The human brain is a highly complex three-pound organ that serves as central command, interpreter of touch, taste, sight, and sound. The brain commands the body’s movements and controls human behavior by sending messages to muscles. Science has learned more about this indispensable organ over the last 10 years than ever before.

Data collected over the last decade has accelerated the pace of research in neurological and behavioral science and the development of new research techniques.
