A Nonpeptide Morphine-Like Compound: Immunocytochemical Localization in the Mouse Brain

Abstract
A nonpeptide morphine-like compound (MLC) which cross reacts with morphine-specific antibodies has been localized with the use of immunocytochemistry. This morphine-like compound is found in neuronal perikarya or processes (or both) in nuclei related to vestibular, cerebellar, and raphe systems.
