The neurotransmitter was assessed by the intersection of the expression of the VGAT-GAL4 driver (FBtp0069181) and an antibody against GABA (Raghu et al., 2013). FlyBrain_NDB:10150 Tm25 Transmedullary neuron that terminates in lobula layer 5 with bleb-type arborizations. It displays fine arborizations in medulla layers M1, M2, M4, M5, M6 and M9, and has bleb-type arborizations in layers M5 and M8. It is a GABAergic neuron. lobula layer 5 adult GABAergic neuron
