The brain is the command center of living creatures including human. Although being a biological unit composed of billions of nerve cells (neurons) and nerve fibers, the brain is often called microcosmos because it processes vast quantities of information and controls higher order mental functions such as recognition, memory, thought, language, emotion, and consciousness through its extremely complex network of neurons. Brain Science or Neuroscience, the study of nervous system, is indeed referred to the ultimate frontier of the science in the 21st Century.

The ultimate goal of Brain Science, as unexplored as the whole universe, is to elucidate the identity of mankind and to understand what is life. Especially, in today's information-oriented, intellectual, and aging society, understanding of nervous system will emancipate us from fears of neural diseases and enable us to develop brain-style systems and network for information processing. Altogether, progress in Brain Science will provide a key knowledge leading to accommodation of human life and to forefront technology in the future. To be in the leading edge, large-scale research programs on Brain Science are under way in the United States as well as in Europe. The United States declared the "Decade of the Brain" in 1990. In 1991 Europe established the "Europe Decade of the Brain" Committee and has stimulated research activity. Following this trend, Korea formulated "The Law of the Promotion of Brain Science Research" in June 1998 and the government-supported brain research program such as "BrainTech" are now proceeding.

In this context, "Interdisciplinary Program in Brain Science" was formed in the Seoul National University at the end of 1998. The College of Natural Sciences is in charge of running the program. It is an interdepartmental program that links basic and clinical faculties throughout the Seoul National University and aims to provide human resources of high quality in the field of Brain Science by training highly qualified students in M.S. and Ph.D. courses to cover the basic principles of the brain and nervous system as well as biomedical and engineering applications.

The program consists of six core courses such as "principles of neuroscience", "cellular neurophysiology", "molecular neurobiology, "systems neuroscience", "behavioral neuroscience", and "computational neuroscience". These courses, balanced in basic and applied sciences, include principles of neurosciences in molecular, cellular, and systems levels and also computer science and engineering such as neural network. The core courses will be lectured by faculty in the Interdisciplinary Program in Brain Science and other related courses" will be given by colleges where the graduate student's academic adviser is assigned. A student may choose to carry out a dissertation research in any of the laboratories within the program.

Because demand in expert neuroscientists is expected to rise rapidly in the future information-oriented society of 21st Century, the graduates from this program are expected to play leading roles in the academic and research sectors, and industrial field as well .
