Training the brain to treat itself is a promising therapy for traumatic stress. The training uses an auditory or visual signal that corresponds to the activity of a particular brain region, called neurofeedback, which can guide people to regulate their brain activity. However, treating stress-related disorders requires accessing the brain’s emotional hub, the amygdala, which is located deep in the brain and difficult to reach with typical neurofeedback methods. Now a new imaging method has been tested that provides reliable neurofeedback on the level of amygdala activity and allowing people to alter their emotional responses through self-regulation of its activity.
