General Information
Term adult moonwalker descending neuron ID (Ontology) FBbt:00111308 (Fly Anatomy)
Definition Descending neuron whose soma is located on the midline, near the medial posterior protocerebrum of the adult brain (Bidaye et al., 2014). It arborizes bilaterally in the medial ventral protocerebrum and subesophageal zone (Bidaye et al., 2014). Axonal terminals are located in the subesophageal zone and bilaterally in the thoracic neuromeres (Bidaye et al., 2014). It is cholinergic (Cheong et al., 2024). This neuron is involved in triggering backward walking (Bidaye et al., 2014) and can do this in response to visual (Sen et al., 2017) and odor (Israel et al., 2022) stimuli. It develops from a larval mooncrawler descending neuron (Carreira-Rosario et al., 2018). There are two of these cells per hemisphere (Bidaye et al., 2014).[ FlyBase:FBrf0224613 FlyBase:FBrf0234928 FlyBase:FBrf0239825 FlyBase:FBrf0252931 ]
Also Known As "DNp50" ; "MDN" ; "MDN neuron"
