CBF/CMRO(2) Coupling Measured with Calibrated-BOLD fMRI: Sources of Bias
The coupling between cerebral blood flow (CBF) and cerebral metabolic rate of oxygen (CMRO(2)) during brain activation can be characterized by an empirical index n, the ratio of fractional CBF changes to fractional CMRO(2) changes. Measurements of n have yielded varying results, and it is not known...
