Study Summary
The purpose of the current study is to develop a better understanding of the brain mechanisms involved in psychological treatments for posttraumatic stress disorder (PTSD). This project will build on past research using script-driven imagery in our lab by investigating brain activity in areas activated during exposure to trauma-related cues. This project will also develop new knowledge concerning volitional control of those areas. The ultimate goal of this study is a better understanding of whether volitional control of these brain areas will improve therapeutic outcomes. This process will first be piloted in a sample of healthy controls. This will allow investigators to refine the methodology prior to recruiting a sample with PTSD.
Primary Outcome
Support vector machine decodings of functional MRI data acquired during volitional engagement or disengagement of emotional arousal. Each decoding represents the Euclidean distance and direction (either positive or negative) of the functional MRI data volume with respect to the patient's support vector machine decision hyperplane. Positive distances denote engagement of emotional arousal and negative distances denote disengagement of emotion arousal. Distance represents the magnitude of volition
Interventions
