General Information
Term transmedullary neuron Tm3Y ID (Ontology) FBbt:00003830 (Fly Anatomy)
Definition Transmedullary neuron that terminates in lobula layer 4 with bleb-like terminal arborizations. It has fine arborizations in medulla layers M1, M4, and M5, and has bleb-type arborization in medulla layers M1, M4, M9 and M10. It differs from the transmedullary neuron Tm3 or TmY3 in that an individual of a retinotopic set may or may not form branches in the lobula plate.[ FlyBase:FBrf0049410 ]
Also Known As "Tm3Y"
Comment Pre- versus postsynaptic innervation judged by scoring of terminal morphology from figures in Fischbach and Dittrich (1989) as assessed by FlyBrain Neuron DB.
