embryonic/larval posterior superior medial protocerebrum

ID: FBbt_00007066

A synaptic neuropil subdomain of the larval brain that is located posterior and dorsal to the medial lobe of the mushroom body and which is separated from the anterior superior medial protocerebrum by a neuropil glial sheath slightly posterior to the vertical lobe of the mushroom body. Axons from this compartment converge with those from part of the clamp (CPL) to form the posterior transverse tract (PTT). It is the larval counterpart of the adult posterior superior medial protocerebrum.

Developmental relation to adult synaptic neuropil domains comes from a personal communication 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.
