MRI Functional Imaging of the Brain (fMRI)

A magnetic resonance functional imaging (fMRI) of the brain is a noninvasive procedure using no radiation and measures brain activity by observing changes in blood oxygenation and flow in response to neural stimulation. A more active part of the brain requires more oxygen, thereby increasing blood flow to that area of the brain.
