General Information
Term distal medullary amacrine neuron Dm20 ID (Ontology) FBbt:00111281 (Fly Anatomy)
Definition Distal medullary wide-field amacrine neuron whose cell body is located in the dorsal and ventral regions of the cell body rind of the medulla. Its arbor is mainly located in the M3B layer, though there are branches in more proximal and distal layers, and processes branch multiple times between the edge of M1 and M3B layers. The arbor varies in shape between cells, covering 50-100 columns, and overlapping considerably. The processes are located in a peripheral intracolumnar position, similar to Dm12. There are around 50 Dm20 neurons per hemisphere.[ FlyBase:FBrf0228639 ]
Also Known As "Dm20"
