General Information
Term proximal medullary amacrine neuron Pm3 ID (Ontology) FBbt:00110066 (Fly Anatomy)
Definition Proximal medullary amacrine neuron that branches at the proximal surface of the medulla, with both branches forming a broad terminal arbor in medulla layer M9. The processes of different cells intermingle significantly, and the arbor density is heterogeneous. It occupies a peripheral intracolumnar position. It is GABAergic (Davis et al., 2020). There are around 35-40 of these cells per hemisphere (Nern et al., 2025).[ FlyBase:FBrf0213020 FlyBase:FBrf0228639 FlyBase:FBrf0244935 FlyBase:FBrf0262545 ]
Also Known As "CB3856" ; "Pm09" ; "Pm3"
