Neuroscience is a scientific discipline that studies the structure, function, development, genetics, biochemistry, physiology, pharmacology, pathology of the nervous system, and psychology. Traditionally it was seen as a branch of biological sciences. However, recently there has been a convergence of interest from other disciplines, including chemistry, computer science, statistics, physics, philosophy, mathematics, and medicine. The scope of neuroscience has now broadened to include any systematic scientific experimental and theoretical investigation of the central and peripheral nervous system of biological organisms. The methodologies employed by neuroscientists have been enormously expanded, from biochemical and genetic analysis of dynamics of individual nerve cells and their molecular constituents to imaging representations of perceptual and motor tasks in the brain.
Furthermore, neuroscience is at the frontier of investigation of the brain and mind. The study of the brain is becoming the cornerstone in understanding how we perceive and interact with the external world and, in particular, how human experience and human biology influence each other. It is likely that the study of the brain will become one of the central intellectual endeavors in the coming decades.
