Work in clinical and laboratory settings has indicated that lack of bright light during the day can compromise mood, accelerate cancer growth, and impair cognition. Even sustained exposure to the equivalent of a child's night light has been shown to have an impact on everything from how well our brains function every day to how well our bodies recover from injury. Professor Randy J. Nelson brings together the most reliable research on the different ways exposure to light at night affects how our bodies function and, ultimately, our health. Each chapter explores the role of light and dark in our bodies' most important regulatory processes.In humans, virtually every aspect of our physiology and behavior is mediated by our internal biological clocks. One feature of modern life that may have negative consequences for our health is exposure to light levels that are not aligned with the 24-hour solar day. Circadian rhythms, the internal biological rhythms of our body's processes, require short wavelength (blue) light early during the day to optimize their temporal regulation. Experiencing light at night or insufficient light during the day can lead to a host of problems such as obesity, major depression, bipolar depressive disorder, seasonal affective disorder, sleep disorders, cancer, heart disease and more. Dark Matters sets out to shine a light on the health and well-being consequences of poor circadian hygiene and provide strategies to offset the negative health effects of disrupted circadian rhythms.

Unchecked aggression and violence take a significant toll on society. Even if we manage to avoid being the direct victim of a violent act, the effects of aggression and violence reach us all: We hear about the mauling of a woman by an aggressive dog, our children are bullied at school, or we deal with impulsive violence while commuting to work or attending a sporting event. Reflecting psychology in general, the dominant roles of learning and environmental influences - both social and nonsocial - have traditionally been prominent in discussions of the etiology of human aggression. Biological factors have not been considered sufficiently important to investigate in the search for ways of dealing with human aggression or violence. With recent advances in pharmacology and genetic manipulation techniques, however, new interest has developed in the biological mechanisms of both non-human and human aggression. Although aggression is certainly a complex social behavior with multiple causes, molecular biological factors should not be overlooked, as they may well lead to interventions that prevent excess aggressive behaviors. The primary goal of this book is to summarize and synthesize recent advances in the biological study of aggression. As most aggressive encounters among human and non-human animals represent a male proclivity, the research in this book describes and discusses studies using the most appropriate murine model: testosterone-dependent offensive inter-male aggression, which is typically measured in resident-intruder or isolation-induced aggression tests. The research also emphasizes various molecules that have been linked to aggression tests. The research also emphasizes various molecules that have been linked to aggression by the latest gene-targeting and pharmacological techniques. Although the evidence continues to point to androgens and serotonin (5-HT) as major hormonal and neurotransmitter factors in aggressive behavior, recent work with GABA, dopamine, vasopressin, and other factors, such as nitric oxide, has revealed significant interactions with the neural circuitry underlying aggression. This book is organized according to levels of analysis. The first section examines the genetic contributions to aggression in species ranging from crustaceans to humans. The section summarizes the involvement of various neurotransmitters and neuromodulators in aggressive behavior. The third section summarizes the influence of hormones on aggression, primarily in humans. All chapters emphasize future directions for research on aggression and reveal important domains that have received comparatively less attention in this literature. Considered together, these chapters provide up-to-date coverage of the biology of aggression by some of the leading authorities currently working in this field. Biology of Aggression will direct future research to continue the recent advances in the pharmacological and genetic approaches to understanding aggression and violence. It promises to be a valuable resource for professional and student researchers in neuroscience, psychiatry, cognitive and developmental psychology, behavioral biology, and veterinary medicine.

This book examines the role of photoperiod (day length) in timing seasonal adaptations in plants, invertebrates, and vertebrates, and is the first to present such a broad perspective on the subject in quite some time. The current literature is distinctly separated among researchers working with these different taxa, resulting in inefficiency and redundancies. The field is poised to make rapid progress in the understanding of seasonal clocks at all levels of analysis, and Photoperiodism brings together experts working in disparate areas to stimulate conversation among investigators from all related disciplines. At the end of the book, the three editors analyze common themes in photoperiod time measurement across taxa, as well as common and dissimilar approaches to the study of photoperiodism, and propose future directions in research on photoperiodic time measurement.

