Brain Imaging
Total Running Time: 6:15 min.
The ability to look inside the brain through electronic imaging has yielded many
advances in the study of addiction, allowing researchers to focus on triggers like
dopamine, the neurotransmitter that defines the brain's pleasure pathways. At the
Brookhaven National Laboratory, Nora Volkow shows John, a 43-year-old
methamphetamine user, an MRI image of his brain next to a "normal" one. Despite
visual evidence of damage, John seems ambivalent about quitting. "Our brain has a
tremendous capacity for recovery," insists Volkow, suggesting that John's brain can heal
itself - if he can stay off drugs.
