After being sorely neglected for some time, consciousness is well and truly back on the philosophical and scientific agenda. This entry provides a whistle-stop tour of some recent debates surrounding consciousness, with a particular focus on issues relevant to the scientific study of consciousness. The first half of this entry (the first to fourth sections) focuses on clarifying the explanandum of a science of consciousness and identifying constraints on an adequate account of consciousness; the second half of this entry (the fifth to seventh sections) examines a number of the methodological challenges facing the science of consciousness.

With all the attention given to the study of consciousness recently, the topic of self-consciousness has been relatively neglected. “It is of course [phenomenal] consciousness rather than...self-conscious that has seemed such a scientific mystery,” a prominent philosopher comments.1 Phenomenal consciousness concerns the aspect of a state that feels a certain way: roses smell like this; garlic tastes like that; middle C sounds like this, and so on. Although phenomenal consciousness is surely a fruitful area of scientific investigation, I hope to demonstrate here that investigation of selfconsciousness offers its own rewards, ontologically speaking.

In this article first some general aspects of near-death experience will be discussed, followed by questions about consciousness and its relation to brain function. Details will be described from our prospective study on near-death experience in survivors of cardiac arrest in the Netherlands, which was published in the Lancet in 2001. In this study it could not be shown that physiological, psychological, or pharmacological factors caused these experiences after cardiac arrest. Neurophysiology in cardiac arrest and in a normal functioning brain will be explained. Finally, implications for consciousness studies will be discussed, and how it could be possible to explain the continuity of our consciousness. Scientific study of NDE pushes us to the limits of our medical and neurophysiologic ideas about the range of human consciousness and mind-brain relation.

Merker suggests that the thalamocortical system is not an essential system for consciousness, but, instead, that the midbrain reticular system is responsible for consciousness. Indeed, the latter is a crucial system for consciousness, when consciousness is regarded as the waking state. However, when consciousness is regarded as phenomenal consciousness, for which experience and perception are essential elements, the thalamocortical system seems to be indispensable.

The relation between subjective consciousness and the physical brain is widely regarded as the last mystery facing science. Papineau argues that consciousness seems mysterious not because of any hidden essence, but only because we think about it in a special way. He exposes the resulting potential for confusion, and shows that much scientific study of consciousness is misconceived.

Brain Mystique Light and Dark bridges the gap between neuroscience, brain evolution and consciousness by examining scientific models of how the brain becomes conscious. The book argues that the spiritual dimension of life is compatible with scientific naturalism. Not bound by conventional stereotypes, Charles Don Keyes safeguards the unity of brain/mind, synthesized from a wide range of sources, reinterprets the triune brain concept and self-reference models of consciousness.

The phenomenon of consciousness has always been a central question for philosophers and scientists. Emerging in the past decade are new approaches to the understanding of consciousness in a scientific light. This book presents a series of essays by leading thinkers giving an account of the current ideas prevalent in the scientific study of consciousness. The value of the book lies in the discussion of this interesting though complex subject from different points of view ranging from physics, computer science to the cognitive sciences. Reviews of controversial ideas related to the philosophy of mind from western and eastern sources including classical Indian first person methodologies provide a breadth of coverage that has seldom been attempted in a book before. Additionally, chapters relating to the new approaches in computational modelling of higher order cognitive function and consciousness are included. The book is of great value for established as well as young researchers from a wide cross-section of interdisciplinary scientific backgrounds, aiming to pursue research in this field, as well as an informed public. * Presents the latest developments in the scientific study of consciousness * Critically reviews different theoretical and philosophical explanations related to the subject * An important book for both students and researchers in designing research projects on consciousness.

Research into consciousness has now become respectable, and much has been written about it. Is consciousness the exclusive property of human beings, or can it be found also in animals? Can machines become conscious? Is consciousness an illusion, and are all mental states ultimately reducible to the movement of molecules? If consciousness is other than matter, what connection does it have with matter? These and others like them are now serious scientific questions in the West. This article discusses consciousness within the frame of the following assertions: Consciousness has evolved from earlier states of awareness to be found in lower forms of life. The current scientific method is too restrictive for the study of conscience and its evolution. In particular classical logic leads scientists to ignore or reject consciousness as a legitimate field of study. Mind and matter, generalized as knowing and being, have equal status.

The subject of consciousness, long shunned by mainstream psychology and the scientific community, has over the last two decades become a legitimate topic of scientific research. One of the most thorough attempts to formulate a theory of consciousness has come from Bernard Baars, a psychologist working at the Wright Institute. Baars proposes that consciousness is the result of a Global Workspace in the brain that distributes information to the huge number of parallel unconscious processors that form the rest of the brain. This paper critiques the central hypothesis of Baars' theory of consciousness.