The market-leading text, An Introduction to Behavioral Endocrinology, Sixth Edition provides an updated, integrated presentation of the study of hormone-behavior-brain interactions. Maintaining a comparative approach, the text explores the endocrine mechanisms that have evolved in both human and nonhuman animals to solve common problems in survival and reproduction.The text describes interactions among hormones, brain, and behavior from a historical perspective, emphasizing connections among key theories and tracing the emergence of important hypotheses. The book is organized around the conceptual theme that hormones affect behavior by influencing one or more of three "components" of behaving animals--input mechanisms (such as sensory or perceptual processes), the central processing mechanisms of the nervous system (either directly, or by affecting its development or structure), and output mechanisms (such as effectors or peripheral structures). Despite increased coverage of molecular and cellular approaches, the book strives for accessibility for non-biological science students.An Introduction to Behavioral Endocrinology, Sixth Edition, is appropriate for upper-level undergraduate and graduate courses in psychology, biology, anthropology, or zoology. It contains several important pedagogical features:*Learning objectives are set out at the beginning of each chapter and now include 3 multiple choice questions per objective in the enhanced ebook.*Learning Activity in each chapter (new to this edition)*Key terms are defined in the margins throughout the text.*The text is richly illustrated with color photographs and drawings.*Chapter-end summaries restate important points.*Discussion questions and suggested further readings are also included in each chapter.*The text contains nearly 2,400 references to the literature in behavioral endocrinology.RESOURCESFor StudentsAs with previous editions, the book is accompanied by animations, video, web links, sound files, a complete glossary, and graphics--accessible via Oxford Learning Link--to aid in understanding the material in the text.This edition will also include an enhanced ebook.

Life evolves in a cyclic environment, and to be successful, organisms must adapt not only to their spatial habitat, but also to their temporal habitat. How do plants and animals determine the time of year so they can anticipate seasonal changes in their habitats? In most cases, day length, or photoperiod, acts as the principal external cue for determining seasonal activity. For organisms not living at the bottom of the ocean or deep in a cave, day follows night, and the length of the day changes predictably throughout the year. These changes in photoperiod provide the most accurate signal for predicting upcoming seasonal conditions. Measuring day length allows plants and animals to anticipate and adapt to seasonal changes in their environments in order to optimally time key developmental events including seasonal growth and flowering of plants, annual bouts of reproduction, dormancy and migration in insects, and the collapse and regrowth of the reproductive system that drives breeding seasons in mammals and birds.Although research on photoperiodic time measurement originally integrated work on plants and animals, recent work has focused more narrowly and separately on plants, invertebrates, or vertebrates. As the fields have become more specialized there has been less interaction across the broader field of photoperiodism. As a result, researchers in each area often needlessly repeat both theoretical and experimental work. For example, understanding that there are genetically distinct morphs among species that, depending on latitude, respond to different critical photoperiods was discovered separately in plants, invertebrates, and vertebrates over the course of 20 years. However, over the past decade, intense work on daily and seasonal rhythms in fruit flies, mustard plants, and hamsters and mice, has led to remarkable progress in understanding the phenomenology, as well as the molecular and genetic mechanisms underlying circadian rhythms and clocks. This book was developed to further this type of cooperation among scientists from all related disciplines. It brings together leading researchers working on photoperiodic timing of seasonal adaptations in plants, invertebrates, and vertebrates. Each of its three sections begins with an introduction by the section editor, and at the end of the book, the section editors present a synthesis of common themes in photoperiodism, as well as discuss similarities and differences in approaches to the study of photoperiodism, and future directions for research on photoperiodic time measurement.

Psychology is of interest to academics from many fields, as well as to the thousands of academic and clinical psychologists and general public who can't help but be interested in learning more about why humans think and behave as they do. This award-winning twelve-volume reference covers every aspect of the ever-fascinating discipline of psychology and represents the most current knowledge in the field. This ten-year revision now covers discoveries based in neuroscience, clinical psychology's new interest in evidence-based practice and mindfulness, and new findings in social, developmental, and forensic psychology.

This book presents evidence that infection is cyclical with the seasons, and that this phenomenon is mirrored in cycles of immune function. The book identifies the mechanisms by which immune systems are bolstered to counteract seasonally-recurrent stressors, such as extreme temperature reductions and food shortages. Stress, infectious diseases, autoimmune diseases, and human cancers are examined, and the role of hormones such as melatonin and glucocorticoids is considered. The book begins with an overview of seasonality, biological rhythms and photoperiodism, and basic immunology, and then discusses seasonal fluctuations in disease prevalence, immune function, and energetics and endocrinology as they relate to immune function. The clinical significance of this issue is also addressed, as such seasonal changes may play an important role in the development and treatment of infections. This first monograph to examine seasonal immune function from an interdisciplinary perspective will serve practitioners as well as advanced undergraduates and graduate students in biology, immunology, human and veterinary medicine, neuroscience, endocrinology, and zoology.

