The altered Granger causality connection among pain-related brain networks in migraine

Numerous fMRI studies have confirmed functional abnormalities in resting-state brain networks in migraine patients. However, few studies focusing on causal relationships of pain-related brain networks in migraine have been conducted. This study aims to explore the difference of Granger causality connection among pain-related brain networks in migraine without aura (MWoA) patients. Twenty two MWoA patients and 17 matched healthy subjects were...
