General Information
Term posterior lateral protocerebrum ID (Ontology) FBbt:00040044 (Fly Anatomy)
Definition A bilaterally paired synaptic neuropil domain of the adult that contains many glomeruli and is located behind the posterior ventrolateral protocerebrum (PVLP) and above the wedge. The mid-level of the posterior lateral protocerebrum (PLP) is separated from the PVLP by the great commissure, but above and below this the two neuropils are contiguous. The PLP houses many optic glomeruli formed by the terminals of neurons projecting from the optic lobe, primarily from the lobula plate. The boundary with the PVLP is defined by the boundary between these glomeruli that have different origins (lobula or lobula plate).[ FlyBase:FBrf0193607 FlyBase:FBrf0212704 FlyBase:FBrf0224194 ]
Also Known As "PLP" ; "posteriolateral protocerebrum" ; "posterior-lateral protocerebrum" (for all, see Synonyms field below)
Comment The PLP corresponds to almost all of the plpr of Otsuna and Ito (2006) and to the caudal ventrolateral protocerebrum (CVLP) and lateral part of the superpeduncular protocerebrum (SPP) of Chiang et al. (2011) (Ito et al., 2014).
