brain Scans of cocaine craving

Left: When active cocaine users watched a video showing people taking cocaine and other cocaine-associated cues, the areas of the brain shown in orange "lit" up, or became more activated an indication that they were craving the drug. Right: When the subjects were told to inhibit their craving while watching the cocaine-cues video (cognitive inhibition), activity in the brain regions shown in blue decreased. The researchers say this deactivation is a way for the brain to "tune out" the cocaine cues and is an indication of their ability to inhibit craving.
