This image shows MRI scans of the brain and has text describing the results. The description of the image follows:

Drug Abuse and Decisionmaking: Researchers used functional magnetic resonance imaging (fMRI) to measure patterns of regional brain activity while abstinent methamphetamine abusers performed two tasks, one that required decisionmaking and one that required only a simple response. Participants who showed greater activity in selected brain regions (circled and highlighted in the brain images shown below) during the decisionmaking task than during the response task were likely to remain abstinent. Patients who showed far less activity during the decisionmaking task than during the simple response task were likely to relapse to methamphetamine abuse.

The regions of the brain that are circled are listed below:
