MedicalResearch.com Interview with: Chun Yuen Fong Post-doc research fellow Center for Cognitive and Evolutionary Science University of Tokyo  MedicalResearch.com: What is the background for this study? Response: Migraine is one of the most prevalent neurological disorders worldwide. However, what exactly trigger a migraine episode is not entirely clear despite years of research. Moreover, migraine sufferers often report having excessive sensitivity to light and certain patterns during the headache-free period. Some researchers suggested that such abnormal sensations were associated with the enhanced cortical hyperexcitability of the migraine sufferers. In our study, we aimed to build on this theory by comparing the neurophysiological activities between regular migraine sufferers and control using electroencephalography (EEG). Using the same research method, we also compared the neural activities between healthy participants who reported having more abnormal visual sensations to those with less. (more…)
