Journal ArticleDOI
Cue-Induced Cocaine Craving: Neuroanatomical Specificity for Drug Users and Drug Stimuli
Hugh Garavan,John Pankiewicz,Alan S. Bloom,Jung-Ki Cho,Lori Sperry,Thomas J. Ross,Betty Jo Salmeron,Robert C. Risinger,Dan Kelley,Elliot A. Stein +9 more
TL;DR: The data suggest that cocaine craving is not associated with a dedicated and unique neuroanatomical circuitry; instead, unique to the cocaine user is the ability of learned, drug-related cues to produce brain activation comparable to that seen with nondrug evocative stimuli in healthy comparison subjects.
Journal ArticleDOI
Amygdala response to both positively and negatively valenced stimuli.
TL;DR: A role for the amygdala in processing emotional stimuli that extends beyond negative and fearful stimuli is demonstrated, and arousal level is clearly demonstrated to modulate the amygdala response.
Journal ArticleDOI
Neural correlates of high and craving during cocaine self-administration using BOLD fMRI.
Robert C. Risinger,Betty Jo Salmeron,Thomas J. Ross,Shelley L. Amen,Michael Sanfilipo,Raymond G. Hoffmann,Alan S. Bloom,Hugh Garavan,Elliot A. Stein +8 more
TL;DR: This study provides the first evidence in humans that changes in subjective state surrounding cocaine self-administration reflect neural activity of the endogenous reward system.
Journal ArticleDOI
Cocaine administration decreases functional connectivity in human primary visual and motor cortex as detected by functional MRI
Shi-Jiang Li,Bharat B. Biswal,Zhu Li,Robert C. Risinger,Charles Rainey,Jung Ki Cho,Betty Jo Salmeron,Elliot A. Stein +7 more
TL;DR: It is suggested that the observed changes in low frequency components after acute cocaine administration during a resting, no‐task situation may be used as a baseline reference source when assessing the effects of cocaine on task‐driven activation or on mesolimbic dopamine pathways.
Journal ArticleDOI
Neural responses to acute cocaine administration in the human brain detected by fMRI.
Peter R. Kufahl,Zhu Li,Robert C. Risinger,Charles Rainey,Gaohong Wu,Alan S. Bloom,Shi-Jiang Li +6 more
TL;DR: It is suggested that the dopaminergic pathways and the hierarchical brain networks may participate in mediating cocaine reward processes, associative learning, motivation, and memory in cocaine addiction in the human brain.
