General Information
Term transmedullary neuron Tm3b ID (Ontology) FBbt:00110071 (Fly Anatomy)
Definition Transmedullary neuron that terminates in lobula layers 1 and 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 (Fischbach and Dittrich, 1989). It has a small branch at medulla layer M8 that projects towards medulla layer M10, which distinguishes it from the Tm3a (Tm3) neuron (Hasegawa et al., 2011).[ FlyBase:FBrf0049410 FlyBase:FBrf0213020 ]
