Two brain scans side by side one labeled "Normal" and the other labeled "Drug Abuse". Both scans are color-coded with the normal scan on the left and the drug abuse on the right.
Each brain scan shows a large yellow area around the perimeter with a blue area in the center. The normal scan shows a large amount of red mixed into the yellow area whereas the drug abuse scan has very little red in comparison. The background of both scans is black making the colors of the scans stand out.
