With over four hundred new citations, Cognitive Neuroscience, Second Edition, embraces the latest findings in this cutting-edge field. A revised chapter two, ''The Cellular and Molecular Basis of Cognition,'' introduces new analysis of the chemical systems that support cognition, outlines the modulation of neuronal transmission during development and disease, and increases coverage of the function of membrane receptors in neurochemistry. An entirely new chapter three, ''Gross and Functional Anatomy of Cognition,'' provides a foundation for working through the functional analysis of cognitive systems in subsequent chapters. The Second Edition also includes extensive coverage of computational modeling, highlighting the ways in which modeling demonstrates the neural mechanisms of cognition.
