Book Description :

In this groundbreaking union of art and science, rocker-turned-neuroscientist Daniel J. Levitin explores the connection between music—its performance, its composition, how we listen to it, why we enjoy it—and the human brain. Taking on prominent thinkers who argue that music is nothing more than an evolutionary accident, Levitin poses that music is fundamental to our species, perhaps even more so than language. Drawing on the latest research and on musical examples ranging from Mozart to Duke Ellington to Van Halen, he reveals: • How composers produce some of the most pleasurable effects of listening to music by exploiting the way our brains make sense of the world • Why we are so emotionally attached to the music we listened to as teenagers, whether it was Fleetwood Mac, U2, or Dr. Dre • That practice, rather than talent, is the driving force behind musical expertise • How those insidious little jingles (called earworms) get stuck in our head A Los Angeles Times Book Award finalist, This Is Your Brain on Music will attract readers of Oliver Sacks and David Byrne, as it is an unprecedented, eye-opening investigation into an obsession at the heart of human nature.

Book Description :

Dementia is the most significant health issue facing our aging population. With no cure to date, there is an urgent need for the development of interventions that can alleviate symptoms of dementia and ensure optimal well-being for people with dementia and their caregivers. There is accumulating evidence that music is a highly effective, non-pharmacological treatment for various symptoms of dementia at all stages of disease progression. In its various forms, music (as a medium for formal therapy or an informal activity) engages widespread brain regions, and in doing so, can promote numerous benefits, including triggering memories, enhancing relationships, affirming a sense of self, facilitating communication, reducing agitation, and alleviating depression and anxiety. This book outlines the current research and understanding of the use of music for people with dementia, from internationally renowned experts in music therapy, music psychology, and clinical neuropsychology.

Book Description :

NEW YORK TIMES BESTSELLER NATIONAL BESTSELLER SHORTLISTED for the 2021 Science Writers and Communicators of Canada Book Award Author of the iconic bestsellers This Is Your Brain on Music and The Organized Mind, Daniel Levitin turns his keen insights to what happens in our brains as we age, why we should think about health span, not life span, and, based on a rigorous analysis of neuroscientific evidence, what you can do to make the most of your seventies, eighties, and nineties today no matter how old you are now. Successful Aging uses research from developmental neuroscience and the psychology of individual differences to show that sixty-plus years is a unique developmental stage that, like infancy or adolescence, has its own demands and distinct advantages. Levitin looks at the science behind what we all can learn from those who age joyously, as well as how to adapt our culture to take full advantage of older people's wisdom and experience. Throughout his exploration of what aging really means, Levitin reveals resilience strategies and practical, cognitive enhancing tricks everyone should do as they age. The book is packed with accessible and discussable takeaways, providing great material for reading groups and media coverage. Successful Aging inspires a powerful new approach to how readers think about our final decades, and it will revolutionize the way we plan for old age as individuals, family members, and citizens within a society where the average life expectancy continues to rise.

Book Description :

The field of social cognitive neuroscience has captured the attention of many researchers during the past ten years. Much of the impetus for this new field came from the development of functional neuroimaging methods that made it possible to unobtrusively measure brain activation over time. Using these methods over the last 30 years has allowed psychologists to move from simple validation questions -- would flashing stimuli activate the visual cortex -- to those about the functional specialization of brain regions-- are there regions in the inferior temporal cortex dedicated to face processing-- to questions that, just a decade ago, would have been considered to be intractable at such a level of analysis. These so-called "intractable" questions are the focus of the chapters in this book, which introduces social cognitive neuroscience research addressing questions of fundamental importance to social psychology: How do we understand and represent other people? How do we represent social groups? How do we regulate our emotions and socially undesirable responses? This book also presents innovative combinations of multiple methodologies, including behavioral experiments, computer modeling, functional Magnetic Resonance Imaging (fMRI) experiments, Event-Related Potential (ERP) experiments, and brain lesion studies. It is divided into four sections. The first three sections present the latest research on, respectively, understanding and representing other people, representing social groups, and the interplay of cognition and emotion in social regulation. In the fourth section, contributors step back and consider a range of novel topics that have emerged in the context of social neuroscience research: understanding social exclusion as pain, deconstructing our moral intuitions, understanding cooperative exchanges with other agents, and the effect of aging on brain function and its implications for well-being. Taken together, these chapters provide a rich introduction to an exciting, rapidly developing and expanding field that promises a richer and deeper understanding of the social mind.

