| Description |
PET brain scans show chemical differences in the brain between addicts and non-addicts. The normal images in the bottom row come from non-addicts; the abnormal images in the top row come from patients with addiction disorders. These PET brain scans show that that addicts have fewer than average dopamine receptors in their brains, so that weaker dopamine signals are sent between cells. |
