General Information
Term DLM motor neuron ID (Ontology) FBbt:00048112 (Fly Anatomy)
Definition Motor neuron that innervates a dorsal longitudinal indirect flight muscle. They have dendritic arbors in the medial dorsal mesothoracic neuromere (wing neuropil) that extend into both hemispheres (Ikeda and Koenig, 1988; O'Sullivan et al., 2018). They all exit the mesothoracic neuromere via the posterior dorsal mesothoracic nerve (Ikeda and Koenig, 1988). DLMN1-4 are similar to each other, having clustered somas and each innervating an ipsilateral muscle (Ikeda and Koenig, 1988). DLMN5 innervates two contralateral (to its soma) muscles and has its soma separate from DLMN1-4 (Ikeda and Koenig, 1988). Activation of these neurons increases wing stroke amplitude during flight (Ehrhardt et al., 2023).[ FlyBase:FBrf0048552 FlyBase:FBrf0240039 ]
