This compartment contacts the antennal lobe posteriorly, and is lateral to the lateral accessory lobe and ventromedial cerebrum. It grows anteriorly during larval development. It is the larval counterpart of the adult ventrolateral protocerebrum. Developmental relation to adult synaptic neuropil domains comes from a personal communication from Volker Hartenstein. Note - description of relative location of brain structures in this definition is based on Younossi-Hartenstein et al., 2003 description of the first instar larval brain and Pereanu et al., 2010 third instar larval brain.
