General Information
Term adult mesothoracic VUM neuron 4 ID (Ontology) FBbt:00052755 (Fly Anatomy)
Definition Adult mesothoracic VUM neuron with a curved main fiber in the ventral nerve cord that has little arborization around it (Ehrhardt et al., 2023). 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).
Also Known As "adult T2VUM4 neuron" ; "T2VUM4"
Comment 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).
