Can there be a science of consciousness? This issue has been the focus of three landmark conferences sponsored by the University of Arizona in Tucson. The first two conferences and books have become touchstones for the field. This volume presents a selection of invited papers from the third conference. Can there be a science of consciousness? This issue has been the focus of three landmark conferences sponsored by the University of Arizona in Tucson. The first two conferences and books have become touchstones for the field. This volume presents a selection of invited papers from the third conference. It showcases recent progress in this maturing field by researchers from philosophy, neuroscience, cognitive psychology, phenomenology, and physics. It is divided into nine sections: the explanatory gap, color, neural correlates of consciousness, vision, emotion, the evolution and function of consciousness, physical reality, the timing of conscious experience, and phenomenology. Each section is preceded by an overview and commentary by the editors. Contributors Dick J. Bierman, Jeffrey Burgdorf, A. Graham Cairns-Smith, William H. Calvin, Christian de Quincey, Frank H.

Current thinking and research on consciousness and the brain.

Human consciousness has perplexed philosophers, artists and scientists for centuries. Some hold it to be purely physical, while others believe it transcends the material world. Now comes a book that offers a new perspective - based entirely on evidence from the natural sciences - whereby materialism and dualism co-exist. The author - a distinguished pioneer of nonlinear dynamics - bases his argument on a hierarchical view of mental organization; a stairway. Atoms give rise to molecules, neurons form the brain and individual consciousness leads to shared culture. All steps are needed to complete the picture and each level derives from the previous one. The book shows specialists how each of their fields adds to the overall picture, while providing general readers with an introduction to this investigation.

Philosophers of mind have been arguing for decades about the nature of phenomenal consciousness and the relation between brain and mind. More recently, neuroscientists and philosophers of science have entered the discussion. Which neural activities in the brain constitute phenomenal consciousness, and how could science distinguish the neural correlates of consciousness from its neural constitution? At what level of neural activity is consciousness constituted in the brain and what might be learned from well-studied phenomena like binocular rivalry, attention, memory, affect, pain, dreams and coma? What should the science of consciousness want to know and what should explanation look like in this field? How should the constitution relation be applied to brain and mind and are other relations like identity, supervenience, realization, emergence and causation preferable? Building on a companion volume on the constitution of visual consciousness (AiCR 90), this volume addresses these questions and related empirical and conceptual territory. It brings together, for the first time, scientists and philosophers to discuss this engaging interdisciplinary topic.

How do our personalities and mental processes, our " states of consciousness" , derive from a gray mass of tissue with the consistency of a soft-boiled egg? How can mere molecules constitute an idea or emotion? Some of the most important questions we can ask are about our own consciousness. Our personalities, our individuality, indeed our whole reason for living, lie in the brain and in the elusive phenomenon of consciousness it generates. Thinkers in many disciplines have long struggled with such questions, often in ways that have seemed incompatible, if not downright contradictory. Philosophers have meditated on the subjective experience of consciousness, with little attention to the physical realm, while scientists have sought to establish a causal relation between brain function and mind, often ignoring the qualitative aspects of experience. In Journey to the Centers of the Mind, neuroscientist Susan Greenfield offers an intriguing, unifying theory of consciousness that encompasses both phenomenological mental events and physical aspects of brain function. Using information gathered from clues in animal behavior, human brain damage, computer science, neurobiology, and philosophy, Greenfield offers a " concentric theory" of consciousness, and shows how certain events in the brain correspond to our qualitative experience of the world. Demonstrating the ways in which we can interpret the experience of consciousness in terms of interactions among neurons, she explores how much we can learn by continuing to find the links between our physical and mental inner worlds.

The Reaching for Mind workshop, held at AISB 95, explicitly addressed itself to the current crisis in Cognitive Science. In particular, the issue of how this discipline can address consciousness was a leitmotiv in the workshop. The conclusion seems inescapable that there is a need for two sciences in this area. Cognitive Science can be freed to become a fully-fledged experimental epistemology by the creation of a science of consciousness also encompassing subjectivity. This exciting collection of papers indicates where both these sciences may be heading. (Series B)The programme committee of the workshop included: Mike Brady (Oxford); Daniel Dennett (Tufts); Jerry Feldman (Berkeley); John Macnamara (McGill) and Zenon Pylyshyn (Rutgers).

Scholars from many different disciplines examine consciousness through the lens of intellectual approaches and cultures ranging from cosmology research and cell biophysics laboratories to pre-Columbian Mesoamerica and Tibetan Tantric Buddhism in a volume that extends consciousness studies beyond the limits of current neuroscience research. The "hard problem" of today's consciousness studies is subjective experience: understanding why some brain processing is accompanied by an experienced inner life. Recent scientific advances offer insights for understanding the physiological and chemical phenomenology of consciousness. But by leaving aside the internal experiential nature of consciousness in favor of mapping neural activity, such science leaves many questions unanswered. In Ontology of Consciousness, scholars from a range of disciplines—from neurophysiology to parapsychology, from mathematics to anthropology and indigenous non-Western modes of thought—go beyond these limits of current neuroscience research to explore insights offered by other intellectual approaches to consciousness. These scholars focus their attention on such philosophical approaches to consciousness as Tibetan Tantric Buddhism, North American Indian insights, pre-Columbian Mesoamerican civilization, and the Byzantine Empire. Some draw on artifacts and ethnographic data to make their point. Others translate cultural concepts of consciousness into modern scientific language using models and mathematical mappings. Many consider individual experiences of sentience and existence, as seen in African communalism, Hindi psychology, Zen Buddhism, Indian vibhuti phenomena, existentialism, philosophical realism, and modern psychiatry. Some reveal current views and conundrums in neurobiology to comprehend sentient intellection.
