General Information
Term embryonic/larval posterior lateral protocerebrum ID (Ontology) FBbt:00007723 (Fly Anatomy)
Definition A synaptic neuropil domain located ventro-postero-laterally in the larval central brain (posterior part of BPL). Anteriorly, the great commissure (BLAv1,BLD5) defines the boundary, in the coronal plane, with the ventrolateral protocerebrum (VLP). Dorsally, there is a slim border with the superior lateral protocerebrum (SLP). Medially, a virtual sagittal plane intersecting the CP1v tract and the Balp2/3 tract separates the this domain from the ventromedial cerebrum (VMCp). Laterally, a glial septum and BLP1/2 tract separates it from the lobula. The clamp is dorso-medial and laterally, the boundary is a continuation posteriorly of the clamp-VLP border i.e. the virtual plane defined by the LEFp(CP1v) and PLF(CP2/3v) fascicles to LEFa(DALv1) fascicle (Hartenstein et al., 2015). The superior lateral protocerebrum (SLP) forms a slim ventral border with the PLP, which is defined by the entry point of the trSI(BLD1-4) fascicle; in addition, a higher synaptic density (e.g. as assayed using the presynaptic marker bruchpilot) demarcates the posterior SLP from the PLP.[ 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.
