<p/><br></br><p><b> About the Book </b></p></br></br>An argument that health is <i>optimal responsiveness</i> and is often best treated at the system level.<p/><br></br><p><b> Book Synopsis </b></p></br></br><b>An argument that health is <i>optimal responsiveness</i> and is often best treated at the system level.</b><p>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: <i>allostasis</i> (coined by Sterling and Joseph Eyer in the 1980s), whereby the brain anticipates needs and efficiently mobilizes supplies to prevent errors.</p><p>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.</p><p>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 <i>optimal responsiveness</i>, many significant conditions are best treated at the system level.<br></p>
