Biomedical research in the first decade of the 21st century has been marked by a rapidly growing interest in epigenetics. The reasons for this are numerous, but primarily it stems from the mounting realization that research programs focused solely on DNA sequence variation, despite their breadth and depth, are unlikely to address all fundamental aspects of human biology. Some questions are evident even to non-biologists. How does a single zygote develop into a complex multicellular organism composed of dozens of different tissues and hundreds of cell types, all genetically identical but performing very different functions? Why do monozygotic twins, despite their stunning external similarities, often exhibit significant differences in personality and predisposition to disease? If environmental factors are solely the cause of such variation, why are similar differences also observed between genetically identical animals housed in a uniform environment? Over the last couple of decades, epigenetics has undergone a significant metamorphosis from an abstract developmental theory to a very dynamic and rapidly developing branch of molecular biology. This volume represents a compilation of our current understanding about the key aspects of epigenetic processes in the brain and their role in behavior. The chapters in this book bring together some of the leading researchers in the field of behavioral epigenetics. They explore many of the epigenetic processes which operate or may be operating to mediate neurobiological functions in the brain and describe how perturbations to these systems may play a key role in mediating behavior and the origin of brain diseases.

What lies at the heart of neuronal plasticity? Accumulating evidence points to epigenetics. This word originally indicated potentially heritable modifications in gene expression that do not involve changes in DNA sequence. Today this definition is much less strict, and epigenetic control is thought to include DNA methylation, histone modifications, histone variants, microRNA metabolic pathways and non-histone proteins modifications. Thus, while neuronal plasticity is rightly thought to be intimately associated to genomic control, it is critical to appreciate that there is much more to the genome than DNA sequence. Recent years have seen spectacular advances in the field of epigenetics. These have attracted the interest of researchers in many fields and evidence connecting epigenetic regulation to brain functions has been accumulating. Neurons daily convert a variety of external stimuli into rapid or long-lasting changes in gene expression. A variety of studies have centered on the molecular mechanisms implicated in epigenetic control and how these may operate in concert. It will be critical to unravel how specificity is achieved. Importantly, specific modifications seem to mediate both developmental processes and adult brain functions, such as synaptic plasticity and memory. Many aspects of the research in neurosciences and endocrinology during the upcoming decade will be dominated by the deciphering of epigenetic control. This book constitutes a compendium of the most updated views in the field.

The field of neuroendocrinology has extended from the initial interest in the hypothalamic control of pituitary secretion to embrace multiple reciprocal interactions between the central nervous system (CNS) and endocrine systems in the coordination of homeostasis and various physiological responses from adaptation to disease. Most recently, epigenetic mechanisms were recognized for their role in the development of the neuroendocrine axes as well as in the mediation of gene-environment interactions in stress-related psychiatry disorders.

Discover why animals do what they do, based on their genes, physiologies, cultures, traditions, survival and mating advantages, and evolutionary histories—and find out how studying behavior in the animal world helps us understand human behavior. The three volumes of Animal Behavior: How and Why Animals Do the Things They Do cover the breadth of the field, addressing causation, development, function, and evolution in a wide range of animals, from invertebrates to humans. Inspired by Nobel laureate Nikolaas Tinbergen's work, the first two volumes follow Tinbergen's four classic questions of animal behavior, while the third volume supplies integrated examples of Tinbergen's investigative process applied in specific cases. Written in an engaging, accessible manner ideal for college students as well as general audiences, this evidence-based collection provides a fascinating tour of animal behaviorists' findings, such as how animal communication can be truthful or deceitful, the deadly serious business behind clashes in the "battle of the sexes," and how documentation of animal behavior can lead to a deeper understanding of human behavior. Each chapter provides both historical background and information about current developments in animal behavior knowledge.

