This is the last major work of Eugene N. Sokolov, Professor of Psychophysiology at Moscow State University from 1950 to 2008. It summarizes the contributions of a lifetime on the neural mechanism of consciousness. Working at the intersection of psychology, neurophysiology and mathematics, Sokolov early introduced the concept of quantifiable 'difference in neuronal activity' and 'cognitive distance' as corresponding metrics in the physical and mental models of reality. He demonstrated the power of multidimensional vector mathematics to represent the neural computations that mediate between the brain's neural model and the mind's mental model of reality. Sokolov and colleagues showed a mathematical commonality among the neuronal mechanisms that mediate the perception of basic features of visual stimuli including color, brightness, line orientation and motion. This led to a general vector model linking perceptual and memory processes to adaptive motor mechanisms. They extended the model to encompass broader, more complex functions, such as the perception of emotions in facial expressions, semantic differences in verbal stimuli and differential executive control mechanisms. Integrating evidence from human psychophysics, animal neurophysiology and vector mathematics they developed a unified model to characterize quantitatively many complex relations between objective and subjective aspects of reality. Sokolov's studies of neuronal mechanisms of mental phenomena led him to distinguish two categories of neurons: 'consciousness neurons' directly associated with awareness of perceptual, emotional and cognitive events, and neurons that are necessary for, but not directly involved in, conscious processes. The book integrates his findings with major themes shaping twenty-first century understanding of the brain-mind relationship. It relates the findings both to work of other Russian investigators, such as Pavlov, Luria, and Rusinov, and to work of many Western researchers, including von Bekesy, Eccles, Edelman, Ehrenstein, Grossberg, John, Koch and Crick, Ledoux, Llinas, Milner, Penfield, Penrose, Posner, and Schrödinger.

The science and practice of feeling our movements, sensations, and emotions. When we are first born, before we can speak or use language to express ourselves, we use our physical sensations, our “body sense,” to guide us toward what makes us feel safe and fulfilled and away from what makes us feel bad. As we develop into adults, it becomes easy to lose touch with these crucial mind-body communication channels, but they are essential to our ability to navigate social interactions and deal with psychological stress, physical injury, and trauma. Combining a ground-up explanation of the anatomical and neurological sources of embodied self-awareness with practical exercises in touch and movement, Body Sense provides therapists and their clients with the tools to attain mind-body equilibrium and cultivate healthy body sense throughout their lives.

In our high-speed culture, terms like "stressed-out," "Type-A personality," "biofeedback," and "relaxation response" have become commonplaces. More than ever before, we are aware of the relationship between our mental and emotional states and our physical well-being. Findings from the field of psychophysiology, which investigates the reflexive interaction between psychology and physiology, have revised our approach to illness and its prevention and treatment. We know, for example, that stress, combined with other factors, increases vulnerability to heart attack and stroke. Successful treatment must include lifestyle changes to reduce the effects of stress on the body. In this important text, Kenneth Hugdahl presents a comprehensive introduction to the history, methods, and applications of psychophysiology and explores other areas concerned with the "mind-body interface," such as psychosomatic medicine, behavioral medicine, clinical psychology, psychiatry, neuropsychology, and cognitive neuroscience. By showing how social, behavioral, cognitive, and emotional events are mirrored in physiological processes, he gives us a clearer understanding of complex cognitive processes. This book illustrates psychophysiology's importance as a research and clinical tool and highlights its many contributions to the assessment and diagnosis of physical disorders. It also provides a framework for extending psychophysiological insights to other areas of psychology and neuroscience.

Philosophical 'thought experiments' invoking inverted spectra, zombies, et cetera suggest that conscious sensations have no function, and psychological studies finding no correlation between vivid visual imaging and visual problem solving suggest that conscious images have no function. Furthermore, both philosophical and psychological theories suggest that self-consciousness has no function. Countering such suggestions, the post-Darwinian double-aspect theory which Professor Robert Kunzendorf's introduces in the first chapter of his monograph On the Evolution of Conscious Sensation, Conscious Imagination, and Consciousness of Self points to evolutionary functions of certain sensations, youngling vivid images, and self-consciousness. Kunzendorf's second chapter presents evidence that the most primitive sensation-pain, the subjective aspect of free nerve endings or nociceptors-has a survival-promoting function. But as the pressure nociceptor mutates into a touch receptor, the heat nociceptor into temperature receptor, and the chemical nociceptor into a taste receptor, the painful qualia of these nociceptors evolve respectively into touch sensation, temperature sensation, or taste sensation-painless sensations that add no survival benefit to their receptor's physical aspect. Building on evidence that retinal receptors embodying visual qualia evolved from primitive eyespots responsive to injurious 'heat at a distance' or painful light, the third chapter presents evidence that visually imagined sensations are the subjective qualities of retinal receptors that are corticofugally innervated in warm-blooded animals-for the developmental purpose of testing cortically hypothesized sensory-motor rules that have greater survival value than cold-blooded stimulus-response associations. The fourth and final chapter focuses on self-conscious reality-testing and on visuo-spatial self-conceptualization, and presents evidence that such manifestations of self-awareness evolve only in those warm-blooded animals whose rule-developing youth lasts two years or longer-that is, those mammals and birds whose survival during the imaginal testing of rules is subjected to prolonged risk if self-consciousness that one is imaging sensations (rather than perceiving sensations) is absent.

Research in music is a multidisciplinary matter. Experts from very different fields in science report the most recent data from their own research and thereby show today's knowledge concerning music and neuropsychological sciences. This includes the developing and adult brain, neurological and psychiatric diseases as well as the battery of the most recent development in brain imaging techniques. This book offers an excellent introduction to new scientific efforts in understanding both neuronal and psychic mechanisms when listening to or performing music.

In this wide-ranging book, one of the boldest thinkers in modern neuroscience confronts an ancient philosophical problem: can we know the world as it really is? Drawing on provocative new findings about the psychophysiology of perception and judgment in both human and nonhuman primates, and also on the cultural history of science, Jean-Pierre Changeux makes a powerful case for the reality of scientific progress and argues that it forms the basis for a coherent and universal theory of human rights. On this view, belief in objective knowledge is not a mere ideological slogan or a naive confusion; it is a characteristic feature of human cognition throughout evolution, and the scientific method its most sophisticated embodiment. Seeking to reconcile science and humanism, Changeux holds that the capacity to recognize truths that are independent of subjective personal experience constitutes the foundation of a human civil society.
