Summary:
-
Expanded Brain Network
Researchers have found that individuals with depression have a frontostriatal salience network that is 73% larger compared to healthy individuals. This network takes up more brain surface area, while other neighboring networks are smaller. -
Methodology
The study utilized precision functional mapping, analyzing numerous fMRI scans from both depressed and healthy participants. This approach allowed accurate measurement of brain network sizes. -
Implications and Future Research
The findings suggest that an expanded brain network could be a risk factor for developing depression, rather than a consequence. The research also indicates that this network’s size remains constant regardless of mood changes or treatment, potentially paving the way for personalized treatments.
