General Information
Term adult doublesex TN1 (male) neuron ID (Ontology) FBbt:00047363 (Fly Anatomy)
Definition Doublesex-expressing neuron of the adult male that has its cell body in the on the ventral side of the ventral nerve cord, in a dense cluster between the prothoracic and mesothoracic neuromeres (Lee et al., 2002). They are part of the 12A hemilineage (Shirangi et al., 2016) and there are approximately 23 of these neurons per hemisphere (Pavlou et al., 2016). Some of these cells project bundled neurites dorsally to arborize in the tectulum and wing neuropils in the first two thoracic neuromeres, forming a triangular shape when viewed from the dorsal side (Shirangi et al., 2016). These cells are not found in the female.[ FlyBase:FBrf0159058 FlyBase:FBrf0210397 FlyBase:FBrf0210735 FlyBase:FBrf0232698 FlyBase:FBrf0234085 ]
Also Known As "doublesex-expressing Thoracic Neuron-1" ; "dsx-expressing Thoracic Neuron-1" ; "dsx-TN1"
