From one-celled paramecium to giant blue whales, we all have internal clocks that regulate the rhythms we live by. In The Living Clock, John Palmer, one of the world's leading authorities on these rhythms, takes us on a tour of this broad and multifaceted subject, examining everything from glowing fruit flies to the best cures for jet lag. Palmer has a wonderful sense of humor and an eye for the startling fact. We learn that fiddler crabs--in a lab where there are no time nor tide cues--remain active when low tide would occur and motionless during high tide, the same pattern they follow in their natural habitat. (In fact, you can remove a crab's leg and the leg will keep a tidal rhythm as long as it's kept alive.) Moreover, humans are subject to more than one hundred biological rhythms. Mental acuity peaks in the afternoon, for instance, and our blood pressure peaks at seven in the morning (when most heart attacks occur). The time of day you take medication can affect how well it works. And Palmer shows that when our clocks are thrown off kilter, trouble follows, especially for rotating shift workers--the Bhopal spill, the Chernobyl reactor explosion, and the Three Mile Island accident all happened when new crews began early-hour shifts. No one has discovered exactly how our internal clocks work--Palmer says a Nobel Prize awaits that lucky scientist--but they are no less fascinating for their inexplicable nature. Frequently amusing and always eye-opening, The Living Clock is a treat for everyone curious about the nature of life as well as anyone planning a long jet flight.

Circadian rhythms influence most of our life activities, notably getting up and going to sleep every day. This new edition of Circadian Physiology delves into the mechanisms surrounding how these rhythms work, the physiology and biology behind them, and the latest research on this cutting-edge field. The book also discusses a wide variety of practical topics including the prevention of jet lag, management of shift work, sleep disorders, depression, and the optimal times for physical and intellectual activities. To facilitate its use as a textbook, the book contains summaries, suggestions for further reading, links to pertinent websites, and exercises at the end of each chapter. It also includes software for data analysis, tutorials, and simulation programs discussed throughout the text. In addition, more than a thousand references have been added, resulting in a total of more than 6000 references. The text has been thoroughly updated as a result of major advances in recent years. This edition adds discussion on the anatomical and physiological characterization of photoresponsive ganglionic cells in the mammalian retina, molecular circadian clocks in cells of multiple organs other than the hypothalamus and the pineal gland, and advances in the understanding of post-translational mechanisms in the operation of the molecular clock.

Dealing with dynamics of processes that repeat themselves regularly, this revised and updated edition extends the thread from 1980 to the present day, concentrating on areas of interest where there will be much activity in the future. This involves going through spatial biochemical, electrophysiological, and organismic dynamical systems and patterns that were discovered by pursuing the theme of phase singularities introduced in the original book. In particular the work on excitability in cell membranes will be thoroughly updated as will the references throughout the book.

This cultural, historical, and scientific exploration of sleeplessness by Eluned Summers-Bremner begins with the literature of ancient times, and finds its sufferers in prominent texts such as the Iliad, the Odyssey, the Mesopotamian epic Gilgamesh, and the Bible. Moving to Romantic and Gothic literature, she shows how sleeplessness continued to play a large role as the advent of street lighting in the nineteenth century inspired the fantastical blurring of daytime reality and night visions and authors connected insomnia to the ephemeral worlds of nightmares and the sublime. Meanwhile, throughout the ages insomnia has been variously categorized by the medical community as a manifestation of a deeper psychological or physical malady. Today’s medical solutions tend to involve prescription drugs—but, as Insomnia reveals, important questions linger about the role of the pharmaceutical industry and the effectiveness of such treatments. “Summers-Bremner’s account of literary usages of insomnia, from Gilgamesh to Garcia Márquez, is a rich one, sufficient to make the case that insomnia is a recurrent theme in Western culture.”––Wall Street Journal “A whimsical tour of the history of how different cultures have viewed not only insomnia but also the night itself, sleep, dreams, darkness, and activities that occur in the dark.”—New England Journal of Medicine “Summers-Bremner’s excellent account of insomnia shows that the consideration of our waking moments is indicative of the changing ways we think about life.”—Financial Times Magazine

The goal of the applied memory volume is to highlight many interesting and creative applications of basic memory phenomena that are underrepresented, or even unrepresented, in the literature. Authors were charged with the task of reviewing relevant basic and applied research and offering new empirical investigations into the applications of these benchmark phenomena. To this end, Applied Memory, consists of 17 chapters that explore the influences of generation, irrelevant speech, verbal overshadowing, isolation, part-set cuing, reminiscence, hyperemnesia, placebos, mental state, metamemory knowledge, flashbulb events, and traumatic events on memory in everyday settings, as well as applications of source memory, social memory, involuntary autobiographical memory, dream memory, and strategic memory regulation. The volume is designed as a resource for basic and applied memory researchers and as a supplementary text in graduate or upper-level undergraduate courses in cognitive psychology, human memory, or applied psychology.

An Introduction to Biological Rhythms provides an introduction to the subject of biological rhythms. The opening chapters present an overview of biological rhythms, their properties, and clock control, followed by a survey of rhythms in plants and animals. The subsequent chapters cover tidal rhythms and human rhythms; sun-compass, star-compass, and moon compass orientation of animals; the clock control of plant and animal photoperiodism; evidence for external timing of biological clocks; and models and mechanisms for endogenous timekeeping. The book also includes biographical sketches of Dr. Frank A. Brown, Jr., Morrison Professor of Biology at Northwestern University; and Dr. Leland N. Edmunds, Jr., Professor and Head of the Division of Biological Sciences at the Stony Brook campus of the State University of New York. This book is meant for the inquiring student seeking an introduction to the subject and for busy biologists in other fields who want to get a ""feel"" for the subject. It can also serve as a basic textbook for the existing biorhythms courses and act as a seed for the inauguration of new courses.

Popular science at its most exciting: the breaking new world of chronobiology - understanding the rhythm of life in humans and all plants and animals. The entire natural world is full of rhythms. The early bird catches the worm -and migrates to an internal calendar. Dormice hibernate away the winter. Plants open and close their flowers at the same hour each day. Bees search out nectar-rich flowers day after day. There are cicadas that can breed for only two weeks every 17 years. And in humans: why are people who work anti-social shifts more illness prone and die younger? What is jet-lag and can anything help? Why do teenagers refuse to get up in the morning, and are the rest of us really 'larks' or 'owls'? Why are most people born (and die) between 3am-5am? And should patients be given medicines (and operations) at set times of day, because the body reacts so differently in the morning, evening and at night? The answers lie in our biological clocks the mechanisms which give order to all living things. They impose a structure that enables us to change our behaviour in relation to the time of day, month or year. They are reset at sunrise and sunset each day to link astronomical time with an organism's internal time.
