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). 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). FBbt:00040044 plpr CVLP VFB:FBbt_00040044 ventrolateral neuropils
