Brain Emotion Circuit Sparks as Teen Girls Size Up Peers

Press Release • July 15, 2009

What is going on in teenagers’ brains as their drive for peer approval begins to eclipse their family affiliations? Brain scans of teens sizing each other up reveal an emotion circuit activating more in girls as they grow older, but not in boys. The study by Daniel Pine, M.D., of the National Institute of Mental Health (NIMH), part of National Institutes of Health, and colleagues, shows how emotion circuitry diverges in the male and female brain during a developmental stage in which girls are at increased risk for developing mood and anxiety disorders.

Thinning Tissue in Right Half of Brain Signals Increased Risk of Inherited Depression

Science Update • May 08, 2009

In cases of familial depression, changes in tissue thickness in key brain structures in the right half of the brain may increase a person’s risk for developing depression, according to NIMH-funded researchers. Similar changes in the left half of the brain were linked to the severity of a person’s existing depression or anxiety symptoms. Based on their findings, the researchers proposed a possible mechanism for how these brain changes affect depression risk in the April 14, 2009, issue of the Proceedings of the National Academy of Sciences.
