Hemodynamic Changes Following Visual Stimulation and Breath-holding Provide Evidence for an Uncoupling of Cerebral Blood Flow and Volume from Oxygen Metabolism

Functional neuroimaging is most commonly performed using the blood-oxygenation-level-depend (BOLD) approach, which is sensitive to changes in cerebral blood flow (CBF), cerebral blood volume (CBV), and the cerebral metabolic rate of oxygen (CMRO(2)). However, the precise mechanism by which neuronal...
