Major Depression Associated with a Smaller Hippocampus.
A large international study has found that individuals with major depression have a significantly smaller hippocampus (an area of the brain associated with regulating emotions) than those without depression. Dr. Jim Lagopoulos, an associate professor at Brain and Mind Research Institute, says these findings reveal new information about our brain structures and the mechanisms that might underlie depression.
