neuroglioblast neuroblast CM4 fly_anatomy.ontology central complex neuroblast W VFB:FBbt_00050252 FBP4 Type II centromedial neuroblast of the posterior deutocerebrum (Pereanu and Hartenstein, 2006; Hartenstein et al., 2015). It gives rise to a small number of glial cells (Viktorin et al., 2011). Its primary lineage contributes to the fan-shaped body primordium (Riebli et al., 2013; Hartenstein et al., 2015). One group of its secondary neurons enters the neuropil at the level of protocerebral bridge glomeruli 8-9 and includes central complex columnar neurons (Lovick et al., 2013; Andrade et al., 2019). Other main secondary tracts include one that enters the ventromedial cerebrum and joins the longitudinal ventral posterior-lateral fascicle and one that turns dorsally into the superior medial longitudinal fascicle (Lovick et al., 2013). Its secondary lineage mainly arborizes in the superior medial protocerebrum and central complex (Ito et al., 2013). FBbt:00050252 The EBp1 clone from Ito et al.
