Pre- versus postsynaptic innervation judged by scoring of terminal morphology from figures in Fischbach and Dittrich (1989) as assessed by FlyBrain Neuron DB. Tm22 Transmedullary neuron that terminates in lobula layer 6 fine arborizations, and in lobula layers 4 and 5 with bleb-type arborizations. It displays fine arborizations in medulla layers M4, M6 and M8, and has bleb-type arborizations in layers M6 and M8. It is a cholinergic neuron (Varija Raghu et al., 2011). fly_anatomy.ontology VFB:FBbt_00003810 FlyBrain_NDB:10147 FBbt:00003810 lobula layer 4 lobula layer 5 lobula layer 6 adult cholinergic neuron
