General Information
Term larval MP1 neuron ID (Ontology) FBbt:00001599 (Fly Anatomy)
Definition Interneuron residing slightly anterior and ventral to the posterior commissure in the corner formed by the connectives and the posterior commissure (Bossing and Technau, 1994). Its ipsilateral projection bifurcates in an anterior and posterior branch (which spans up to three neuromeres) that run within the medial sector of the connective. It is a peptidergic neurosecretory cell (Manning et al., 2012).[ FlyBase:FBrf0072659 FlyBase:FBrf0219785 ]
Also Known As "midline precursor 1 cell"
