Its soma is found ventrally between the meso- and meta-thoracic neuromeres (Ehrhardt et al., 2023). It forms dense arbors in the dorsal mesothoracic neuromere, including the wing neuropil, with extensions into the contralateral hemisphere (O'Sullivan et al., 2018; Ehrhardt et al., 2023). In the male, it plays a role in pulse song generation (Shirangi et al., 2013; O'Sullivan et al., 2018; Ehrhardt et al., 2023). ps1_MN ps1 MN VFB:FBbt_00047248 flight control muscle motor neuron bilateral
