Chronic morphine exposure induces dependence. Abstinence from the drug causes withdrawal symptoms. Many previous studies have investigated the neural substrate of morphine withdrawal symptoms. In this study, we employed manganese-enhanced MRI (MEMRI) technique to map accumlative brain activities in morphine-treated rat in a 24-hour period during spontaneous withdrawal.
