Neuroscience is the scientific study of the nervous system. Current neuroscience is not only a branch of biology, it involves many others disciplines such as psychology, philosophy, mathematics, medicine, physics, and computer science. Current neuroscience research activities can be roughly categorized into the following major branches, including molecular and cellular neuroscience, developmental neuroscience, neural engineering, neurology, psychiatry, systems neuroscience, behavioral neuroscience, cognitive neuroscience, neuroimaging, neurolinguistics, theoretical neuroscience, and computational neuroscience, etc. Therefore, the term neurobiology is more accurate than neuroscience when refers specifically to the biology of the nervous system.
