It has both fine and bleb-type arborizations in medulla layer M10, but displays only fine arborizations in medulla layers M3, M5, M6, the serpentine layer, M8 and M9 (Morante and Desplan, 2008; Fischbach and Dittrich, 1989). It is a cholinergic neuron (Varija Raghu et al., 2011). The neurotransmitter was assessed by co-labelling cells with a Cha-GAL4.7.4 driver (FBtp0014830) and an anti-ChAT antibody (Varija Raghu et al., 2011). Pre- versus postsynaptic innervation judged by scoring of terminal morphology from figures in Fischbach and Dittrich (1989) as assessed by FlyBrain Neuron DB.
