TmY4
ID: FBbt_00003821
Transmedullary Y wide-field neuron that terminates with both fine and bleb-type arborizations in lobula layer 4 and in lobula plate layers 2, 3 and 4, but shows only fine arborizations in lobula plate layer 1. It displays both fine and bleb-type arborizations in medulla layer M8, but has only fine arborizations in medulla layer M3 and M4 (Morante and Desplan, 2008; Fischbach and Dittrich, 1989). It is cholinergic (Konstantinides et al., 2022).
Pre- versus postsynaptic innervation judged by scoring of terminal morphology from figures in Fischbach and Dittrich (1989) as assessed by FlyBrain Neuron DB.
