TmY8 FlyBrain_NDB:10176 fly_anatomy.ontology TmY8 Transmedullary Y wide-field neuron that terminates with bleb-type arborizations in lobula layers 4 and 5, and in lobula plate layers 1 and 3. It displays bleb-type arborizations in medulla layers M6 and M10, and has fine arborizations in medulla layers M1, M2, M4, M5 and M6 (Morante and Desplan, 2008; Fischbach and Dittrich, 1989). It is cholinergic (Konstantinides et al., 2022).
