Neurobiology Of Human Values

Man has been pondering for centuries over the basis of his own ethical and aesthetic values. Until recent times, such issues were primarily fed by the thinking of philosophers, moralists and theologists, or by the findings of historians or sociologists relating to universality or variations in these values within various populations. Science has avoided this field of investigation within the confines of philosophy. Beyond the temptation to stay away from the field of knowledge science may also have felt itself unconcerned by the study of human values for a simple heuristic reason, namely the lack of tools allowing objective study. For the same reason, researchers tended to avoid the study of feelings or consciousness until, over the past two decades, this became a focus of interest for many neuroscientists. It is apparent that many questions linked to research in the field of neuroscience are now arising. The hope is that this book will help to formulate them more clearly rather than skirting them. The authors do not wish to launch a new moral philosophy, but simply to gather objective knowledge for reflection.

For ages there has been a gap between the two cultures of the sciences and religions. According to Roger Sperry, science can now bridge the gap between the cold hard facts of the sciences and humanitarian and religious values. Sperry won the Nobel Prize in 1981 for his work on the differences between the left and right halves of the brain. For the past twenty years he has been campaigning for human consciousness and values to be investigated scientificlly. This book describes Sperry's work and his struggle to guide humanity beyond a world divided. terms such as consciousness, value, love and joy are scientifically meaningful, just like terms referring to brain physiology, such as neural pathways and electrical impulse. The split between mind matter, or religion, and science can be removed, says Sperry, by expanding scientific research. Now, conscious experiences must be taken into account as scientific information about the brain. Our values, beliefs and goals can directly affect our brain states and physiology.

Looks at developments in genetics, cell growth, neurobiology, and evolution, and ethical issues raised by biological research

Winner of the William James Book Award Winner of the inaugural Expanded Reason Award A wide-ranging exploration of the role of childhood experiences in adult morality. Moral development has traditionally been considered a matter of reasoning—of learning and acting in accordance with abstract rules. On this model, largely taken for granted in modern societies, acts of selfishness, aggression, and ecological mindlessness are failures of will, moral problems that can be solved by acting in accordance with a higher rationality. But both ancient philosophy and recent scientific scholarship emphasize implicit systems, such as action schemas and perceptual filters that guide behavior and shape human development. In this integrative book, Darcia Narvaez argues that morality goes “all the way down” into our neurobiological and emotional development, and that a person’s moral architecture is largely established early on in life. Moral rationality and virtue emerge “bottom up” from lived experience, so it matters what that experience is. Bringing together deep anthropological history, ethical philosophy, and contemporary neurobiological science, she demonstrates where modern industrialized societies have fallen away from the cultural practices that made us human in the first place. Neurobiology and the Development of Human Morality advances the field of developmental moral psychology in three key ways. First, it provides an evolutionary framework for early childhood experience grounded in developmental systems theory, encompassing not only genes but a wide array of environmental and epigenetic factors. Second, it proposes a neurobiological basis for the development of moral sensibilities and cognition, describing ethical functioning at multiple levels of complexity and context before turning to a theory of the emergence of wisdom. Finally, it embraces the sociocultural orientations of our ancestors and cousins in small-band hunter-gatherer societies—the norm for 99% of human history—for a re-envisioning of moral life, from the way we value and organize child raising to how we might frame a response to human-made global ecological collapse. Integrating the latest scholarship in clinical sciences and positive psychology, Narvaez proposes a developmentally informed ecological and ethical sensibility as a way to self-author and revise the ways we think about parenting and sociality. The techniques she describes point towards an alternative vision of moral development and flourishing, one that synthesizes traditional models of executive, top-down wisdom with “primal” wisdom built by multiple systems of biological and cultural influence from the ground up.

What is morality? Where does it come from? And why do most of us heed its call most of the time? In Braintrust, neurophilosophy pioneer Patricia Churchland argues that morality originates in the biology of the brain. She describes the "neurobiological platform of bonding" that, modified by evolutionary pressures and cultural values, has led to human styles of moral behavior. The result is a provocative genealogy of morals that asks us to reevaluate the priority given to religion, absolute rules, and pure reason in accounting for the basis of morality. Moral values, Churchland argues, are rooted in a behavior common to all mammals--the caring for offspring. The evolved structure, processes, and chemistry of the brain incline humans to strive not only for self-preservation but for the well-being of allied selves--first offspring, then mates, kin, and so on, in wider and wider "caring" circles. Separation and exclusion cause pain, and the company of loved ones causes pleasure; responding to feelings of social pain and pleasure, brains adjust their circuitry to local customs. In this way, caring is apportioned, conscience molded, and moral intuitions instilled. A key part of the story is oxytocin, an ancient body-and-brain molecule that, by decreasing the stress response, allows humans to develop the trust in one another necessary for the development of close-knit ties, social institutions, and morality. A major new account of what really makes us moral, Braintrust challenges us to reconsider the origins of some of our most cherished values.

