Book Description
This book aims at presenting biologists and clinicians with a compact description of the physiological manifestations of sleep that are significant from the viewpoint of the principle of homeostasis. In the jargon of the physiological literature, the word ?homeostasis?, introduced by W.B. Cannon (1926), refers to the existence of a constant state of extracellular body fluids with regard to their physical and chemical properties. Since normal cell function depends on the constancy of such fluids, in multicellular animals there are many regulatory mechanisms under the control of the central nervous system that act to maintain the constancy of the internal environment.The experimental study of homeostasis in wakefulness already revealed the nature and complexity of the underlying physiological mechanisms. Many of these regulatory mechanisms trigger compensatory changes according to the principle of negative feedback. In contrast, the control of homeostasis across sleep states is still an issue under debate concerning its physiological persistence and significance. The author's aim is to find the specific mechanistic proofs of the actual consistency or inconsistency of the principle in different states of sleep. In this respect, there are several interacting physiological functions that ought to be examined across the sleep states. The selection of the most significant experimental data is carried out with a view to present a simple but not simplistic approach to the issue.The book brings forth the evidence that the systemic homeostatic regulation of many physiological variables underlying cellular life is not active in a particular state of the ultradian sleep cycle in mammals. It also shows the theoretical and functional importance of the principle of homeostasis, as a criterion of the systemic characterisation of the integrative control of physiological functions by the central nervous system during sleep in mammals.

Book Description
Sleep is one of the key underpinnings of human health yet sleep deprivation and impaired sleep are rampant in modern life. Sleep and wake are a true yin yang phenomenon, each affecting the other and together forming a harmonious whole. Healthy sleep is a whole-body process impacted by circadian rhythm, daily activities, and emotional well-being, among others. When properly aligned, these work in concert to produce restorative and refreshing sleep. When not in balance, however, sleep disorders result. Yet too often, the conventional medical approach to treatment of sleep disorders is compartmentalized, failing to recognize all of the complex interactions that are involved. The first book in its field, Integrative Sleep Medicine offers a true comprehensive approach to sleep and sleep disorders by delineating the many factors that interplay into healthy sleep. Health care practitioners can learn how to better manage their patients with sleep disorders by integrating complementary and conventional approaches. Using an evidence-based approach throughout, this book describes the basics of normal sleep, then delves into the foundations of integrative sleep medicine, including the circadian rhythm, mind-body sleep connection, light, dreaming, the gastrointestinal system, and botanicals and supplements. Specific sleep issues and disorders are then addressed from an integrative perspective, including insomnia, obstructive sleep apnea, sleep related movement disorders, and parasomnias.

Book Description
This comprehensive book addresses all elements of the autonomic nervous system (ANS) and sleep interaction, as well as ANS alterations in sleep and how these impact primary and comorbid sleep dysfunction. It meets the market need for a comprehensive text that deals with ANS changes in sleep and how these impact various neurological, medical, and primary sleep disorders. Organized into three parts, the book begins with a review of the foundational bodily systems that participate in coordination of ANS activity with other homeostatic responses such as respiration, cardiovascular reflexes, and responses to stress. Part two then examines methods of laboratory evaluation and the “why, when, how” of interpreting heart rate variability in sleep. To conclude, the final section of the book broadly covers the many clinical aspects of ANS, including insomnia, restless leg syndrome, sleep apnea, sleep related epilepsy, and acute autonomic neuropathy. Autonomic Nervous System and Sleep enhances the reader's understanding of the pathophysiology of various disorders, and explains how to apply this profound understanding is important to new lines of therapy to improve morbidity.

Book Description
This practical text provides knowledge of the basic neuroscience of sleep and sleep disorders as they interrelate with various neurologic conditions. Chapters in the first section cover neural networks involved in normal sleep processes, including dreams and memory. Also discussed are how these neural networks interact in various sleep stages and sleep disorders, such as sleep related movement disorders. The book's second section explores the pathophysiology of sleep disorders in the spectrum of neurologic conditions in both adults and children. This includes sleep changes in patients with dementia, seizures, headaches, and stroke, and other common neurologic disorders. Sleep Neurology fills an important gap in the sleep medicine literature by providing the underpinnings of sleep disorders and will be of great value to students, residents, and clinicians.

Book Description
The Auditory System in Sleep, Second Edition presents a view of a sensory system working in a different state, that of the sleeping brain. This updated edition contains new chapters on topics such as implanted deaf patients and sleep and tinnitus treatments. It is written for basic auditory system and sleep researchers, as well as practitioners and clinicians in the Auditory/Sensory Neurosciences and Sleep Medicine. As the auditory system is always "open, thus receiving information from the environment and the body itself (conscious and unconscious data), the incoming sensory information may alter sleep and waking physiology, and conversely, the sleeping brain. This book draws information from evoked potentials, fMRI, PET, SPECT, lesions, and more. - Contains new chapters on topics such as implanted deaf patients and sleep and tinnitus treatments during sleep - Written for researchers and clinical practitioners in the auditory sciences, sleep medicine and sensory neuroscience

Book Description
The dissertation investigates the scientific and business factors that have resulted in air-conditioning being a major contributor to climate-change. With his architectural background, the author demonstrates how a design methodology, not commonly adopted in scientific studies, may actually be a suitable way of dealing with a complex problem: the 'business as usual' scenario involving building science, sociological values and consumer behavior. Using his innovations as case studies, the author shows how good ideas cannot be evaluated on scientific merit alone and demonstrates why commercialization may have a pivotal role in deployment of research-based technology. He advances the theory of personalized thermal comfort which can potentially resolve the air-conditioning conundrum.

Book Description
This book focuses on a prototype of creative causal processes termed BIOS and how the concept can be applied to the physical world, in medicine and in social science. This book presents methods for identifying creative features in empirical data; studies showing biotic patterns in physical, biological, and economic processes; mathematical models of bipolar (positive and negative) feedback that generate biotic patterns. These studies support the hypothesis that natural processes are creative (not determined) and causal (not random) and that bipolar feedback plays a major role in their evolution. Simple processes precede, coexist, constitute and surround the complex systems they generate (priority of the simple). In turn, complex processes feedback and transform simpler ones (supremacy of the complex).
