It has its main dendritic arbors in lobula layers 4 and 5B (Wu et al., 2016), with most synapses concentrated in layer 5B (Tanaka and Clark, 2022). There is also some evidence of presynaptic sites in layers 4 and 5B (Wu et al., 2016). Its arbors span approximately 30 optic columns, overlapping with other LC6 cells (Wu et al., 2016). It fasciculates in the anterior optic tract, fasciculating with LC9 (Otsuna and Ito, 2006), and innervates an optic glomerulus in the dorsolateral PVLP, ventral to the one from LC16 (Wu et al., 2016; Morimoto et al., 2020). There are around 60 of these cells per hemisphere and they are cholinergic (Morimoto et al., 2020).
