Brain and Behavior: A Cognitive Neuroscience Perspective addresses the central aims of cognitive neuroscience, seeking to examine the brain not only by its components but also by their functions. It highlights the principles, discoveries, and remaining mysteries of modern cognitive neuroscience. Brain and Behavior covers a wide swath of territory critical for understanding the brain, from the basics of the nervous system, to sensory and motor systems, sleep, language, memory, emotions and motivation, social cognition, and brain disorders. Throughout the narrative, the authors emphasize the dynamically changing nature of the brain, through the mechanisms of neuroplasticity. Wherever possible, they refer to elements of neuroscience that are encountered in everyday life. Key points and concepts are illustrated using case studies of rare but illuminating brain disorders. Brain and Behavior pulls together the best current knowledge about the brain while acknowledging current areas of ignorance and pointing students towards the most promising directions for future research.
