During exposure to fearful faces migraine frequency was associated with increased activation in the right postcentral gyrus and right inferior parietal lobule, and estimated lifetime number of migraine attacks were related to increased right postcentral gyrus and right angular gyrus activation. Increased neural response related to happy faces showed significant association with migraine frequency in the right caudate nucleus and right putamen. Significantly activated clusters are shown at pFWE = 0.05, corrected for multiple comparison. Coordinates are in Montreal Neurological Institute (MNI) space.
