General Information
Term larval posterior inferior protocerebrum ID (Ontology) FBbt:00007070 (Fly Anatomy)
Definition Compartment of the larval inferior protocerebrum found posterior medial to the larval superior clamp (medial inferior protocerebrum) (Hartenstein et al., 2015). The adult central complex arises from secondary axonal tracts of several lineages that invade this region and displace it during pupal development (Pereanu et al., 2010). A small region at its posterior edge remains and gives rise to the adult inferior clamp (posterior inferior protocerebrum) (Pereanu et al., 2010).[ FlyBase:FBrf0155900 FlyBase:FBrf0211016 FlyBase:FBrf0229672 ]
Also Known As "centro-posterior medial synaptic neuropil domain" ; "centroposterior medial compartment" ; "CPM" (for all, see Synonyms field below)
Comment Developmental relation to adult synaptic neuropil domain is a PC 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.
