Assessing cue-induced brain response as a function of abstinence duration in heroin-dependent individuals: an event-related fMRI study.
The brain activity induced by heroin-related cues may play a role in the maintenance of heroin dependence.Whether the reinforcement or processing biases construct an everlasting feature of heroin addiction remains to be resolved.We used an event-related fMRI paradigm to measure brain activation in response to heroin cue-related pictures versus neut
