0244935 FlyBase:FBrf0253297 ]
Also Known As "LC16"
Comment Pre- versus postsynaptic innervation assessed with a presynaptic marker (synaptotagmin-HA driver) (Wu et al., 2016).
