Brain Facts: A Primer on the Brain and Nervous System
Neuroscientists investigate the molecular and cellular levels of the nervous system; the neuronal systems responsible for sensory and motor function; and the basis of higher order processes, such as cognition and emotion. This research provides the basis for understanding the medical fields that are concerned with treating nervous system disorders. These medical specialties include neurology, neurosurgery, psychiatry and ophthalmology. But the brain is much more complicated than any of these devices, fact scientists confirm almost daily with each new discovery. The extent of the brain's capabilities is unknown, but it is the most complex living structure known in the universe.
