Functional magnetic resonance imaging (fMRI) represents one of the most advanced and enlightening functional imaging techniques that has ever been developed. The past ten years (1990–2000) of scientific research has been designated the decade of the brain and has led to numerous technological developments and the establishment of fundamental clinical protocols to understand brain functions. The next decade, the beginning of the 21st century, will continue the great momentum of brain research. This is currently one of the most exciting and progressive times of scientific advancement in the field of brain function and the development and application of fMRI are the driving forces
