Trauma Brain Science

Stress is our internal response to an experience that our brain perceives as threatening or challenging. Trauma is our response to an experience in which we feel powerless or lacking agency. Until now, researchers have treated these conditions as different, but they actually lie along a continuum. Dr. Elizabeth Stanley explains the significance of this continuum, how it affects our resilience in the face of challenge, and why an event that's stressful for one person can be traumatizing for another.

Early studies of the human brain used a simple method: Wait for misfortune to strike - strokes, seizures, infectious diseases, horrendous accidents - and see how victims coped. In many cases their survival was miraculous, if puzzling. Observers were amazed by the transformations that took place when different parts of the brain were destroyed, altering victims' personalities. With the lucid, masterful explanations and razor-sharp wit his fans have come to expect, Kean explores the brain's secret passageways.
