protocerebral neuroblast type I neuroblast neuroblast DALcl2 2011-07-07T04:29:57Z neuroblast AOTUv4 neuroblast DALcl2 fly_anatomy.ontology FBbt:00100546 DAL neuroblast whose primary and secondary lineages form dorsal and ventral tracts that enter the neuropil near the mushroom body spur and project medially, similar to DALcl1 (Lovick et al., 2013; Hartenstein et al., 2015). The ventral tract enters the lateral ellipsoid fascicle (Lovick et al., 2013; Hartenstein et al., 2015). The dorsal tract crosses the dorsal surface of the mushroom body pedunculus (Lovick et al., 2013; Hartenstein et al., 2015). In the adult, its secondary neurons have more widespread arbors than DALcl1, reaching the anterior optic tubercle, bulb, lateral accessory lobe, superior medial protocerebrum and inferior protocerebrum (Wong et al., 2013; Ito et al., 2013; Yu et al., 2013).