Book Description :

The study of music and the brain can be traced back to the work of Gall in the 18th century, continuing with John Hughlings Jackson, August Knoblauch, Richard Wallaschek, and others. These early researchers were interested in localizing musicality in the brain and learning more about how music is processed in both healthy individuals and those with dysfunctions of various kinds. Since then, the research literature has mushroomed, especially in the latter part of the 20th and early 21st centuries. The Oxford Handbook of Music and the Brain is a groundbreaking compendium of current research on music in the human brain. It brings together an international roster of 54 authors from 13 countries providing an essential guide to this rapidly growing field. The major themes include Music, the Brain, and Cultural Contexts; Music Processing in The Human Brain; Neural Responses to Music; Musicianship and Brain Function; Developmental Issues in Music and the Brain; Music, the Brain, and Health; and the Future. Each chapter offers a thorough review of the current status of research literature as well as an examination of limitations of knowledge and suggestions for future advancement and research efforts. The book is valuable for a broad readership including neuroscientists, musicians, clinicians, researchers and scholars from related fields but also readers with a general interest in the topic.

Book Description :

"The importance of brain imaging for clinical diagnosis and the understanding of basic mechanisms of disease and aging is well-known in medical science. These techniques have been the basis for numerous studies that have striven to better detect neurological disorders and age-related change in the brain." "This book - co-edited by world-renowned Alzheimer's disease researcher and clinician, William Jagust, and world-renowned neurologist and cognitive neuroscientist, Mark D'Esposito - contains chapters from experts in the fields of brain imaging, clinical neuroscience, and cognitive neuroscience who have studied the aging brain. Topics covered include technical factors in brain imaging, pathological basis of age-related structural and functional changes, neurochemistry and genetics of brain imaging in aging, and the use of imaging techniques in diagnosis, longitudinal testing, drug development and testing, and presymptomatic detection. The book is intended to be both a detailed review of the current status of brain imaging and aging and to serve as an introduction to the field for those who may be starting investigations using imaging techniques of PET, structural MRI, and functional MRI. It covers basic science approaches such as using fMRI to probe networks, as well as recent developments such as amyloid imaging and the use of imaging as a biomarker in clinical trials." "The field of brain aging is undergoing rapid expansion because of new techniques such as fMRI and amyloid imaging which have been applied to both basic and clinical problems. Imaging the Aging Brain is a compendium of relevant knowledge and up-to-date analysis. Written by leaders in neurological research and presented in color, this book is as timely as it is thorough." --Book Jacket.

Book Description :

While growing older is inevitable, many of the troubles we associate with aging--including dementia, disability, and an increased dependence on others--are not. The choices we make now can help us to maintain our vitality, a sharp mind, and our independence as we age. Filled with simple, everyday actions we can take to avoid disease, promote vitality, and prevent dementia and late onset Alzheimer's, The Aging Brain is an easy-to-use guide to maintaining brain and body health throughout our lives. Based on solid, up-to-date scientific research, the interventions explained in this book not only prevent progression toward dementia even in those who have already shown mild cognitive impairment, they also reduce disability and depression and keep people living independently longer than those who do not practice these methods. For anyone hoping to slow the aging process, as well as anyone who acts as a caregiver to someone at risk of or already beginning to suffer from dementia and other age-related diseases, this book offers a hopeful, healthy way forward.

Book Description :

Until very recently, our knowledge about the neural basis of cognitive aging was based on two disciplines that had very little contact with each other. Whereas the neuroscience of aging investigated the effects of aging on the brain independently of age-related changes in cognition, the cognitive psychology of aging investigated the effects of aging on cognition independently of age-related changes in the brain. The lack of communication between these two disciplines is currently being addressed by an increasing number of studies that focus on the relationships between cognitive aging and cerebral aging. This rapidly growing body of research has come to constitute a new discipline, which may be called cognitive neuroscience of aging. The goal of Cognitive Neuroscience of Aging is to introduce the reader to this new discipline at a level that is useful to both professionals and students in the domains of cognitive neuroscience, cognitive psychology, neuroscience, neuropsychology, neurology, and other, related areas. This book is divided into four main sections. The first section describes noninvasive measures of cerebral aging, including structural (e.g., volumetric MRI), chemical (e.g., dopamine PET), electrophysiological (e.g., ERPs), and hemodynamic (e.g., fMRI), and discusses how they can be linked to behavioral measures of cognitive aging. The second section reviews evidence for the effects of aging on neural activity during different cognitive functions, including perception and attention, imagery, working memory, long-term memory, and prospective memory. The third section focuses on clinical and applied topics, such as the distinction between healthy aging and Alzheimers disease and the use of cognitive training to ameliorate age-related cognitive decline. The last section describes theories that relate cognitive and cerebral aging, including models accounting for functional neuroimaging evidence and models supported by computer simulations. Taken together, the chapters in this volume provide the first unified and comprehensive overview of the new discipline of cognitive neuroscience of aging.

