Abstract
BACKGROUND: Accumulating evidence suggests that migraine patients present abnormal brain responses to salient sensory and emotional stimuli. However, it is still unclear whether this is a generalized or domain-specific phenomenon. Employing a well-validated fMRI paradigm, we investigated pain empathic reactivity across two domains: observation of physical pain (noxious stimulation) and affective pain (facial expressions). On the basis of a generalized hyperexcitability/hyperreactivity in migraine, we hypothesized abnormal responses to both dimensions of pain empathy.
