General Information
Term	neuroblast DPLp1	ID (Ontology)	FBbt:00100603 (Fly Anatomy)
Definition	Neuroblast that forms a primary lineage with somas lateral to the larval mushroom body calyx, along with DPLp2, its tract converges onto the dorsal CP2/3 tract and enters the oblique posterior (obP) fascicle (Hartenstein et al., 2015) In the adult, its secondary lineage is also similar to that of DPLp2, entering the posterolateral neuropil surface at the base of the lateral horn and arborizing in the lateral horn and superior lateral protocerebrum (Wong et al., 2013). A long, medial branch follows the obP fascicle, crossing the mushroom body pedunculus and the brain midline, forming terminal arborizations along its trajectory in the posterior inferior protocerebrum of both hemispheres (Wong et al., 2013). A massive projection is directed ventrally along the vertical posterior tract into the posterior lateral protocerebrum and posterior wedge (Wong et al., 2013).[ FlyBase:FBrf0194268 FlyBase:FBrf0221412 FlyBase:FBrf0221438 FlyBase:FBrf0223298 FlyBase:FBrf0229672 ]
