General Information
Term transmedullary neuron Tm22 ID (Ontology) FBbt:00003810 (Fly Anatomy)
Definition Transmedullary neuron that terminates in lobula layer 6 fine arborizations, and in lobula layers 4 and 5 with bleb-type arborizations. It displays fine arborizations in medulla layers M4, M6 and M8, and has bleb-type arborizations in layers M6 and M8. It is a cholinergic neuron (Varija Raghu et al., 2011).[ FlyBase:FBrf0049410 FlyBase:FBrf0212356 ]
Also Known As "Tm22"
Comment The 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 judged by scoring of terminal morphology from figures in Fischbach and Dittrich (1989) as assessed by FlyBrain Neuron DB.
