receives synaptic input in region sends synaptic output to region medulla layer M1 medulla layer M2 medulla layer M3 medulla layer M9 medulla intrinsic columnar neuron medulla intrinsic neuron Mi8 VFB:FBbt_00003783 medullary intrinsic neuron Mi8 Pre- versus postsynaptic innervation judged by scoring of terminal morphology from figures in Fischbach and Dittrich (1989) as assessed by FlyBrain Neuron DB. 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). Probably an atypical Mi1 (Nern et al., 2025 - FBrf0262545). FBbt:00003783 Mi8 fly_anatomy.ontology FlyBrain_NDB:10107 Medulla intrinsic neuron with a bushy mix of bleb-type and fine terminal arborization in layers M1-3. The projection of this neuron branches at the boundary with M10 to form varicose recurrent terminal specializations that extend back through M9. Mi8 adult GABAergic neuron
