This book presents an emerging new vision of the brain, which is essentially expressed in computational terms, for non-experts. As such, it presents the fundamental concepts of neuroscience in simple language, without overwhelming non-biologists with excessive biological jargon. In addition, the book presents a novel computational perspective on the brain for biologists, without resorting to complex mathematical equations. It addresses a comprehensive range of topics, starting with the history of neuroscience, the function of the individual neuron, the various kinds of neural network models that can explain diverse neural phenomena, sensory-motor function, language, emotions, and concluding with the latest theories on consciousness. The book offers readers a panoramic introduction to the "new brain" and a valuable resource for interdisciplinary researchers looking to gatecrash the world of neuroscience. It presents neuroscience from a computational perspective so that the subject can be easily understood by non-biologists and addresses the underlying neural principles without the use of mathematics so that biology students can understand the concepts. It does not merely present a descriptive account of the brain, as many classical biology books do. Written in an easy, engaging style that makes reading a pleasure and rewarding experience, it equips students with the conceptual tools necessary to prepare them for a research career in neuroscience.
