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). fly_anatomy.ontology VFB:FBbt_00048100 FBbt:00048100 dsx-TN1A adult premotor neuron adult cholinergic neuron adult prothoracic neuromere adult mesothoracic neuromere male courtship behavior, veined wing generated song production
