Using a novel brain-mapping technique, researchers found that the frontostriatal salience network was expanded nearly twofold in the brains of most individuals studied with depression compared with controls.
Precision functional mapping is a relatively new approach to brain mapping in individuals that uses large amounts of fMRI data from hours of scans per person. The technique has been used to show differences in brain networks between and in healthy individuals but had not been used to study brain networks in people with depression.
