Book Description
How the cerebral cortex operates near a critical phase transition point for optimum performance. Individual neurons have limited computational powers, but when they work together, it is almost like magic. Firing synchronously and then breaking off to improvise by themselves, they can be paradoxically both independent and interdependent. This happens near the critical point: when neurons are poised between a phase where activity is damped and a phase where it is amplified, where information processing is optimized, and complex emergent activity patterns arise. The claim that neurons in the cortex work best when they operate near the critical point is known as the criticality hypothesis. In this book John Beggs—one of the pioneers of this hypothesis—offers an introduction to the critical point and its relevance to the brain. Drawing on recent experimental evidence, Beggs first explains the main ideas underlying the criticality hypotheses and emergent phenomena. He then discusses the critical point and its two main consequences—first, scale-free properties that confer optimum information processing; and second, universality, or the idea that complex emergent phenomena, like that seen near the critical point, can be explained by relatively simple models that are applicable across species and scale. Finally, Beggs considers future directions for the field, including research on homeostatic regulation, quasicriticality, and the expansion of the cortex and intelligence. An appendix provides technical material; many chapters include exercises that use freely available code and data sets.

Book Description
The Arm(R) Cortex(R)-M processors are already one of the most popular choices for loT and embedded applications. With Arm Flexible Access and DesignStart(TM), accessing Arm Cortex-M processor IP is fast, affordable, and easy. This book introduces all the key topics that system-on-chip (SoC) and FPGA designers need to know when integrating a Cortex-M processor into their design, including bus protocols, bus interconnect, and peripheral designs. Joseph Yiu is a distinguished Arm engineer who began designing SoCs back in 2000 and has been a leader in this field for nearly twenty years. Joseph's book takes an expert look at what SoC designers need to know when incorporating Cortex-M processors into their systems. He discusses the on-chip bus protocol specifications (AMBA, AHB, and APB), used by Arm processors and a wide range of on-chip digital components such as memory interfaces, peripherals, and debug components. Software development and advanced design considerations are also covered. The journey concludes with 'Putting the system together', a designer's eye view of a simple microcontroller-like design based on the Cortex-M3 processor (DesignStart) that uses the components that you will have learned to create.

Book Description
“A must-read for the cerebral sports fan . . . like Moneyball except nerdier. Much nerdier.” —Sports Illustrated Why couldn’t Michael Jordan, master athlete that he was, crush a baseball? Why can’t modern robotics come close to replicating the dexterity of a five-year-old? Why do great quarterbacks always seem to know where their receivers are? On a quest to discover what actually drives human movement and its spectacular potential, journalist, sports writer, and fan Zach Schonbrun interviewed experts on motor control around the world. The trail begins with the groundbreaking work of two neuroscientists in Major League Baseball who are upending the traditional ways scouts evaluate the speed with which great players read a pitch. Across all sports, new theories and revolutionary technology are revealing how the brain’s motor control system works in extraordinarily talented athletes like Stephen Curry, Tom Brady, Serena Williams, and Lionel Messi; as well as musical virtuosos, dancers, rock climbers, race-car drivers, and more. Whether it is timing a 95 mph fastball or reaching for a coffee mug, movement requires a complex suite of computations that many take for granted—until they read The Performance Cortex. Zach Schonbrun ushers in a new way of thinking about the athletic gifts we marvel over and seek to develop in our own lives. It’s not about the million-dollar arm anymore. It’s about the million-dollar brain.

Book Description
This is the fourth edition of the undisputed classic on the prefrontal cortex, the principal "executive" structure of the brain. Because of its role in such cognitive functions as working memory, planning, and decision-making, the prefrontal cortex is critically involved in the organization of behavior, language, and reasoning. Prefrontal dysfunction lies at the foundation of several psychotic and neurodegenerative disorders, including schizophrenia and dementia. - Written by an award-winning author who discovered "memory cells"-the physiological substrate of working memory - Provides an in-depth examination of the contributions of every relevant methodology, from comparative anatomy to modern imaging - Well-referenced with more than 2000 references

Book Description
This volume of Cerebral Cortex is dedicated to Sir John Eccles, who was an active member of the advisory board for the series until his death in May 1997. His input as to what topics should be covered in future volumes of this series will be sorely missed. The present volume is concerned with neurodegenerative disorders and age related changes in the structure and function of the cerebral cortex, a topic that has attracted increasing interest as longevity and the number of aged individuals in the population increase. Although much of the research on the neurodegenerative effects of aging has been centered on Alzheimer's disease, most of the aging popu lation will not be afflicted by this disease. They will, however, be affected by the consequences of normal aging, so the first few chapters of this volume are con cerned with that topic. Chapter 1, by Marilyn S. Albert and Mark B. Moss, gives an account of the cognitive changes that accompany normal human aging. Chapter 2, by Mark B.

Book Description
This volume is devoted to mathematical models of the cortex. Computational models of individual neurons and ensembles of neurons are increasingly used in research on cortical organization and function. This is, in part, because of the now ubiquitous presence of powerful and affordable computers. The volume begins with a short history of models of cortical neurons and circuitry that introduces the principal modeling styles. An attempt has been made throughout the volume to make it accessible to readers with minimal mathematical backgrounds.

Book Description
These published proceedings of a Neurosciences Research Program Colloquium do not deal exhaustively with particular cortical issues—rather, they convey the highlights of the topic, beginning with a series of presentations on the ontogenetic and morphogenetic development of the cerebral cortex followed by a systematic view of the remarkable explosion during the last decade of our knowledge of the cellular organization and connectively of the cortex. All of the topics in the book are put into perspective in an opening keynote by W. Maxwell Cowan. He there observes that theoretical constructs (or the lack of them) are the weakest aspect of neurobiology at the moment. Thus the book's final section (with contributions by three Nobel laureates—Francis Crick, Gerald Edelman, and Leon Cooper—among others) is a meaningful new effort toward redressing the balance.
