Exaggerated amygdala response to masked facial stimuli in posttraumatic stress disorder: a functional MRI study.


BACKGROUND Converging lines of evidence have implicated the amygdala in the pathophysiology of posttraumatic stress disorder (PTSD). We previously developed a method for measuring automatic amygdala responses to general threat-related stimuli; in conjunction with functional magnetic resonance imaging, we used a passive viewing task involving masked… (More)
