larval ellipsoid body-protocerebral bridge-gall neuron precursor

ID: FBbt_00051454

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).

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.
