Book Description
Recent work on perceptual ambiguity and its implications for the correlation between neural events and perceptual experience. Researchers today in neuroscience and cognitive psychology increasingly turn their attention to binocular rivalry and other forms of perceptual ambiguity or bistability. The study of fluctuations in visual perception in the face of unchanging visual input offers a means for understanding the link between neural events and visual events, including visual awareness. Some neuroscientists believe that binocular rivalry reveals a fundamental aspect of human cognition and provides a way to isolate and study brain areas involved in attention and selection. The eighteen essays collected in Binocular Rivalry present the most recent theoretical and empirical work on this key topic by leading researchers in the field. After the opening chapter's overview of the major characteristics of binocular rivalry in their historical contexts, the contributors consider topics ranging from the basic phenomenon of perceptual ambiguity to brain models and neural networks. The essays illustrate the potential power of the study of perceptual ambiguity as a tool for learning about the neural concomitants of visual awareness, or, as they have been called, the "neural correlates of consciousness."

Book Description
Brain-mind problems like consciousness have been stimulating the interest of philosophers and scientists since the ancient times. In the last decades, the dramatic development of neuroscience has allowed studying such phenomena at several different levels – from single neurons to behavior. Binocular rivalry, a paradigm dissociating the sensory input from the conscious perception during dichoptic viewing of incongruent images, has been a celebrated example of such a tool. During the last century, empirical research on binocular rivalry contributed the first important insights into the neuronal mechanisms of subjective visual perception. Recent advances in brain imaging and electrophysiological recording/stimulating techniques as well as novel theoretical concepts and analytical methods could be exploited to expand our knowledge on this fascinating phenomenon of visual perception and elucidate the neural processes underlying visual consciousness. This Research Topic aims to bring together contributions that could expand the current frontiers of knowledge in binocular rivalry. In particular we would like to focus on reviews, hypothesis & theory or original research articles that specifically combine novel concepts, analytical tools and neurophysiological techniques with binocular rivalry. We expect that these contributions will a) integrate the vast knowledge already existing in the field b) formulate and, when possible, address questions under the light of recent methodological advances in neuroscience and c) provide a benchmark that will stimulate future cutting edge research.

Book Description
Binocular vision, i.e. where both eyes are used together, is a fundamental component of human sight. It also aids hand-eye co-ordination, and the perception of the self within the environment. Clinical anomalies pose a wide range of problems to the sufferer, but normal binocular operation must first be understood before the eye specialist can assess and treat dysfunctions. This is a major new textbook for students of optometry, orthoptics and ophthalmology, and also of psychology. Chapters span such key topics as binocular summation, fusion, the normal horopter, anatomy of the extra-ocular muscles, oculomotor control, binocular integration and depth perception. Fully illustrated throughout, the book includes self-assessment exercises at the end of each chapter, and sample experiments in binocular vision functioning.

Book Description
Our ability to be conscious of the world around us is often discussed as one of the most amazing yet enigmatic processes under scientific investigation today. However, our ability to imagine the world around us in the absence of stimulation from that world is perhaps even more amazing. This capacity to experience objects or scenarios through imagination, that do not necessarily exist in the world, is perhaps one of the fundamental abilities that allows us successfully to think about, plan, run a dress rehearsal of future events, re-analyze past events and even simulate or fantasize abstract events that may never happen. Empirical research into mental imagery has seen a recent surge, due partly to the development of new neuroscientifc methods and their clever application, but also due to the increasing discovery and application of more objective methods to investigate this inherently internal and private process. As the topic is cross hosted in Frontiers in Perception Science and Frontiers in Human Neuroscience, we invite researchers from different fields to submit opinionated but balanced reviews, new empirical, theoretical, philosophical or technical papers covering any aspect of mental imagery. In particular, we encourage submissions focusing on different sensory modalities, such as olfaction, audition somatosensory etc. Similarly, we support submissions focusing on the relationship between mental imagery and other neural and cognitive functions or disorders such as visual working memory, visual search or disorders of anxiety. Together, we hope that collecting a group of papers on this research topic will help to unify theory while providing an overview of the state of the field, where it is heading, and how mental imagery relates to other cognitive and sensory functions.

Book Description
This book brings together an international group of neuroscientists and philosophers who are investigating how the content of subjective experience is correlated with events in the brain. The fundamental methodological problem in consciousness research is the subjectivity of the target phenomenon--the fact that conscious experience, under standard conditions, is always tied to an individual, first-person perspective. The core empirical question is whether and how physical states of the human nervous system can be mapped onto the content of conscious experience. The search for the neural correlates of consciousness (NCC) has become a highly active field of investigation in recent years. Methods such as single-cell recording in monkeys and brain imaging and electrophysiology in humans, applied to such phenomena as blindsight, implicit/explicit cognition, and binocular rivalry, have generated a wealth of data. The same period has seen the development of a number of theories about NCC location. This volume brings together the leading experimentalists and theoreticians in the field. Topics include foundational and evolutionary issues, global integration, vision, consciousness and the NMDA receptor complex, neuroimaging, implicit processes, intentionality and phenomenal volition, schizophrenia, social cognition, and the phenomenal self.

Book Description
A fascinating exploration of the human brain that combines “the leading edge of consciousness science with surprisingly personal and philosophical reflection . . . shedding light on how scientists really think”—this is “science writing at its best” (Times Higher Education). In which a scientist searches for an empirical explanation for phenomenal experience, spurred by his instinctual belief that life is meaningful. What links conscious experience of pain, joy, color, and smell to bioelectrical activity in the brain? How can anything physical give rise to nonphysical, subjective, conscious states? Christof Koch has devoted much of his career to bridging the seemingly unbridgeable gap between the physics of the brain and phenomenal experience. This engaging book—part scientific overview, part memoir, part futurist speculation—describes Koch’s search for an empirical explanation for consciousness. Koch recounts not only the birth of the modern science of consciousness but also the subterranean motivation for his quest—his instinctual (if “romantic”) belief that life is meaningful. Koch describes his own groundbreaking work with Francis Crick in the 1990s and 2000s and the gradual emergence of consciousness (once considered a “fringy” subject) as a legitimate topic for scientific investigation. Present at this paradigm shift were Koch and a handful of colleagues, including Ned Block, David Chalmers, Stanislas Dehaene, Giulio Tononi, Wolf Singer, and others. Aiding and abetting it were new techniques to listen in on the activity of individual nerve cells, clinical studies, and brain-imaging technologies that allowed safe and noninvasive study of the human brain in action. Koch gives us stories from the front lines of modern research into the neurobiology of consciousness as well as his own reflections on a variety of topics, including the distinction between attention and awareness, the unconscious, how neurons respond to Homer Simpson, the physics and biology of free will, dogs, Der Ring des Nibelungen, sentient machines, the loss of his belief in a personal God, and sadness. All of them are signposts in the pursuit of his life's work—to uncover the roots of consciousness.
