It has neurites that project straight anteriorly and posteriorly along the dorsal midline, and more lateral arborizations that project outwards from the midline like the points of a star (Ehrhardt et al., 2023). It is a neuromodulatory neuron that innervates wing muscles (Ehrhardt et al., 2023). adult T2VUM4 neuron FBbt:00052755 T2VUM4 mesVUM-PM fly_anatomy.ontology VFB:FBbt_00052755 Ehrhardt et al. (2023) seem fairly confident that T2VUM4 matches blowfly mesVUM-PM (innervates all DLMs and DVMs), but drosophila muscles were not definitively assigned to individual VUMs in this study. Likely to be octopaminergic or tyraminergic (Ehrhardt et al., 2023).
