antennal lobe neuroblast neuroblast BAla1 Neuroblast that generates antennal lobe projection neurons with cell bodies in a cluster found ventral to the antennal lobe in the adult (Jefferis et al., 2001; Yu et al., 2013). This lineage mainly generates neurons with only short branches into the antennal lobe and more extensive ones into the adjacent basal brain compartments posterior to the antennal lobe. It also generates a few oligoglomerular and multiglomerular primary projection neurons (Das et al., 2013). Some neurons of this lineage, referred to as extra-antennal BAla1 projection neurons, do not enter the antennal lobe (Das et al., 2013).
