General Information
Term adult VNC ventral unpaired median neuron ID (Ontology) FBbt:00052750 (Fly Anatomy)
Definition Unpaired neuron of the adult ventral nerve cord with its soma along the ventral midline (Ehrhardt et al., 2023). These are mainly efferent neurons with bilaterally symmetrical projections (Ehrhardt et al., 2023). There are around 13 of these cells in the thoracic neuromeres (Phelps et al., 2021).[ FlyBase:FBrf0247998 ]
Also Known As "adult UM neuron" ; "adult VUM neuron" ; "VUM"
Comment Confirmed by the first author of Phelps et al. (2021) that these are identical to their 'unpaired median' neurons, which were referred to as 'dorsal unpaired median' ('DUM') neurons in the preprint version of the paper.
