Full Text: Healthy adults who were close to the World Trade Center during the terrorist attacks on September 11, 2001, have less gray matter in key emotion centers of their brains compared with people who were more than 200 miles away, according to a new Human Ecology study.

The study--one of the first to look at the effects of trauma on the brains of healthy adults--follows a Cornell study by the same authors that found people living near the World Trade Center on 9/11 have brains that are more reactive to such emotional stimuli as photographs of fearful faces. Combined, the two studies provide an emerging picture of what happens in the brains of healthy people who experience a traumatic event. Both were conducted by postdoctoral fellow Barbara Ganzel.

The smaller volume of gray matter--composed largely of cells and capillary blood vessels--found was in areas that process emotion and may be, Ganzel said, the brain's normal response to trauma. The subjects in the study did not suffer from any mental or physical health disorders.
