Its soma is found in the ventral mesothoracic neuromere (Ehrhardt et al., 2023). It has dense arbors in the ipsilateral anterior dorsal mesothoracic neuromere, including the wing neuropil, with some fibers extending slightly into the contralateral hemisphere (O'Sullivan et al., 2018; Ehrhardt et al., 2023). In the male, it plays a role in courtship song generation (O'Sullivan et al., 2018). VFB:FBbt_00048109 fly_anatomy.ontology O'Sullivan et al. (2018) say it is specific for pulse song, Ehrhardt et al. (2023) say sine song. I2_MN i2 MN cell body rind of adult mesothoracic neuromere
