General Information
Term neuroblast BLP1 ID (Ontology) FBbt:00100625 (Fly Anatomy)
Definition Neuroblast whose neuronal lineage has relatively dorsal somas in the BLP group during the larval stage (Pereanu and Hartenstein, 2006; Hartenstein et al., 2015). Similar to BLP2, these neurons project anteriorly toward the junction between the optic lobe (or optic neuropil) and the ventrolateral protocerebrum (Hartenstein et al., 2015). During metamorphosis, the BLP3 and BLP4 somas migrate, to move dorsal to BLP1 and BLP2 (Lovick et al., 2013). In the adult its secondary lineage innervates the ventrolateral protocerebrum with additional projections to the posterior lateral protocerebrum and inferior protocerebrum (Wong et al., 2013).[ FlyBase:FBrf0194268 FlyBase:FBrf0223298 FlyBase:FBrf0223329 FlyBase:FBrf0229672 ]
Also Known As "neuroblast BLP1" ; "neuroblast VPNp&v1"
Comment VPNp4 lineage is a subset of VPNp&v1 (BLP1) (Schlegel et al., 2024 - FBrf0260535).
