General Information
Term transmedullary neuron Tm12 ID (Ontology) FBbt:00003800 (Fly Anatomy)
Definition Transmedullary wide-field neuron that terminates in lobula layers 3 and 5 with bleb-type arborizations. It displays fine arborizations in medulla layers M1, M2, M3, M4, M5, M6, M8 and M9, and has bleb-type arborizations in layers M6 and M9 (Fischbach and Dittrich, 1989; Morante and Desplan, 2008). It is a cholinergic neuron (Varija Raghu et al., 2011).[ FlyBase:FBrf0049410 FlyBase:FBrf0204652 FlyBase:FBrf0212356 ]
Also Known As"Tm12"
CommentThe neurotransmitter was assessed by co-labelling cells with a Cha-GAL4.7.4 driver (FBtp0014830) and an anti-ChAT antibody (Varija Raghu et al., 2011). Pre- versus postsynaptic innervation assessed by labelling with the dendritic marker Dscam (P\{UAS-Dscam.exon17.1.GFP\} - FBtp0021447), or with a presynaptic marker (UAS-Synaptotagmin:HA - FBtp0015803) (Morante and Desplan, 2008). The morphology of terminals was judged from figures in Fischbach and Dittrich (1989) as assessed by FlyBrain Neuron DB.