Life on earth has evolved under a consistent cycle of light and darkness caused by the earth's rotation around its axis. This has led to a 24-hour circadian system in most organisms, ranging all the way from fungi to humans. With the advent of electric light in the 19th century, cycles of light and darkness have drastically changed. Shift workers and others exposed to high levels of light at night are at increased risk of health problems, including metabolic syndrome, depression, sleep disorders, dementia, heart disease, and cancer. This book will describe how the circadian system regulates physiology and behavior and consider the important health repercussions of chronic disruption of the circadian system in our increasingly lit world. The research summarized here will interest students in psychology, biology, neuroscience, immunology, medicine, and ecology.

Behavioral neuroendocrinologists are interested in the interactions between hormones and behaviors. This unique book tracks the development of behavioral neuroendocrinology from the first recognized paper in the field by Arnold Berthold in 1849 to the major contributors of the past century. It traces the history and development of the field by exploring the women and men who conducted the studies that revealed these hormone-behavioral relationships. Most chapters are written by the individuals who knew these pioneers best, and describe their stories and discuss the ways in which their work has shaped the field. Now is the perfect time for this book. The field is burgeoning and interest in the development of theoretical perspectives is thriving. Moreover, although this field was dominated by men early on, it has become a field with near sexual parity among its faculty, society membership, and leadership, and thus serves as an example of equitable science, training, and advocacy.

Even sustained exposure to the equivalent of a child's night light has been shown to have an impact on everything from how well our brains function every day to how well our bodies recover from injury. Professor Randy J. Nelson brings together the most reliable research on the different ways exposure to light at night affects how our bodies function and, ultimately, our health. Each chapter explores the role of light and dark in our bodies' most important regulatory processes. In humans, virtually every aspect of our physiology and behavior is mediated by our internal biological clocks. One feature of modern life that may have negative consequences for our health is exposure to light levels that are not aligned with the 24-hour solar day. Circadian rhythms, the internal biological rhythms of our body's processes, require short wavelength (blue) light early during the day to optimize their temporal regulation. Experiencing light at night or insufficient light during the day can lead to a host of problems such as obesity, major depression, bipolar depressive disorder, seasonal affective disorder, sleep disorders, cancer, heart disease and more. Dark Matters sets out to shine a light on the health and well-being consequences of poor circadian hygiene and provide strategies to offset the negative health effects of disrupted circadian rhythms.

Unchecked aggression and violence take a significant toll on society. Even if we manage to avoid being the direct victim of a violent act, the effects of aggression and violence reach us all: We hear about the mauling of a woman by an aggressive dog, our children are bullied at school, or we deal with impulsive violence while commuting to work or attending a sporting event. Reflecting psychology in general, the dominant roles of learning and environmental influences - both social and nonsocial - have traditionally been prominent in discussions of the etiology of human aggression. Biological factors have not been considered sufficiently important to investigate in the search for ways of dealing with human aggression or violence. With recent advances in pharmacology and genetic manipulation techniques, however, new interest has developed in the biological mechanisms of both non-human and human aggression. Although aggression is certainly a complex social behavior with multiple causes, molecular biological factors should not be overlooked, as they may well lead to interventions that prevent excess aggressive behaviors. The primary goal of this book is to summarize and synthesize recent advances in the biological study of aggression. As most aggressive encounters among human and non-human animals represent a male proclivity, the research in this book describes and discusses studies using the most appropriate murine model: testosterone-dependent offensive inter-male aggression, which is typically measured in resident-intruder or isolation-induced aggression tests. The research also emphasizes various molecules that have been linked to aggression tests. The research also emphasizes various molecules that have been linked to aggression by the latest gene-targeting and pharmacological techniques. Although the evidence continues to point to androgens and serotonin (5-HT) as major hormonal and neurotransmitter factors in aggressive behavior, recent work with GABA, dopamine, vasopressin, and other factors, such as nitric oxide, has revealed significant interactions with the neural circuitry underlying aggression. This book is organized according to levels of analysis. The first section examines the genetic contributions to aggression in species ranging from crustaceans to humans. The section summarizes the involvement of various neurotransmitters and neuromodulators in aggressive behavior. The third section summarizes the influence of hormones on aggression, primarily in humans. All chapters emphasize future directions for research on aggression and reveal important domains that have received comparatively less attention in this literature. Considered together, these chapters provide up-to-date coverage of the biology of aggression by some of the leading authorities currently working in this field. Biology of Aggression will direct future research to continue the recent advances in the pharmacological and genetic approaches to understanding aggression and violence. It promises to be a valuable resource for professional and student researchers in neuroscience, psychiatry, cognitive and developmental psychology, behavioral biology, and veterinary medicine.

