Some Research History Psychological Factors in Headache and Orofacial Pain Structural Equation Model to Predict Orofacial Pain Brain Mechanisms of Emotion Processing with fMRI Brain Mechanisms of Pain Processing with fMRI
Anger and Fear Affect Pain Related Brain Activity Patients with Chronic Pain Affected by Stress & Emotion Model for Face Pain Brief Painful Heat Stimulation Functional Magnetic Resonance Imaging fMRI – Blood Oxygen Level – Brain Activity
Brain Mechanisms of Pain Model Brief Repeated Trials of Painful Heat Stimulation Pain alone Pain with Anger Recall Pain with Fear Recall Observe the effect of anger and fear on pain Start with healthy, pain-free individuals
