MRI Machine


Magnetic resonance imaging (MRI), the most widely used form of brain imaging, uses magnetic fields and radio waves to produce detailed images of the structure and function of the brain.

Functional MRI (fMRI) is a technique that measures the activity of different brain regions as subjects lie inside the MRI scanner. It works by measuring changes in blood flow and blood oxygenation that follow changes in neuronal activity. By comparing the signals obtained as subjects perform different tasks within the scanner, researchers can generate maps that show which parts of the brain are involved in different cognitive processes.
