Psychobiology Of Gene Expression

The new understanding of the relationships between gene expression and human experience emerging from the Human Genome Project is setting the stage for a profound expansion of our understanding of life. The new neuroscience discoveries about enriching life experiences, neurogenesis, and gene expression are poised to profoundly expand our understanding of psychotherapy and the holistic healing arts. We are just beginning to learn how the brain, the body, and our genes interact in ordinary everyday life to create our lives. Here, acclaimed author and pioneer of new approaches to mindbody communication Ernest Rossi introduces the new science of psychosocial genomics and explores how it will profoundly change our understanding of the pathways of communication among mind, body, and spirit. Integrating modern molecular medicine with traditional holistic healing art and spiritual rites, Rossi documents dramatically new approaches to optimize creativity in psychotherapy and therapeutic hypnosis with both individuals and groups. Part I reviews significant leading-edge neuroscience research on the psychobiology of gene expression and neurogenesis that leads to a new vision of the role of consciousness and creativity in the humanities and the healing arts. Part II explores how to creatively facilitate the psychodynamics of gene expression, neurogenesis, and healing in therapeutic hypnosis, psychotherapy, and human relationships in general. The Psychobiology of Gene Expression illustrates, step-by-step, how to facilitate the natural four-stage creative process on all levels from mind to molecule in our daily work of building a better brain. The book demonstrates how we can use our consciousness and our perception of free will to co-create ourselves in cooperation with nature. Rossi proposes practical approaches to optimize the natural cycles of gene expression in normal consciousness, sleep, dreaming, meditation, and the arts of daily living that are experienced by everyone. A case study spanning two chapters, containing dialog and explanatory commentary, brings the author's work to life and gives readers a deeper appreciation of its clinical application. Rossi's lucid writing style and vivid illustrations inspire this text with a new vision of the creative arts, humanities, and culture in facilitating the optimal development of health, performance, and consciousness.

A proposal for a new model of the evolution of gene regulation networks and development that draws on work from artificial intelligence and philosophy of mind. Each of us is a collection of more than ten trillion cells, busy performing tasks crucial to our continued existence. Gene regulation networks, consisting of a subset of genes called transcription factors, control cellular activity, producing the right gene activities for the many situations that the multiplicity of cells in our bodies face. Genes working together make up a truly ingenious system. In this book, Roger Sansom investigates how gene regulation works and how such a refined but simple system evolved. Sansom describes in detail two frameworks for understanding gene regulation. The first, developed by the theoretical biologist Stuart Kauffman, holds that gene regulation networks are fundamentally systems that repeat patterns of gene expression. Sansom finds Kauffman's framework an inadequate explanation for how cells overcome the difficulty of development. Sansom proposes an alternative: the connectionist framework. Drawing on work from artificial intelligence and philosophy of mind, he argues that the key lies in how multiple transcription factors combine to regulate a single gene, acting in a way that is qualitatively consistent. This allows the expression of genes to be finely tuned to the variable microenvironments of cells. Because of the nature of both development and its evolution, we can gain insight into the developmental process when we identify gene regulation networks as the controllers of development. The ingenuity of genes is explained by how gene regulation networks evolve to control development.

How does the genome, interacting with the multi-faceted environment, translate into the development by which the human brain achieves its astonishing, adaptive array of cognitive and behavioral capacities? Why and how does this process sometimes lead to neurodevelopmental disorders with a major, lifelong personal and social impact? This volume of Progress in Brain Research links findings on the structural development of the human brain, the expression of genes in behavioral and cognitive phenotypes, environmental effects on brain development, and developmental processes in perception, action, attention, cognitive control, social cognition, and language, in an attempt to answer these questions. Leading authors review the state-of-the-art in their field of investigation and provide their views and perspectives for future research Chapters are extensively referenced to provide readers with a comprehensive list of resources on the topics covered All chapters include comprehensive background information and are written in a clear form that is also accessible to the non-specialist

