General Information
Term larval ellipsoid body-protocerebral bridge-gall neuron precursor ID (Ontology) FBbt:00051454 (Fly Anatomy)
Definition Larval neuron that is a precursor to an ellipsoid body-protocerebral bridge-gall neuron in the adult (Lovick et al., 2017). It is a secondary neuron that develops from one of the DM1-4 neuroblasts (Lovick et al., 2017). From its posterior cell body, it projects anteriorly past the primordium of the protocerebrum then turns medially to contribute to a dense plexus of fibers at the posterior boundary of the fan-shaped body primordium (Lovick et al., 2017). From this plexus, anteriorly-directed filopodial tufts contribute to the posterior ellipsoid body primordium and another fiber projects to the primordium of the gall (Lovick et al., 2017).[ FlyBase:FBrf0236656 ]
Also Known As "larval ellipsoid body wedge neuron"
Comment Not clear if different types of cells connecting PB, EB and gall can be distinguished from one another at this stage - Lovick et al. (2017) refer only to the 'wedge' cells, but it may be possible to broaden this class to include precursors to other cells connecting these regions - https://orcid.org/0000-0002-1373-1705.
