Synopsis Rheostasis by : Nicholas Mrosovsky

This work offers a comprehensive re-examination and elaboration of homeostasis, a guiding principle in physiology that has received surprisingly little critical evaluation. Among the key topics addressed are questions concerning the competing demands of different regulatory systems within the body and the problem of maintaining equilibrium in such circumstances. The author makes the important point that the body does not always seek constancy of its internal environment, nor does it always react in ways that prevent change. On the contrary, sometimes physiological mechanisms actively promote change. These changes in regulated levels--termed "rheostasis"--are seen as having an adaptive value beyond a simple failure of homeostasis. This book compares and categorizes examples of rheostasis for a variety of physiological variables, and presents what is known about conflicts between different regulatory systems and their role in promoting the occurrence of rheostasis. Among other topics covered are weight loss during hibernation, calcium storage and reproduction, fever, and rates of fat deposition in adults. The work of an outstanding scholar, this integrative study represents a refreshing and essential new approach to one of the basic concepts in physiological science.

Synopsis What Is Health? by : Peter Sterling

An argument that health is optimal responsiveness and is often best treated at the system level. Medical education centers on the venerable “no-fault” concept of homeostasis, whereby local mechanisms impose constancy by correcting errors, and the brain serves mainly for emergencies. Yet, it turns out that most parameters are not constant; moreover, despite the importance of local mechanisms, the brain is definitely in charge. In this book, the eminent neuroscientist Peter Sterling describes a broader concept: allostasis (coined by Sterling and Joseph Eyer in the 1980s), whereby the brain anticipates needs and efficiently mobilizes supplies to prevent errors. Allostasis evolved early, Sterling explains, to optimize energy efficiency, relying heavily on brain circuits that deliver a brief reward for each positive surprise. Modern life so reduces the opportunities for surprise that we are driven to seek it in consumption: bigger burgers, more opioids, and innumerable activities that involve higher carbon emissions. The consequences include addiction, obesity, type 2 diabetes, and climate change. Sterling concludes that solutions must go beyond the merely technical to restore possibilities for daily small rewards and revivify the capacities for egalitarianism that were hard-wired into our nature. Sterling explains that allostasis offers what is not found in any medical textbook: principled definitions of health and disease: health as the capacity for adaptive variation and disease as shrinkage of that capacity. Sterling argues that since health is optimal responsiveness, many significant conditions are best treated at the system level.

Synopsis Missed Information by : David Sarokin

How better information and better access to it improves the quality of our decisions and makes for a more vibrant participatory society. Information is power. It drives commerce, protects nations, and forms the backbone of systems that range from health care to high finance. Yet despite the avalanche of data available in today's information age, neither institutions nor individuals get the information they truly need to make well-informed decisions. Faulty information and sub-optimal decision-making create an imbalance of power that is exaggerated as governments and corporations amass enormous databases on each of us. Who has more power: the government, in possession of uncounted terabytes of data (some of it obtained by cybersnooping), or the ordinary citizen, trying to get in touch with a government agency? In Missed Information, David Sarokin and Jay Schulkin explore information—not information technology, but information itself—as a central part of our lives and institutions. They show that providing better information and better access to it improves the quality of our decisions and makes for a more vibrant participatory society. Sarokin and Schulkin argue that freely flowing information helps systems run more efficiently and that incomplete information does just the opposite. It's easier to comparison shop for microwave ovens than for doctors or hospitals because of information gaps that hinder the entire health-care system. Better information about such social ills as child labor and pollution can help consumers support more sustainable products. The authors examine the opacity of corporate annual reports, the impenetrability of government secrets, and emerging techniques of “information foraging.” The information imbalance of power can be reconfigured, they argue, with greater and more meaningful transparency from government and corporations.

Synopsis Allostasis, Homeostasis, and the Costs of Physiological Adaptation by : Jay Schulkin

The concept of homeostasis, the maintenance of the internal physiological environment of an organism within tolerable limits, is well established in medicine and physiology. In contrast, allostasis is a relatively new idea of 'viability through change'. With allostatic regulation by cephalic involvement, the body adapts to potentially diverse and dangerous situations through the activation of neural, hormonal, or immunological mechanisms. Allostasis explains how regulatory events maintain organismic viability, or not, in diverse contexts with varying set points of bodily needs and competing motivations. This 2005 book introduces the concept of allostasis and sets it alongside traditional views of homeostasis. It addresses basic regulatory systems and examines the behavior of bodily regulation under duress. The basic concepts of physiological homeostasis are integrated with disorders like depression, stress, anxiety and addiction. It will therefore appeal to graduate students, medical students and researchers working in physiology, epidemiology, endocrinology, neuroendocrinology, neuroscience, and psychology.

Synopsis Curt Richter by : Jay Schulkin

In the first half of the twentieth century, psychology was a discipline in search of scientific legitimacy. Debates raged over how much of human and animal behavior is instinctive and how much is learned, and how behavior could be quantified accurately. At the Johns Hopkins University's new Phipps Psychiatric Clinic, Curt P. Richter stood aside from these heated theoretical arguments, choosing instead to apply his data-collection methods, innovative measurement techniques, playful sense of exploration, and consummate surgical skill to laboratory examinations of the biological basis of behavior. From identifying the biological clocks that govern behavior and physiology to observing the self-regulation of nutrient levels by the body, the cyclical nature of some mental illnesses, and the causes of hopelessness, Richter's wide-ranging discoveries not only influenced the burgeoning field of psychobiology and paved the way for later researchers but also often had implications for the treatment of patients in the clinic. At the time of his death in 1988, Richter left behind a massive collection of laboratory data. For this book, Jay Schulkin mined six decades of Richter's archived research data, personal documents, and interviews to flesh out an engaging portrait of a "laboratory artisan" in the context of his work.

Synopsis Good Reasons for Bad Feelings by : Randolph M. Nesse, MD

A founder of the field of evolutionary medicine uses his decades of experience as a psychiatrist to provide a much-needed new framework for making sense of mental illness. Why do I feel bad? There is real power in understanding our bad feelings. With his classic Why We Get Sick, Dr. Randolph Nesse helped to establish the field of evolutionary medicine. Now he returns with a book that transforms our understanding of mental disorders by exploring a fundamentally new question. Instead of asking why certain people suffer from mental illness, Nesse asks why natural selection has left us all with fragile minds. Drawing on revealing stories from his own clinical practice and insights from evolutionary biology, Nesse shows how negative emotions are useful in certain situations, yet can become overwhelming. Anxiety protects us from harm in the face of danger, but false alarms are inevitable. Low moods prevent us from wasting effort in pursuit of unreachable goals, but they often escalate into pathological depression. Other mental disorders, such as addiction and anorexia, result from the mismatch between modern environment and our ancient human past. And there are good evolutionary reasons for sexual disorders and for why genes for schizophrenia persist. Taken together, these and many more insights help to explain the pervasiveness of human suffering, and show us new paths for relieving it by understanding individuals as individuals.
