Functional Magnetic Resonance Imaging
fMRI or functional magnetic resonance imaging, is a relatively young brain activity imaging technology. It works based on detection of the dynamic regulation of blood flow in the brain. Medically, this is termed the haemodynamic response, however it is simply tracking brain activity based on increasing and decreasing demand for oxygen and glucose in the haemoglobin of the blood in the brain.
