Description
Obsessive-compulsive disorder. Coloured Positron Emission Tomography (PET) scans of a human brain, showing active areas in obsessive compulsive disorder. The brain is sectioned axially (left), sagittally (centre), coronally (at right). In this patient, positive correlations (activity increases as symptoms get stronger) are in the top row, seen coloured in the left orbital region, prefrontal, left frontal gyri & thalamus. Negative correlation (activity decreasing as symptoms strengthen) are in the bottom row in the right frontal gyrus and parietal regions. Active areas coloured red/yellow show blood flow detected by a radioactive tracer.
