Brain scans reveal resilience marker in 9/11 responders

Twenty-five years after the September 11 attacks, researchers at Mount Sinai have turned their attention not to what breaks the human mind under catastrophic trauma, but to what quietly sustains it. By scanning the brains of World Trade Center responders, scientists have identified a neurological signature in those who remained psychologically intact — a distinctive pattern in how the brain anticipates and processes positive experience.