Physical Activity and the Aging Brain: Effects of Exercise on Neurological Function is a complete guide to the manifold effects of exercise and physical activity on the aging brain. Cognitive decline and motor impairment, onset of diseases and disorders, and even changes in family structure and social settings that occur as we age can all impact activity levels, yet continued physical activity is crucial for successful neurological functioning. This book examines the role that exercise and physical activity play in halting or modulating the deleterious effects of these numerous aging concerns by first examining the current state of research into how exercise manifests physical changes in the brain. It then discuss how physical activity combines with other lifestyle factors to benefit the aging brain, including nutrition, computerized brain training, and social engagement. Most significantly, it also covers how physical activity can serve as therapy to help alleviate the symptoms of various neurological diseases impacting aging populations, with particular emphasis on Alzheimer’s disease and age-related cognitive decline. The book provides broad coverage of the effects of exercise and physical activity on the aging brain, its therapeutic effects, and the many factors that influence the aging process. Presents research scientists with a complete understanding of the role of exercise in healthy brain aging Considers the roles of nutrition, the mind-body connection, and other lifestyle factors Presents a major resource for exercise and physical activity in the neurological health of older adults Provides a synopsis of key ideas associated with the many aspects of physical activity, along with lifestyle factors that can modify neurological diseases and age-related neurological decline

Book Description :

Music impinges upon the body and the brain. As such, it has significant inductive power which relies both on innate dispositions and acquired mechanisms and competencies. The processes are partly autonomous and partly deliberate, and interrelations between several levels of processing are becoming clearer with accumulating new evidence. For instance, recent developments in neuroimaging techniques, have broadened the field by encompassing the study of cortical and subcortical processing of the music. The domain of musical emotions is a typical example with a major focus on the pleasure that can be derived from listening to music. Pleasure, however, is not the only emotion to be induced and the mechanisms behind its elicitation are far from understood. There are also mechanisms related to arousal and activation that are both less differentiated and at the same time more complex than the assumed mechanisms that trigger basic emotions. It is imperative, therefore, to investigate what pleasurable and mood-modifying effects music can have on human beings in real-time listening situations. This e-book is an attempt to answer these questions. Revolving around the specificity of music experience in terms of perception, emotional reactions, and aesthetic assessment, it presents new hypotheses, theoretical claims as well as new empirical data which contribute to a better understanding of the functions of the brain as related to musical experience.

Author : Jim Walsh
Publisher : Voyageur Press

ISBN : 1616739789
Language : En, Es, Fr & De

Book Description :

Formed in a Minneapolis basement in 1979, the Replacements were a notorious rock ’n’ roll circus, renowned for self-sabotage, cartoon shtick, stubborn contrarianism, stage-fright, Dionysian benders, heart-on-sleeve songwriting, and—ultimately—critical and popular acclaim. While rock then and now is lousy with superficial stars and glossy entertainment, the Replacements were as warts-and-all “real” as it got. In the first book to take on the jumble of facts, fictions, and contradictions behind the Replacements, veteran Minneapolis music journalist Jim Walsh distills hundreds of hours of interviews with band members, their friends, families, fellow musicians, and fans into an absorbing oral history worthy of the scruffy quartet that many have branded the most influential band to emerge from the ’80s. Former manager Peter Jesperson, Paul Stark and Dave Ayers of Twin/Tone Records, Bob Mould and Grant Hart of rivals Hüsker Dü, the legendary Curtiss A, Soul Asylum’s Dan Murphy, Lori Barbero of Babes in Toyland, R.E.M.’s Peter Buck, power-pop hero Alex Chilton, Craig Finn of The Hold Steady, and replacement Replacements Slim Dunlap and Steve Foley: all have something to say about the scene that spawned the band. These and dozens of others offer insights into the Replacement’s workings--and the band’s continuing influence more than fifteen years after their breakup. Illustrated with both rarely seen and classic photos, this, finally, is the rollicking story behind the turbulent and celebrated band that came on fast and furious and finally flamed out, chronicled by one eyewitness who was always at the periphery of the storm, and often at its eye. “[T]his consistently engaging and poignant work . . . . [is a] loving, appropriately ramshackle tribute to one of the most beloved rock-and-roll bands of the 1980s. . . . The band's story is an archetype of the joys and pitfalls of underground success.”--Publishers Weekly “The Replacements were superheroes: They rescued a whole planet from ’80s music. Jim Walsh’s loving, engrossing oral history is the book they deserve.”—Nick Hornby, author of High Fidelity
