Arousal is fundamental to all cognition. It is intuitively obvious, absolutely necessary, but what exactly is it? In Brain Arousal and Information Theory, Donald Pfaff presents a daring perspective on this long-standing puzzle. Pfaff argues that, beneath our mental functions and emotional dispositions, a primitive neuronal system governs arousal. Employing the simple but powerful framework of information theory, Pfaff revolutionizes our understanding of arousal systems in the brain. Starting with a review of the neuroanatomical, neurophysiological, and neurochemical components of arousal, Pfaff asks us to look at the gene networks and neural pathways underlying the brain's arousal systems much as a design engineer would contemplate information systems. This allows Pfaff to postulate that there is a bilaterally symmetric, bipolar system universal among mammals that readies the animal or the human being to respond to stimuli, initiate voluntary locomotion, and react to emotional challenges. Applying his hypothesis to heightened states of arousal--sex and fear--Pfaff shows us how his theory opens new scientific approaches to understanding the structure of brain arousal. A major synthesis of disparate data by a preeminent neuroscientist, Brain Arousal and Information Theory challenges current thinking about cognition and behavior. Whether you subscribe to Pfaff's theory or not, this book will stimulate debate about the nature of arousal itself.

Can the psychodynamics of the mind be correlated with neurodynamic processes in the brain? The book revisits a question that scientists and psychoanalysts have been asking for more than a century. It brings together experts from Psychology, Psychoanalysis, Neuroscience, Philosophy, Psychiatry and Neurology to consider this question.

A succinct, neurobiological explanation of the pathways that 'wake up the brain' from deep anesthesia, sleep and brain injury.

What are the physical paths towards consciousness? How do humans transition out of deep anesthesia, deep sleep, or traumatic brain injury? This book presents a new argument that expands past theories centered on the cerebral cortex, and instead emphasizes the longitudinally-integrated brainstem systems that are essential to the mechanism of consciousness. The workings of these vertical pathways that 'wake up the brain' are examined in neurobiological and molecular detail. Mirroring the evolution of this system from fish to humans, chapters in the book move from hindbrain to forebrain and from animal brain to human brain, developing the unified approach involved in the brain arousal mechanism. Considering consciousness through an array of neuronal structures, this book provides a new physical explanation of the phenomenon. Written for neurologists, neuroscientists, psychologists and psychiatrists, the book's succinct and readable tone means it is also suitable for readers interested in the workings of the brain.

An investigation of the aesthetics and politics of new visual media under twenty-first-century capitalism, from console games to virtual reality to video installation art. In Biopolitical Screens, Pasi Väliaho charts and conceptualizes the imagery that composes our affective and conceptual reality under twenty-first-century capitalism. Väliaho investigates the role screen media play in the networks that today harness human minds and bodies—the ways that images animated on console game platforms, virtual reality technologies, and computer screens capture human potential by plugging it into arrangements of finance, war, and the consumption of entertainment. Drawing on current neuroscience and political and economic thought, Väliaho argues that these images work to shape the atomistic individuals who populate the neoliberal world of accumulation and war. Väliaho bases his argument on a broad notion of the image as something both visible and sayable, detectable in various screen platforms but also in scientific perception and theoretical ideas. After laying out the conceptual foundations of the book, Väliaho offers focused and detailed investigations of the current visual economy. He considers the imagery of first-person shooter video games as tools of “neuropower”; explores the design and construction of virtual reality technologies to treat post-traumatic stress disorder in veterans of Iraq and Afghanistan; and examines three instances of video installation art that have the power to disrupt the dominant regime of sensibility rather than reinforce it.

This book constitutes the proceedings of the First Indo-Japanese conference on Perception and Machine Intelligence, PerMIn 2012, held in Kolkata, India, in January 2012. The 41 papers, presented together with 1 keynote paper and 3 plenary papers, were carefully reviewed and selected for inclusion in the book. The papers are organized in topical sections named perception; human-computer interaction; e-nose and e-tongue; machine intelligence and application; image and video processing; and speech and signal processing.

Edited and authored by a wealth of international experts in neuroscience and related disciplines, this key new resource aims to offer medical students and graduate researchers around the world a comprehensive introduction and overview of modern neuroscience. Neuroscience research is certain to prove a vital element in combating mental illness in its various incarnations, a strategic battleground in the future of medicine, as the prevalence of mental disorders is becoming better understood each year. Hundreds of millions of people worldwide are affected by mental, behavioral, neurological and substance use disorders. The World Health Organization estimated in 2002 that 154 million people globally suffer from depression and 25 million people from schizophrenia; 91 million people are affected by alcohol use disorders and 15 million by drug use disorders. A more recent WHO report shows that 50 million people suffer from epilepsy and 24 million from Alzheimer’s and other dementias. Because neuroscience takes the etiology of disease—the complex interplay between biological, psychological, and sociocultural factors—as its object of inquiry, it is increasingly valuable in understanding an array of medical conditions. A recent report by the United States’ Surgeon General cites several such diseases: schizophrenia, bipolar disorder, early-onset depression, autism, attention deficit/ hyperactivity disorder, anorexia nervosa, and panic disorder, among many others. Not only is this volume a boon to those wishing to understand the future of neuroscience, it also aims to encourage the initiation of neuroscience programs in developing countries, featuring as it does an appendix full of advice on how to develop such programs. With broad coverage of both basic science and clinical issues, comprising around 150 chapters from a diversity of international authors and including complementary video components, Neuroscience in the 21st Century in its third edition serves as a comprehensive resource to students and researchers alike.
