Altered amygdala effective connectivity in migraine without aura: evidence from resting‐state fMRI with Granger causality analysis
Abstract Background Granger causality analysis (GCA) has been used to investigate the pathophysiology of migraine. Amygdala plays a key role in pain modulation of migraine attack. However, the detailed neuromechanism remained to be elucidated. We applied GCA to explore the amygdala-based directional...
