title: Evidence for the co-localization of somatostatin- and methionine-enkephalin-like immunoreactivities in raphe and gigantocellularis nuclei.
abstract: Somatostatin-like and methionine-enkephalin-like immunoreactivities were co-localized in neurons in the raphe nuclei and the nucleus gigantocellularis among immunoreactive cells stained for either one of these putative neurotransmitters. Their colocalization suggests that they form a subset of these two peptide populations and may serve as a major inhibitory system within the medullary reticular nuclei.
