General Information
Term transmedullary neuron TmR7 P and Y ID (Ontology) FBbt:00110130 (Fly Anatomy)
Definition Transmedullary wide-field neuron that arborizes in medulla layers M3, M7 and M8. It enters the medulla along a specific column and then extending its arborizations to cover two to ten columns. It projects to the lobula (Morante and Desplan, 2008).[ FlyBase:FBrf0204652 ]
Also Known As "TmP&Y R7" ; "TmR7 P and Y"
Comment Pre-synaptic terminals were assessed by labelling with a UAS-Synaptotagmin reporter (P\{UAS-HA-syt\} - FBtp0015803). The identification of dendrites and axons was done using a UAS-Dscam (P\{UAS-Dscam.exon17.1.GFP\} - FBtp0021447) or a UAS-tau (P\{UAS-tau-lacZ.O\} - FBtp0010033) reporter, respectively (Morante and Desplan, 2008).
