The identification of dendrites and axons was done using a UAS-Dscam (P{UAS-Dscam.exon17.1.GFP} - FBtp0021447) or a UAS-tau (P{SUAS-tau-lacZ.O} - FBtp0010033) reporter, respectively (Morante and Desplan, 2008). VFB:FBbt_00110135 fly_anatomy.ontology Dm1-5 FBbt:00110135 Distal medullary wide-field amacrine neuron whose cell body is located in the cell body rind of the medulla. It has a distinct tri-stratified layer pattern, branching extensively in medulla layers M1, M3B and M5. Its arbor resembles an ellipse, with the long axis aligned with the dorsal-ventral axis, and covering less than 10 columns. The processes in M1 and M3B to M5 are located in an intracolumnar position. There are around 300 Dm10 neurons per hemisphere. They are GABAergic (Davis et al., 2020). distal medullary amacrine neuron Dm1-5 Dm10 optic lobe wide-field columnar neuron medulla sublayer M3B
