Morphine is a potent analgesic with a high addictive potential. In this study we have shown a difference in brain connectivity related to drug-seeking behavior involving key neural decision and reward systems using rs-fMRI. The finding contributes to a better understanding of the neural underpinnings of opioid addiction and could help in a better assessment of relapse risk in individuals.
