General Information
Term ps1 motor neuron ID (Ontology) FBbt:00047248 (Fly Anatomy)
Definition Motor neuron that arborizes in the wing neuropil and innervates the mesothoracic pleurosternal muscle 59 (pleurosternal 1), ipsilaterally (Ehrhardt et al., 2023). 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).[ FlyBase:FBrf0223321 FlyBase:FBrf0240039 ]
