Weighing just three pounds and encompassing some 100 billion neurons, the brain is the most complex organ in the human body. It and the spinal cord supervise all physical operations. And yet it has proved to be a most elusive organ, hiding the inner workings of the mind, which defines and creates our unique personalities, intellect and consciousness.
During the 1990s--dubbed the "decade of the brain" by presidential decree--scientists unraveled more about the brain's intricate, interconnected cascade of electrical impulses and chemical processes than would ever have seemed possible to many psychologists and neuroscientists just a few decades ago. These discoveries, which are proceeding at a rapid pace, could revolutionize treatments of various brain disorders.
The latest developments in these areas and more are addressed in this special edition from Scientific American. The Hidden Mind brings together and updates firsthand reports from some of the finest minds exploring the brain today. We welcome you to join us as we continue the age-old quest to understand our minds and ourselves. --the Editors
