 The interneurons of the stratum lucidum are generally found to be local circuit neurons remaining within the CA3 region.A majority of the interneuron axons remain within the stratum lucidum but some also extend to the stratum radiatum and stratum lacunosum-molecular above the radiatum as well as to the CA1 and hilur regions.In hippocampus anatomy, the stratum pyramidale is one of seven layers, or stratums, that make up the entire neural structure.
