General Information
Term lobula columnar neuron LC17 ID (Ontology) FBbt:00111752 (Fly Anatomy)
Definition Lobula columnar neuron whose cell body lies in the anterior area of the lateral cell body rind (Wu et al., 2016). It has its denser dendritic arbors in the boundary between lobula layers 2/3, where most of its synapses are found, and some diffuse branches near 3/4 and 5B (Wu et al., 2016; Tanaka and Clark, 2022). Its arbors span approximately 30 optic columns, overlapping with other LC17 cells (Wu et al., 2016). It projects to the most lateral of the ventral optic glomeruli of the PVLP (Wu et al., 2016). There are around 181 cells of this type (Wu et al., 2016).[ FlyBase:FBrf0233032 FlyBase:FBrf0234700 FlyBase:FBrf0253297 ]
Also Known As "LC17"
Comment Pre- versus postsynaptic innervation assessed with a presynaptic marker (synaptotagmin-HA driver) (Wu et al., 2016).
