Virtual Dictionary


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.

Unlike detection of electrical signals, it can be performed non-invasively with little to no loss of data. However, the results do not track in real-time, with fMRI data sometimes taking as much as a minute to resolve. This delay can cloud results, on all but long term cognitive activity.
