Both structural and functional abnormalities in these areas have been found in depression.
Decreased hippocampal volumes (10, 25) have been noted in subjects with depression..
What chemical do people with depression have less of in their brain?
Low dopamine levels make people and animal models less likely to work toward achieving a goal.
