Neuroscience, in its broadest definition, is the study of the structure and function of the brain. Specific areas of study within neuroscience include physiology, behavior, biochemistry, development, pharmacology and pathology. Because of the way the brain organizes and processes information and coordinates and controls behavior, any full understanding of how the brain functions must include a variety of approaches and perspectives. Historically, neuroscience developed out of the shared interests of biologists and psychologists, and more recently mathematicians and chemists, to understand how brain, mind, and behavior are related. Not surprisingly, investigators from these disciplines use different approaches in their research on how the brain functions. This synthesis of approaches has created a truly interdisciplinary field of study and has significantly advanced our knowledge of how the brain works.
