General Information
Term transmedullary Y neuron TmY8 ID (Ontology) FBbt:00003826 (Fly Anatomy)
Definition 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).[ FlyBase:FBrf0049410 FlyBase:FBrf0204652 FlyBase:FBrf0253187 ]
Also Known As"TmY8"
CommentPre- versus postsynaptic innervation judged by scoring of terminal morphology from figures in Fischbach and Dittrich (1989) as assessed by FlyBrain Neuron DB.
