General Information
Term distal medullary amacrine neuron Dm9 ID (Ontology) FBbt:00111271 (Fly Anatomy)
Definition Distal medullary wide-field amacrine neuron with arbors that span multiple columns in layers M1 and M6A and columnar processes between these two layers. The processes in M2 and M5 occupy a central column position and are closely associated with R7 and R8 photoreceptor axons, covering around 7 columns. There are around 110 Dm9 neurons per hemisphere. They are glutamatergic (Davis et al., 2020).[ FlyBase:FBrf0222324 FlyBase:FBrf0228639 FlyBase:FBrf0244935 FlyBase:FBrf0252485 ]
Also Known As "Dm9" ; "glia-like cell"
