Blood oxygen level dependent functional magnetic resonance imaging (BOLD
fMRI) scans show active regions of the brain. It has been assumed that the
excess of oxygen detected in an active region is brought there by increased
blood flow.

Has this assumption of increased blood flow been proved correct by
experiment?
