This book was released on 2020-01-09 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of a new tool, analytic device, or approach frequently facilitates rapid growth in scientific understanding, although the process is seldom linear. The study of heart rate variability (HRV) defined as the extent to which beat-to-beat variation in heart rate varies, is a rapidly maturing paradigm that integrates health and wellness observations across a wide variety of biomedical and psychosocial phenomena and illustrates this nonlinear path of development. The utility of HRV as an analytic and interventive technique goes far beyond its original application as a robust predictor of sudden cardiac death. This Research Topic aims to provide a conceptual framework to use in exploring the utility of HRV as a robust parameter of health status, using a broad and inclusive definition of ‘health’ and ‘well-being’. From the broadest perspective, current biomedical science emerged from shamanistic and religious healing practices and empirically observed interventions made as humans emerged from other hominins. The exponential growth of physics, chemistry and biology provided scientific support for the model emphasizing pathology and disorders. Even before the momentous discovery of germ theory, sanitation and other preventive strategies brought about great declines in mortality and morbidity. The revolution that is currently expanding the biomedical model is an integrative approach that includes the wide variety of non-physio/chemical factors that contribute to health. In the integrative approach, health is understood to be more than the absence of disease and emphasis is placed on optimal overall functioning, within the ecological niche occupied by the organism. This approach also includes not just interventive techniques and procedures, but also those social and cultural structures that provide access to safe and effective caring for sufferers. Beyond the typical drug and surgical interventions - which many identify with the Western biomedical model that currently enjoys an unstable hegemony - such factors also include cognitive-behavioral, social and cultural practices such as have been shown to be major contributors to the prevention and treatment of disease and the promotion of health and optimal functioning. This Integrative Model of Health and Well-being also derives additional conceptual power by recognizing the role played by evolutionary processes in which conserved, adaptive human traits and response tendencies are not congruent with current industrial and postindustrial global environmental demands and characteristics. This mismatch contributes to an increasing incidence of chronic conditions related to lifestyle and health behavior. Such a comprehensive model will make possible a truly personalized approach to health and well-being, including and going far beyond the current emphasis on genomic analysis, which has promised more that it has currently delivered. HRV offers an inexpensive and easily obtained measure of neurovisceral functioning which has been found to relate to the occurrence and severity of numerous physical disease states, as well as many cognitive-behavioral health disorders. This use of the term neurovisceral refers to the relationships between the nervous system and the viscera, providing a more focused and specific conceptual alternative to the now nearly archaic “mind-body” distinction. This awareness has led to the recent and growing use of HRV as a health biomarker or health status measure of neurovisceral functioning. It facilitates studying the complex two way interaction between the central nervous system and other key systems such as the cardiac, gastroenterological, pulmonary and immune systems. The utility of HRV as a broad spectrum health indicator with possible application both clinically and to population health has only begun to be explored. Interventions based on HRV have been demonstrated to be effective evidence-based interventions, with HRV biofeedback treatment for PTSD representing an empirically supported modality for this complex and highly visible affliction. As an integral measure of stress, HRV can be used to objectively assess the functioning of the central, enteric and cardiac nervous systems, all of which are largely mediated by the vagal nervous complex. HRV has also been found to be a measure of central neurobiological concepts such as executive functioning and cognitive load. The relatively simple and inexpensive acquisition of HRV data and its ease of network transmission and analysis make possible a promising digital epidemiology which can facilitate objective population health studies, as well as web based clinical applications. An intriguing example is the use of HRV data obtained at motor vehicle crash sites in decision support regarding life flight evacuations to improve triage to critical care facilities. This Research Topic critically addresses the issues of appropriate scientific and analytic methods to capture the concept of the Integrative Health and Well-being Model. The true nature of this approach can be appreciated only by using both traditional linear quantitative statistics and nonlinear systems dynamics metrics, which tend to be qualitative. The Research Topic also provides support for further development of new and robust methods for evaluating the safety and effectiveness of interventions and practices, going beyond the sometimes tepid and misleading “gold standard” randomized controlled clinical trial.

