Mapping of Morphine-Induced OPRM1 Gene Expression Pattern in the Adult Zebrafish Brain

This study provides a detailed map of oprm1 localization in the brain, which includes previously unreported oprm1 in the habenula of teleost. Presence of oprm1 in multiple brain sites implies multiple action targets of morphine and potential brain functions which could include reward, cognitive and negative emotions.
