Caption: Researchers led by Dr. Craig Powell, assistant professor of neurology and psychiatry, demonstrated with mice how a natural stress hormone called corticosterone can help lastingly decrease the fearful response associated with reliving a traumatic memory. The study focused on a mechanism called extinction, in which a memory gradually diminishes, but can be re-established by a small reminder of the original event.