Download or read book Extremes written by Kevin Fong and published by Hachette UK. This book was released on 2013-03-14 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: In anaesthetist Dr Kevin Fong's television programmes he has often demonstrated the impact of extremes on the human body by using his own body as a 'guinea pig'. So Dr Fong is well placed to share his experience of the sheer audacity of medical practice at extreme physiological limits, where human life is balanced on a knife edge. Through gripping accounts of extraordinary events and pioneering medicine, Dr Fong explores how our body responds when tested by the extremes of heat and cold, vacuum and altitude, age and disease. He shows how science, technology and medicine have taken what was once lethal in the world and made it survivable. This is not only a book about medicine, but also about exploration in its broadest sense - and about how, by probing the very limits of our biology, we may ultimately return with a better appreciation of how our bodies work, of what life is, and what it means to be human.

This book was released on 2015-04-14 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research topic focuses on epigenetic components of PTSD. Epigenetic mechanisms are a class of molecular mechanisms by which environmental influences, including stress, can interact with the genome to have long-term consequences for brain plasticity and behavior. Articles herein include empirical reports and reviews that link stress and trauma with epigenetic alterations in humans and animal models of early- or later-life stress. Themes present throughout the collection include: DNA methylation is a useful biomarker of stress and treatment outcome in humans; epigenetic programming of stress-sensitive physiological systems early in development confers an enhanced risk on disease development upon re-exposure to trauma or stress; and, long-lived fear memories are associated with epigenetic alterations in fear memory and extinction brain circuitry.

Download or read book Neuroscience of Prejudice and Intergroup Relations written by Belle Derks and published by Psychology Press. This book was released on 2013-06-19 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Psychological research on the origins and consequences of prejudice, discrimination, and stereotyping has moved into previously uncharted directions through the introduction of neuroscientific measures. Psychologists can now address issues that are difficult to examine with traditional methodologies and monitor motivational and emotional as they develop during ongoing intergroup interactions, thus enabling the empirical investigation of the fundamental biological bases of prejudice. However, several very promising strands of research have largely developed independently of each other. By bringing together the work of leading prejudice researchers from across the world who have begun to study this field with different neuroscientific tools, this volume provides the first integrated view on the specific drawbacks and benefits of each type of measure, illuminates how standard paradigms in research on prejudice and intergroup relations can be adapted for the use of neuroscientific methods, and illustrates how different methodologies can complement each other and be combined to advance current insights into the nature of prejudice. This cutting-edge volume will be of interest to advanced undergraduates, graduates, and researchers students who study prejudice, intergroup relations, and social neuroscience.

Download or read book Communicating Social Justice in Teacher Education written by Aubrey A. Huber and published by Routledge. This book was released on 2021-11-10 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolving out of ethnographic fieldwork, this text examines how ideas of social justice are articulated and communicated by pre-service teachers and graduate teaching assistants in the US. By positing the concept of "help" as a central tenet of social justice within teacher education, this volume offers a unique performative analysis of how the concept is communicatively constituted in teacher education and training. Using a social justice framework, the book examines the ways in which new teachers contend with their identities as educators, and demonstrates how these communicative performances influence pre-service and new teachers’ perceptions of their role, as well as their responsibility to engage with social justice and critical approaches in the classroom. This text will benefit researchers, academics, and educators in higher education with an interest in teacher education, critical communication studies, and the sociology of education more broadly. Those specifically interested in teacher training, mentoring, and social justice in the classroom will also benefit from this book.

Download or read book Principles of Brain Dynamics written by Mikhail I. Rabinovich and published by MIT Press. This book was released on 2023-12-05 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental and theoretical approaches to global brain dynamics that draw on the latest research in the field. The consideration of time or dynamics is fundamental for all aspects of mental activity—perception, cognition, and emotion—because the main feature of brain activity is the continuous change of the underlying brain states even in a constant environment. The application of nonlinear dynamics to the study of brain activity began to flourish in the 1990s when combined with empirical observations from modern morphological and physiological observations. This book offers perspectives on brain dynamics that draw on the latest advances in research in the field. It includes contributions from both theoreticians and experimentalists, offering an eclectic treatment of fundamental issues. Topics addressed range from experimental and computational approaches to transient brain dynamics to the free-energy principle as a global brain theory. The book concludes with a short but rigorous guide to modern nonlinear dynamics and their application to neural dynamics.
