The mystery called the human brain

We have barely scratched the surface of the mystery called the human brain. Modern techniques make it possible to image the brain in action. With MRI scanners, for example, we can obtain movies of blood flow in the brain, which tell us which brain areas are active during specific tasks. Recent decades have brought a wealth of data on brain topography (the layout of functions across the brain). Yet we still do not understand how the brain works. How thoughts can emanate from electrical and chemical events taking place in and between neurons. How decisions are made and how information is stored and transported between and within brain areas. Understanding these basic concepts is not only important from a science perspective, but it is also essential for development of new treatment solutions for brain disorders.
