Summary: The researchers found a biomarker for major depressive disorder (MDD) in the folds of the brain’s outer covering, or gyri. The investigation, the first of its kind, linked MDD to the local gyrification index (LGI), a measure of cortical folding derived from brain scans. The study revealed that patients with MDD showed decreased cortical … Read more
