correlating the sites of maximal [ 3h ] diprenorphine displacement with the previously described distribution of the opioid peptides suggests that the perforant path fibers release enkephalins in stratum lacunosum moleculare of ca3 and stratum moleculare of the dentate gyrus , and that mossy fibers may release both dynorphins and enkephalins near stratum pyramidale of ca3 and stratum granulosum .
