part of superior lateral protocerebrum synaptic neuropil subdomain posterior superior lateral protocerebrum 2009-08-13T04:49:31Z PSLP Boundaries defined by Ito et al. (2014) (used to define this term) differ slightly from those defined for pslpr in Otsuna and Ito, (2006). There is no prominent natural boundary that clearly separates the posterior and anterior superior lateral protocerebrum. A frontal plane extrapolated from the boundary of the PVLP and PLP, which corresponds to the anterioposterior level of the great commissure, is used as a practical boundary.
