The second edition of Principles of Frontal Lobe Function is a newly organized, and thoroughly updated, volume divided into 9 different sections, each co-edited by leaders in the specific domain of frontal lobe research. The topic areas include anatomy and neuropharmacology, development, systems and models, fundamental cognitive mechanisms, social behavior, clinical neuropsychology, aging, psychiatric disorders, and rehabilitation. This organization reflects both an increase in our combined knowledge about frontal lobe functioning through new imaging technologies, as well as the expansion of the field as a whole to include new topics such as social neuroscience that were not discussed in the first edition. Principles of Frontal Lobe Function will naturally be of particular interest to researchers and clinicians actively investigating how the frontal lobes operate and to understand dysfunction as a means to design treatment. This new edition will also be a useful resource for anyone involved in a discipline related to brain function, whether it be cognitive neuroscience, behavioral neurology, neuropsychiatry, neuropsychology, or neurorehabilitation.Our knowledge of how the frontal lobes are integrated with functioning in every other region of the brain is also integrating our approach to solving brain-based problems. Authors in this volume represent investigators who are deep-rooted in frontal lobe research. As such, students will be exposed to both the classical and frontier perspectives and will gain significant insight into future research directions of what we believe to be the most fascinating area of the brain.
