Fig. 3 — (a) The CBF changes during unilateral clipping and bi-CCA clipping/unclipping (twice) measured by the laser Doppler (top panel) and DCS (bottom panel). (b) The linear regressions of CBF changes measured by the laser Doppler and DCS. The CBF changes measured by the two techniques are highly correlated (R² = 0.94, p < 0.0001). The inset small plot shows a linear regression of the CBFs with sub-data sets during arterial clippings (CBF < 100%).
