obsolete centro-posterior intermediate synaptic neuropil domain true A synaptic neuropil domain of the larval brain located posterior to the medial lobe of the mushroom body. It is separated from the centro-posterior medial compartment by the antenno-cerebral tract to which it is connected by a branch. Its axons project mainly into the posterior transverse tract and it receives a branch of the antenno-cerebral tract. FBbt:00007125 This term has been obsoleted because it has been superseded by the term embryonic/larval clamp (FBbt:00111204) - mc150915. 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. As there is some non-isometric growth of compartments during larval stages, some elements of this description may not apply to the third instar larval brain - ds080222. fly_anatomy.ontology embryonic/larval superior clamp
