Adult Motor neuron Nervous system

Motor neuron that innervates the external muscle of fourth axillary hg1, ipsilaterally (O'Sullivan et al., 2018; Ehrhardt et al., 2023. 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). (Shirangi et al., 2013)
