The present study investigated the relationship between motivation to change cocaine use and cue-elicited brain activity in cocaine-dependent individuals using two conceptualizations of “motivation to change:” current treatment status and self-reported motivation to change. Thirty-eight cocaine dependent individuals completed an assessment and an fMRI cocaine cue-reactivity task. Both treatment-seeking (n=14) and motivated participants had lower activation to cocaine cues in a wide variety of regions in the frontal, occipital, temporal, and cingulate cortices relative to non-treatment-seeking and less motivated participants.
