Pre- versus postsynaptic innervation judged by scoring of terminal morphology from figures in Fischbach and Dittrich (1989) as assessed by FlyBrain Neuron DB. Transmedullary Y neuron that terminates with bleb-type arborizations in lobula layers 5 and 6, and in lobula plate layer 1. It displays both fine and bleb-type arborizations in medulla layers M3, M6 and M8, but has only fine arborizations in medulla layer M4 and the serpentine layer. It is a cholinergic neuron (Varija Raghu et al., 2011).
