part of larval deutocerebrum embryonic/larval ventromedial cerebrum larval VMC baso-posterior medial compartment FBbt:00007063 larvalbrain_neuropil:437 VFB:FBbt_00007063 larvalbrain_neuropil:615 One of a group of synaptic neuropil domains of the larval brain which are located ventral to the mushroom body and are grouped around the long axon tracts connecting the larval protocerebrum to the ventral nerve cord. This medially located compartment contacts the antennal lobe posteriorly. The lateral cervical tract ascends through the center of this compartment. It is the larval counterpart of the adult ventromedial neuropils. larval baso-posterior midbrain larval ventromedial cerebrum basoposterior medial compartment BPM 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. fly_anatomy.ontology synaptic neuropil domain
