Cognitive science is most simply defined as the scientific study either of mind or of intelligence. It is an interdisciplinary study drawing from relevant fields including psychology, philosophy, neuroscience, linguistics, anthropology, computer science, biology, and physics. There are several approaches to the study of cognitive science. These approaches may be classified broadly as symbolic, connectionist, and dynamic systems. Symbolic -- holds that cognition can be explained using operations on symbols, by means of explicit computational theories and models of mental (but not brain) processes analogous to the workings of a digital computer. Connectionist (subsymbolic) -- holds that cognition can only be modelled and explained by using artificial neural networks on the level of physical brain properties.
Miao-Kun Sun, Ph.D. obtained his Ph.D. at the Department of Pharmacology, University of Virginia, in 1986, and continued postdoctoral research at the same department for two more years. After a brief research period (one year) at the Department of Physiology, Royal Free Hospital School of Medicine, University College of London, he accepted a faculty position at Department of Neurology and Neuroscience, Cornell University Medical College in New York in 1990. His current position is Professor at Blanchette Rockefeller Neurosciences Institute (holding the same position since 2000).
