This study shows that unilateral carotid artery stenosis reduces interhemispheric BOLD coherence at ~0.1 Hz, especially in watershed areas, suggesting impaired vasomotor activity affects resting-state functional connectivity.

This study investigates brain activity changes during migraine cycles, finding cyclic perfusion in the limbic circuit and hypothalamic connectivity shifts, suggesting the hypothalamus drives migraine attacks by losing control over the limbic system.
