A cholinergic hub in the nucleus accumbens gates opioid-reward learning - Nature

Cell-type-specific opioid blockade in accumbal cholinergic interneurons abolishes morphine-reward learning without impairing analgesia and decouples morphine-evoked dopamine elevations from acetylcholine dips, suggesting pro-cholinergic strategies to limit early opioid reward acquisition.