Epigenetics and Behavior: Exploring Biological Determinants of Behavior discusses the evolutionary basis of neurodevelopmental regulation of gene expression by experience (epigenetics). While many areas of scientific inquiry have sought to understand what determines the variation in human attributes (phenotypes) that have consistent trait-like features, including anxiety or fearlessness, aggressive or non-aggressive behavior, social or antisocial behavior, charitable or miserly traits, and so forth, this book takes a comprehensive approach. Over the lifespan of a particular individual, these traits, although flexible, are often highly consistent. The “nature-nurture or “genes versus environment discussion is one of the longstanding arguments in all philosophical inquiry. And now, as we stand on the threshold of a complete understanding of the most fundamental question about human nature, all a result of combined empirical and theoretical advances in epigenetics which influence developmental psychobiology and evolutionary biology, the science is rapidly progressing. With the advent of epigenetics, we now have a mechanism (or mechanisms, really) to explain how this process works at a molecular level – that is, evolutionary selected mechanisms of gene-environment interactions are literally “written into our genetic code. This book draws together the knowledge and ideas from the different fields that collectively have answered the “nature-nurture discussion. Integrates the findings of developmental psychobiology with epigenetics in an evolutionary context Written to convey a new perspective on epigenetic effects on behavior, while maintaining fluid writing prose for the uninformed reader Assembles knowledge from a number of fields, including developmental psychobiology, genomics, epigenetics, and evolutionary biology to paint a precise picture of epigenetic influences on personality

Why do we grow up to look, act, and feel as we do? Through most of the twentieth century, scientists and laypeople answered this question by referring to two factors alone: our experiences and our genes. But recent discoveries about how genes work have revealed a new way to understand the developmental origins of our characteristics. These discoveries have emerged from the new science of behavioral epigenetics--and just as the whole world has now heard of DNA, "epigenetics" will be a household word in the near future. Behavioral epigenetics is important because it explains how our experiences get under our skin and influence the activity of our genes. Because of breakthroughs in this field, we now know that the genes we're born with don't determine if we'll end up easily stressed, likely to fall ill with cancer, or possessed of a powerful intellect. Instead, what matters is what our genes do. And because research in behavioral epigenetics has shown that our experiences influence how our genes function, this work has changed how scientists think about nature, nurture, and human development. Diets, environmental toxins, parenting styles, and other environmental factors all influence genetic activity through epigenetic mechanisms; this discovery has the potential to alter how doctors treat diseases, and to change how mental health professionals treat conditions from schizophrenia to post-traumatic stress disorder. These advances could also force a reworking of the theory of evolution that dominated twentieth-century biology, and even change how we think about human nature itself. In spite of the importance of this research, behavioral epigenetics is still relatively unknown to non-biologists. The Developing Genome is an introduction to this exciting new discipline; it will allow readers without a background in biology to learn about this work and its revolutionary implications.

This entry in the Oxford Library of Psychology compiles cutting- edge research organized around the concept "molecular psychology," which applies principles of molecular biology to the study of behavior and its neural underpinnings. Determining the biological bases for behavior, and the extent to which we can observe and explain their neural underpinnings, requires a bold, broadly defined research methodology. The interdisciplinary entries in this handbook are organized around the principle of "molecular psychology," which unites cutting-edge research from such wide-ranging disciplines as clinical neuroscience and genetics, psychology, behavioral neuroscience, and neuroethology. For the first time in a single volume, leaders in diverse research areas use molecular approaches to investigate social behavior, psychopathology, emotion, cognition and stress in healthy volunteers, patient populations, and an array of non-human species including rodents, insects, fish, and non-human primates. Chapters draw on molecular methods covering candidate genes, genome-wide association studies, copy number variations, gene expression studies, and epigenetics while addressing the ethical, legal, and social issues to emerge from this new and exciting research approach.

ELLIOTT M. BLASS Fifteen years have passed since the first volume on developmental psychobiology (Blass, 1986) appeared in this series and 13 since the publication of the second volume (Blass, 1988). These volumes documented the status of the broad domain of scientific inquiry called developmental psychobiology and were also written with an eye to the future. The future has been revolutionary in at least three ways. First, there was the demise of a descriptive ethology as we had known it, to be replaced first by sociobiology and later by its more sophisticated versions based on quantitative predictions of social interactions that reflected relatedness and inclu sive fitness. Second, there was the emergence of cognitive science, including cogni tive development, as an enormously strong and interactive multidisciplinary effort. Making the "functional" brain more accessible made this revolution all the more relevant to our discipline. In the laboratory, immunocytochemical detection of immediate / early genes, such as los, now allows us to trace neuronal circuits activated during complex behaviors. The "functional" brain of primates, especially humans, was also made very accessible through neuroimaging with which we can look at and into brains as they solve and attempt to solve particular tasks. Those of us who were trained in neurology as graduate students two or three decades ago recognize only the people in white coats and patients in beds or on gurneys when we visit neurologi cal units today. The rest is essentially new.
