protocerebral neuroblast type I neuroblast neuroblast DALcl1 2011-07-07T04:28:29Z VFB:FBbt_00100545 FBbt:00100545 neuroblast DALcl1 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 DALcl2 (Lovick et al., 2013; Hartenstein et al., 2015). The ventral tract crosses the midline in the subellipsoid commissure (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 larva, terminal arborizations of primary DALcl1 dorsal neurons fill the anterior and medial inferior protocerebrum posterior to the elbow formed by the lobes of the mushroom body and ventral neurons innervate the lateral accessory lobe (LAL) (Hartenstein et al., 2015). In the adult, the anterior optic tubercle and bulb are major regions of secondary neuron arborization, as well as both LALs (Wong et al., 2013; Ito et al., 2013; Yu et al., 2013). neuroblast AOTUv3 fly_anatomy.ontology neuroblast DAL
