内容简介:

Substance use disorder (SUD), also known as drug addiction, constitutes a major public health problem. Understanding the neural circuit plasticity that occurs during the transition from initial drug exposure and reinforced drug taking, to compulsive drug taking behaviors (often followed by repetitive withdrawals from and relapses to the drug) is critically important in the development of more efficacious treatments for SUDs. Using resting-state functional magnetic resonance imaging (fMRI), we first identified distinct “go” and “stop” brain circuits, the imbalance of which was associated with compulsive behaviors of addictionin human drug users. Based upon these findings, a longitudinal study was designed using an animal model to examine thecausal relationships between drug taking, neural circuitry changes, and behavior alterations in addiction. A neuromodulation-based strategy is proposedfor the treatment of addiction and related mental disorders such as gambling and internet addiction.