This stimulating volume addresses vital questions about gene/environment interactions as they affect cell health from the prenatal period through later life. Beginning with a tour of epigenetic processes in the human body, the book assembles current theoretical and empirical developments across the discipline, among them transgenerational epigenetic inheritance, the effects of maternal nutrition on epigenetic change, and possible links between epigenetics and childhood obesity. Public health and policy aspects of the field are discussed in depth, with the understanding that much can be done to improve our epigenetic health as a species. And in this vein, contributors consider future possibilities, such as the reprogramming of genes to reverse cancer and other diseases. Included in the coverage: The role of environmental epigenetics in perinatal and neonatal development The epigenetic biomarker γH2AX: from bench science to clinical trials What’s the risk? Dental amalgam, mercury exposure, and human health risks throughout the lifespan Post-traumatic stress disorder: neurological, genetic, and epigenetic bases Children’s exposure to alcohol, tobacco, and drugs: long-term outcomes Ethical implications of epigenetics Epigenetics, the Environment, and Children’s Health Across Lifespans brings real-world knowledge and applications of this increasingly important field to public health practitioners, maternal and child health researchers, and environmental health experts.

Cabej (biology, U. of Tirana, Albania) explains the epigenetic principles of evolution (as opposed to the theory of evolution as determined by changes in genes) and reconstructs the developmental mechanisms of evolutionary changes in metazoans, based on empirical evidence. He focuses on the mechanisms of the generation of the evolutionary innovations from the influence of environment on heredity rather than the role of natural selection. He discusses control systems and determination of phenotypic traits in metazoans, neural manipulation of gene expression, epigenetic control of reproduction and early development, neural control of postphylotypic development, and the epigenetic system of inheritance. He follows with description of neural-developmental premises of evolutionary adaptation, including evolution and stress responses and behavioral adaptation to changes in environment, ontogeny, and intragenerational developmental plasticity; epigenetics of circumevolutionary phenomena and the mechanism of evolutionary change, including transgenerational developmental plasticity and the evolution of metazoans and their control system; and the origins of evolutionary novelty, evolution by loss or by reverting to ancestral characters, neural crest-determined evolutionary novelties, evolutionary convergences, species and allopatric speciation, and sympatric speciation. He presents the available evidence for his theory, rather than illustrating an established theory, and includes a comparative presentation of the neo-Darwinian view to his epigenetic explanation.

Stress and Epigenetics in Suicidediscusses the central role of epigenetic modifications in suicidal behavior. As early-life stress and an individual's ability to cope with such stressors, combined with psychological factors, social factors, and existential and cognitive factors can predispose young people to suicidal behavior and put them at added risk of suicidal behavior later in life, this book provides readers with an overview of the neurobiology of stress, an introduction to the epigenetic changes induced by stress, and an understanding of how vulnerability and resilience to stress are built. It integrates these mechanisms into a biobehavioral model of suicide based on epigenetic marks, gene-environment interactions, and other stressors. More importantly, it provides future direction for research and discusses potential interventions. This book is an ideal and trusted resource for researchers and clinicians who are interested in learning how the environment can affect behavior through genetics, and for those seeking the development of new methods for suicide prevention. - Explores the neurobiology of stress and stress-related epigenetics, including discussion of the role of stress-induced epigenetic changes in behavioral, emotional, and cognitive mechanisms and whether these epigenetic marks are transgenerational - Provides compelling biobehavioral models of suicide based on genetics, epigenetics, and behavioral adjustment - Integrates social, psychological, and existential influences, giving readers a better understanding of the interdisciplinary nature of suicide risk factors - Presents future directions for suicide-prevention strategies that incorporate recent research on genomics and stress resilience

Genes, Brain Function, and Behavior offers a concise description of the nervous system that processes sensory input and initiates motor movements. It reviews how behaviors are defined and measured, and how experts decide when a behavior is perturbed and in need of treatment. Behavioral disorders that are clearly related to a defect in a specific gene are reviewed, and the challenges of understanding complex traits such as intelligence, autism and schizophrenia that involve numerous genes and environmental factors are explored. New methods of altering genes offer hope for treating or even preventing difficulties that arise in our genes. This book explains what genes are, what they do in the nervous system, and how this impacts both brain function and behavior.
