Correlation analysis between prefrontal oxygenation oscillations and cerebral artery hemodynamics in humans

► Significant correlation was found between prefrontal oscillations and PI in ECA. ► Prefrontal oxygenation oscillations are closely related to the pulsatility of ECA. ► Prefrontal oxygenation oscillations are also related to the flow velocity in MCA. ► Prefrontal oxygenation oscillations reflect partly the vessel stiffness of MCA.
