Why the study?
Neurovascular coupling studies commonly assess the mean cerebral hemodynamic response with little consideration for diastole, systole, and biological sex.
Assessing neurovascular coupling across the cardiac cycle rather than relying solely on mean values reveals significant systolic activation differences and diastolic sex-specific differences.
Neurovascular coupling (NVC) studies commonly assess the mean cerebral hemodynamic response with little consideration for diastole, systole, and biological sex. Greater total activation expressed as the area under the curve was seen within systole compared with mean and diastole. Resting cerebral blood velocity sex differences were more prevalent during diastole when the cerebrovasculature was pressure-passive. Future studies should assess the NVC response across the cardiac cycle as it may help delineate the underlying pathophysiology of various clinical populations.
