The Freedom Tower

The trauma of 9/11 appears to have altered brains, a new study suggests.
Magnetic resonance imaging of the brains of healthy adults more than three years after Sept. 11, 2001, shows areas that have less gray matter volume in those who were near ground zero on 9/11, compared with those who were much farther away. In various views, the brain areas of 9/11 people had lower gray matter volumn. Notably, all of these areas (which show up brighter in this image) are associated with the processing of emotion.
