General Information
Term adult doublesex TN1A (male) neuron ID (Ontology) FBbt:00048100 (Fly Anatomy)
Definition TN1 neuron that projects mostly posteriorly into the dorsal mesothoracic neuromere, innervating both hemispheres, with a branch also projecting anteriorly into the dorsal prothoracic neuromere (Shirangi et al., 2016). It is synapsed to the hg1 motorneuron and it is involved in male sine, but not pulse, song generation (Shirangi et al., 2016; Lillvis et al., 2024). It is cholinergic (Lillvis et al., 2024). There are approximately 11 of these cells per hemisphere and some express fruitless in addition to doublesex (Lillvis et al., 2024).[ FlyBase:FBrf0232698 FlyBase:FBrf0258823 ]
Also Known As "dsx-TN1A"
Comment Synapsing demonstrated by GRASP and functional experiments (Shirangi et al., 2016).
