Flow-metabolism coupling in human visual, motor, and supplementary motor areas assessed by magnetic resonance imaging.

Abstract:

Combined blood oxygenation level-dependent (BOLD) and arterial spin labeling (ASL) functional MRI (fMRI) was performed for simultaneous investigation of neurovascular coupling in the primary visual cortex (PVC), primary motor cortex (PMC), and supplementary motor area (SMA). The hypercapnia-calibrated method was employed to estimate the fractional change in cerebral metabolic rate of oxygen consumption (CMR(O2)) using both a group-average and a per-subject calibration. The group-averaged cali...
