Cocaine Use Linked To Altered Gene Expression In Brain Reward Circuits

Distinct genetic changes in the brain’s reward circuitry are associated with cocaine use, including first-time use, withdrawal, and re-exposure to the drug after prolonged withdrawal, a new study indicates. The findings represent important information on how cocaine addiction reprograms gene expression and provide insight into the molecular basis of cocaine addiction in unprecedented detail. In […]