Life evolves in a cyclic environment, and to be successful, organisms must adapt not only to their spatial habitat, but also to their temporal habitat. How do plants and animals determine the time of year so they can anticipate seasonal changes in their habitats? In most cases, day length, or photoperiod, acts as the principal external cue for determining seasonal activity. For organisms not living at the bottom of the ocean or deep in a cave, day follows night, and the length of the day changes predictably throughout the year. These changes in photoperiod provide the most accurate signal for predicting upcoming seasonal conditions. Measuring day length allows plants and animals to anticipate and adapt to seasonal changes in their environments in order to optimally time key developmental events including seasonal growth and flowering of plants, annual bouts of reproduction, dormancy and migration in insects, and the collapse and regrowth of the reproductive system that drives breeding seasons in mammals and birds.Although research on photoperiodic time measurement originally integrated work on plants and animals, recent work has focused more narrowly and separately on plants, invertebrates, or vertebrates. As the fields have become more specialized there has been less interaction across the broader field of photoperiodism. As a result, researchers in each area often needlessly repeat both theoretical and experimental work. For example, understanding that there are genetically distinct morphs among species that, depending on latitude, respond to different critical photoperiods was discovered separately in plants, invertebrates, and vertebrates over the course of 20 years. However, over the past decade, intense work on daily and seasonal rhythms in fruit flies, mustard plants, and hamsters and mice, has led to remarkable progress in understanding the phenomenology, as well as the molecular and genetic mechanisms underlying circadian rhythms and clocks. This book was developed to further this type of cooperation among scientists from all related disciplines. It brings together leading researchers working on photoperiodic timing of seasonal adaptations in plants, invertebrates, and vertebrates. Each of its three sections begins with an introduction by the section editor, and at the end of the book, the section editors present a synthesis of common themes in photoperiodism, as well as discuss similarities and differences in approaches to the study of photoperiodism, and future directions for research on photoperiodic time measurement.

Psychology is of interest to academics from many fields, as well as to the thousands of academic and clinical psychologists and general public who can't help but be interested in learning more about why humans think and behave as they do. This award-winning twelve-volume reference covers every aspect of the ever-fascinating discipline of psychology and represents the most current knowledge in the field. This ten-year revision now covers discoveries based in neuroscience, clinical psychology's new interest in evidence-based practice and mindfulness, and new findings in social, developmental, and forensic psychology.

This book presents evidence that infection is cyclical with the seasons, and that this phenomenon is mirrored in cycles of immune function. The book identifies the mechanisms by which immune systems are bolstered to counteract seasonally-recurrent stressors, such as extreme temperature reductions and food shortages. Stress, infectious diseases, autoimmune diseases, and human cancers are examined, and the role of hormones such as melatonin and glucocorticoids is considered. The book begins with an overview of seasonality, biological rhythms and photoperiodism, and basic immunology, and then discusses seasonal fluctuations in disease prevalence, immune function, and energetics and endocrinology as they relate to immune function. The clinical significance of this issue is also addressed, as such seasonal changes may play an important role in the development and treatment of infections. This first monograph to examine seasonal immune function from an interdisciplinary perspective will serve practitioners as well as advanced undergraduates and graduate students in biology, immunology, human and veterinary medicine, neuroscience, endocrinology, and zoology.

Life on earth has evolved under a consistent cycle of light and darkness caused by the earth's rotation around its axis. This has led to a 24-hour circadian system in most organisms, ranging all the way from fungi to humans. With the advent of electric light in the 19th century, cycles of light and darkness have drastically changed. Shift workers and others exposed to high levels of light at night are at increased risk of health problems, including metabolic syndrome, depression, sleep disorders, dementia, heart disease, and cancer. This book will describe how the circadian system regulates physiology and behavior and consider the important health repercussions of chronic disruption of the circadian system in our increasingly lit world. The research summarized here will interest students in psychology, biology, neuroscience, immunology, medicine, and ecology.

Behavioral neuroendocrinologists are interested in the interactions between hormones and behaviors. This unique book tracks the development of behavioral neuroendocrinology from the first recognized paper in the field by Arnold Berthold in 1849 to the major contributors of the past century. It traces the history and development of the field by exploring the women and men who conducted the studies that revealed these hormone-behavioral relationships. Most chapters are written by the individuals who knew these pioneers best, and describe their stories and discuss the ways in which their work has shaped the field. Now is the perfect time for this book. The field is burgeoning and interest in the development of theoretical perspectives is thriving. Moreover, although this field was dominated by men early on, it has become a field with near sexual parity among its faculty, society membership, and leadership, and thus serves as an example of equitable science, training, and advocacy.