Decision Neuroscience addresses fundamental questions about how the brain makes perceptual, value-based, and more complex decisions in non-social and social contexts. This book presents compelling neuroimaging, electrophysiological, lesional, and neurocomputational models in combination with hormonal and genetic approaches, which have led to a clearer understanding of the neural mechanisms behind how the brain makes decisions. The five parts of the book address distinct but inter-related topics and are designed to serve both as classroom introductions to major subareas in decision neuroscience and as advanced syntheses of all that has been accomplished in the last decade. Part I is devoted to anatomical, neurophysiological, pharmacological, and optogenetics animal studies on reinforcement-guided decision making, such as the representation of instructions, expectations, and outcomes; the updating of action values; and the evaluation process guiding choices between prospective rewards. Part II covers the topic of the neural representations of motivation, perceptual decision making, and value-based decision making in humans, combining neurcomputational models and brain imaging studies. Part III focuses on the rapidly developing field of social decision neuroscience, integrating recent mechanistic understanding of social decisions in both non-human primates and humans. Part IV covers clinical aspects involving disorders of decision making that link together basic research areas including systems, cognitive, and clinical neuroscience; this part examines dysfunctions of decision making in neurological and psychiatric disorders, such as Parkinson’s disease, schizophrenia, behavioral addictions, and focal brain lesions. Part V focuses on the roles of various hormones (cortisol, oxytocin, ghrelin/leptine) and genes that underlie inter-individual differences observed with stress, food choices, and social decision-making processes. The volume is essential reading for anyone interested in decision making neuroscience. With contributions that are forward-looking assessments of the current and future issues faced by researchers, Decision Neuroscience is essential reading for anyone interested in decision-making neuroscience. Provides comprehensive coverage of approaches to studying individual and social decision neuroscience, including primate neurophysiology, brain imaging in healthy humans and in various disorders, and genetic and hormonal influences on decision making Covers multiple levels of analysis, from molecular mechanisms to neural-systems dynamics and computational models of how we make choices Discusses clinical implications of process dysfunctions, including schizophrenia, Parkinson’s disease, eating disorders, drug addiction, and pathological gambling Features chapters from top international researchers in the field and full-color presentation throughout with numerous illustrations to highlight key concepts

WALTER A. ROSENBLITH Footnotes to the Recent History of Neuroscience: Personal Reflections and Microstories The workshop upon which this volume is based offered me an opportunity to renew contact fairly painlessly with workers in the brain sciences, not just as a participant/observer but maybe as what might be called a teller of microstories. I had originally become curious about the brain by way of my wife's senior thesis, in which she attempted to relate electroencephalography to certain aspects of human behavior. As a then-budding physicist and communications engineer, I had barely heard about brain waves, nor had I studied physiology in a systematic way. My work on noise dealt with the effects of certain acoustical stimuli on biological structures and entire organisms. This was the period immediately after World War II when many scientists and engineers who had done applied work in the war effort were trying to find their way among the challenging new fields that were opening up. Francis Crick, among others, has described such a search taking place in the cafes of the "other" Cambridge, the one on the Cam. At that time the brain sciences, in his opinion, offered much less promise than molecular biology. However, he was sufficiently attracted by what they might eventually have to offer to keep an eye on them, and several decades later his work turned toward the brain.

Existentialisms arise when the foundations of being, such as meaning, morals, and purpose come under assault. In the first-wave of existentialism, writings typified by Kierkegaard, Dostoevsky, and Nietzsche concerned the increasingly apparent inability of religion, and religious tradition, to support a foundation of being. Second-wave existentialism, personified philosophically by Sartre, Camus, and de Beauvoir, developed in response to similar realizations about the overly optimistic Enlightenment vision of reason and the common good. The third-wave of existentialism, a new existentialism, developed in response to advances in the neurosciences that threaten the last vestiges of an immaterial soul or self. Given the increasing explanatory and therapeutic power of neuroscience, the mind no longer stands apart from the world to serve as a foundation of meaning. This produces foundational anxiety. In Neuroexistentialism, a group of contributors that includes some of the world's leading philosophers, neuroscientists, cognitive scientists, and legal scholars, explores the anxiety caused by third-wave existentialism and possible responses to it. Together, these essays tackle our neuroexistentialist predicament, and explore what the mind sciences can tell us about morality, love, emotion, autonomy, consciousness, selfhood, free will, moral responsibility, law, the nature of criminal punishment, meaning in life, and purpose.

This book is unique in expanding the boundaries of neuroscience, while remaining solidly grounded within it. In this, it outlines a new plateau of wider integrative understanding both within and beyond neuroscience. The book advances the view and implications of an integrated functional unity of consciousness and brain, inclusive of freedom of will. It reaches from first principles of human awareness and apprehension and the physical foundations of consciousness, through a structured integrative view of consciousness and the brain, to outlines of the ambient contextual influences of human living. Comprehensive overviews of brain theory and theoretical neuroscience are given. Fundamental brain functions of human apprehension, language, value, aesthetics, rational and extrarational knowing, biological primals, and adaptive integrations are seen to operate within such ambient influences as whole of nature, human plight, circumstances, personal life, good and evil, inner depths, worlds of man, and enlightenments.Prof Ronald MacGregor has published extensively in theoretical neuroscience since 1965, consistently advocating the foundationality of physiology and physical law in brain-mind function. His work has helped ground neuroelectric signaling within physical science and characterize the neuroelectric patterns of neurons and neural networks.
