Book excerpt: 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."

Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: WINNER OF THE 2014 BRAIN PRIZE From the acclaimed author of Reading in the Brain and How We Learn, a breathtaking look at the new science that can track consciousness deep in the brain How does our brain generate a conscious thought? And why does so much of our knowledge remain unconscious? Thanks to clever psychological and brain-imaging experiments, scientists are closer to cracking this mystery than ever before. In this lively book, Stanislas Dehaene describes the pioneering work his lab and the labs of other cognitive neuroscientists worldwide have accomplished in defining, testing, and explaining the brain events behind a conscious state. We can now pin down the neurons that fire when a person reports becoming aware of a piece of information and understand the crucial role unconscious computations play in how we make decisions. The emerging theory enables a test of consciousness in animals, babies, and those with severe brain injuries. A joyous exploration of the mind and its thrilling complexities, Consciousness and the Brain will excite anyone interested in cutting-edge science and technology and the vast philosophical, personal, and ethical implications of finally quantifying consciousness.
Download or read book Investigating the Role of M and P Pathways in the Human Brain During Binocular Rivalry written by Irem Yildirim and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: When two sufficiently different stimuli are presented to each eye, perception alternates between them. Known as binocular rivalry, it is an example where visual consciousness needs to resolve a competition. Here, I aimed at investigating the neural mechanism behind this phenomenon, focusing on the contribution of the two visual pathways. Magnocellular (M) and Parvocellular (P) pathways are two information processing streams whose functions have been informative to explain many visual phenomena and clinical disorders. In the lateral geniculate nucleus (LGN), the M and P neurons are disjoint in a layered structure, receiving input from a single eye. Using magnetic resonance imaging (MRI), my goal was to identify the M and P layers in the LGN and examine the rivalry-related eye-specific responses within these layers. Series of techniques and analyses revealed that quantitative MRI is promising to identify the M and P layers in the LGN while functional MRI with monocular eye stimulation results in a clustered eye-specific structure and is not useful to separate the eye- specific regions into M and P sections. However, unsupervised approximation of the data with non-negative matrix factorization provided more consistent eye-specific structure than the generalized linear model. In the investigation of binocular rivalry, achromatic gratings induced rivalry that was represented in the eye-specific layers, and overall rivalry magnitude was similar in the M and P sections. These results highlight the importance of design and analysis in the functional imaging of the LGN layers and contributes to the binocular rivalry literature by showing the perceptual resolution in the LGN with achromatic stimuli and within M and P sections.
Download or read book Neural Correlates of Consciousness written by Thomas Metzinger and published by MIT Press. This book was released on 2000 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Visual Perception written by Tom Cornsweet and published by Academic Press. This book was released on 2012-12-02 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual Perception explores fundamental topics underlying the field of visual perception, including the perception of brightness and color, the physics of light, and the optics of the eye. Although the text leans heavily on physical and physiological concepts, explanations of the relevant physics and physiology are considered. This book is organized into 16 chapters and begins with an overview of the relationship between information assimilation and the physiology of the visual system based on data gathered both in physiological and perceptual experiments. More specifically, this text discusses the nature of the human perceptual system in terms of the kinds of information that are assimilated from the world, and how this selection of information is governed by the structure of receptors and the neural circuits that are connected to them. The relationships between symbols and their corresponding physical and physiological variables are also examined. Finally, the book addresses the presence of strong lateral inhibition in the visual system and how it fits the concept of evolution. This book is aimed at undergraduate and graduate students, regardless of their academic backgrounds.
Download or read book Fixing My Gaze written by Susan R. Barry and published by Basic Books. This book was released on 2009-05-26 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: A revelatory account of the brain's capacity for change When neuroscientist Susan Barry was fifty years old, she experienced the sense of immersion in a three dimensional world for the first time. Skyscrapers on street corners appeared to loom out toward her like the bows of giant ships. Tree branches projected upward and outward, enclosing and commanding palpable volumes of space. Leaves created intricate mosaics in 3D. Barry had been cross-eyed and stereoblind since early infancy. After half a century of perceiving her surroundings as flat and compressed, on that day she saw the city of Manhattan in stereo depth for first time in her life. As a neuroscientist, she understood just how extraordinary this transformation was, not only for herself but for the scientific understanding of the human brain. Scientists have long believed that the brain is malleable only during a "critical period" in early childhood. According to this theory, Barry's brain had organized itself when she was a baby to avoid double vision - and there was no way to rewire it as an adult. But Barry found an optometrist who prescribed a little-known program of vision therapy; after intensive training, Barry was ultimately able to accomplish what other scientists and even she herself had once considered impossible. Dubbed "Stereo Sue" by renowned neurologist Oliver Sacks, Susan Barry tells her own remarkable journey and celebrates the joyous pleasure of our senses.
Download or read book Cognition and Emotion written by Eric Eich and published by Oxford University Press. This book was released on 2000-08-24 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have witnessed a revival of research in the interplay between cognition and emotion. The reasons for this renaissance are many and varied. In the first place, emotion theorists have come to recognize the pivotal role of cognitive factors in virtually all aspects of the emotion process, and to rely on basic cognitive factors and insight in creating new models of affective space. Also, the successful application of cognitive therapies to affective disorders has prompted clinical psychologists to work towards a clearer understanding of the connections between cognitive processes and emotional problems. And whereas the cognitive revolutionaries of the 1960s regarded emotions with suspicion, viewing them as nagging sources of "hot" noise in an otherwise cool, rational, and computer-like system of information processing, cognitive researchers of the 1990s regard emotions with respect, owing to their potent and predictable effects on tasks as diverse as object perception, episodic recall, and risk assessment. These intersecting lines of interest have made cognition and emotion one of the most active and rapidly developing areas within psychological science. Written in debate format, this book covers developing fields such as social cognition, as well as classic areas such as memory, learning, perception and categorization. The links between emotion and memory, learning, perception, categorization, social judgements, and behavior are addressed. Contributors come from the U.S., Canada, Australia, and France.
