General Information
Term distal medullary amacrine neuron Dm11 ID (Ontology) FBbt:00111272 (Fly Anatomy)
Definition Distal medullary wide-field amacrine neuron whose cell body is located in the dorsal region of the cell body rind of the medulla. Its primary neurite extends beyond M6A layer, and then turns back, forming recurrent, columnar processes from M6A to M1, and into the first optic chiasm. The arbor varies in shape between cells, covering around 9 columns and showing tiling. The terminals of these cells in M6A collectively occupy the whole layer, whereas in the other layers the processes are thin, with each process occupying only one column, and being associated with R7 and R8 photoreceptor axons. There are around 70 Dm11 neurons per hemisphere. They are glutamatergic (Davis et al., 2020).[ FlyBase:FBrf0228639 FlyBase:FBrf0244935 FlyBase:FBrf0252485 ]
Also Known As "Dm11"
