The nervous system not only works to produce thoughts, emotions, and behavior, but also controls important body functions, like breathing.
Studying the nervous system advances understanding of our basic biology and body function. Knowing how things typically work can help shed light on what may happen when there are problems. It can help researchers find ways to prevent or treat problems that affect the brain, nervous system, and body.
In addition to examining the normal development and activity of the nervous system, neuroscience studies diseases, disorders, and injuries that affect parts of the nervous system, how it develops, and how well it functions.
