type I neuroblast neuroblast BLAv2 2011-07-11T03:24:03Z neuroblast VLPl3 Neuroblast found in a relatively ventral location in the basolateral anterior (BLA) group, along the anterior edge of the optic lobe primordium, during the larval stage (Pereanu and Hartenstein, 2006; Hartenstein et al., 2015). Its primary lineage projects posteriorly, then medially, entering the ventrolateral protocerebrum (VLP) and some fibers continue medially to the great commissure (GC) (Hartenstein et al., 2015). It produces two secondary hemilineages, a posterior one that follows the tract of primary lineage through the VLP and GC and a medial one, that crosses the midline posterior to the central complex (Wong et al., 2013). During metamorphosis, the hemilineage clusters move apart and the posterior hemilineage gains an additional, dorsal, branch (Lovick et al., 2013). FBbt:00100613 VFB:FBbt_00100613 neuroblast VLPl2 neuroblast BLAv2 The VLPl3 clone from Ito et al. (2013) is a subset of the VLPl2 clone (Schlegel et al., 2024 - FlyBase:FBrf0260535). Hemilineage classes not created for this NB as three groups were identified in Schlegel et al. (2024) and it is unclear how hemilineages should be grouped. fly_anatomy.ontology neuroblast BLA
