General Information
Term protocerebrum ID (Ontology) FBbt:00003627 (Fly Anatomy)
Definition The most anterior neuromere of the central nervous system, developing from neuroblasts of the labral and ocular segments (Urbach and Technau, 2003; Ito et al., 2014). The protocerebrum comprises many discrete neuropil regions including the central complex and mushroom bodies (Ito et al., 2014).[ FlyBase:FBrf0161020 FlyBase:FBrf0224194 ]
Also Known As"PR" ; "protocerebral neuromere"
CommentUrbach and Technau (2003) divide the protocerebrum into labral and ocular neuromeres.
