Its large soma is found in the ventral mesothoracic neuromere and it has dense arborization, restricted to the ipsilateral hemisphere, in the dorsal mesothoracic neuromere, including the wing neuropil (O'Sullivan et al., 2018; Ehrhardt et al., 2023). In males, it is required for normal sine song (Shirangi et al., 2013; Ehrhardt et al., 2023) and also plays a role in pulse song generation (O'Sullivan et al., 2018). It is a fruitless vMS2 neuron (Cheong et al., 2024). fly_anatomy.ontology adult fruitless vMS2 neuron unilateral
