Book Description
Bálint’s syndrome is named after the Hungarian physician who first reported a remarkable case of a man with complex visuospatial deficits following bilateral lesions within parietal and occipital cortex (Bálint, 1909). The syndrome has three primary symptoms: simultanagnosia (impaired spatial awareness of more than one object at time), optic ataxia (misreaching to visual targets) and ocular apraxia (described by Bálint as “psychic paralysis of gaze”). Balint’s patients not only cannot perceive more than one object at time and therefore show poor comprehension of multi-object visual scenes i.e. poor detection of all the objects present and difficulty in grasping the relationship between them; in addition they typically fail to reach towards location of the single object, which they can perceive. The deficit of the allocation of spatial attention in Balint’s syndrome has been linked to a problem in feature binding which results in illusory conjunctions. Patients with Balint’s syndrome also show deficits in global processing i.e. when integration of multiple local elements into global compound shapes is required. Consequently, Balint’s syndrome provides a unique opportunity to study the nature and neuroanatomy of human visuospatial processing, in particular multi-level object representation, spatial awareness and the distribution of visual attention. The studies collected here cover both the anatomical and the cognitive mechanisms of the different symptoms associated with the syndrome. Furthermore, the dissociations between the components of Bálints’ syndrome, in particular simultanagnosia and optic ataxia, can also co-occur with visual neglect and extinction and the different combinations of reported lesions raises a question about the status of the syndrome and whether it should be merely treated as a historical compilation of symptoms which may or may not coexist cohesively. This interesting argument is raised here.

Book Description
An ancient metaphor likens attention to an archer pulling her bow - the self directing her mind through attention. Yet both the existence of such a self, and the impact of attention on the mind, have been debated for millennia. Advancements in science mean that we now have a better understanding of what attention is and how it works, but philosophers and scientists remain divided as to its impact on the mind. This book takes a strong stance: attention is the key to the self, consciousness, perception, action, and knowledge. While it claims that we cannot perceive novel stimuli without attention, it argues that we can act on and experience the world without attention. It thus provides a new way of thinking about the mind - as something that can either shape itself through attention or engage with the world as it is given, relying on its habits and skills.

Book Description
The second edition of The Neurology of Consciousness is a comprehensive update of this ground-breaking work on human consciousness, the first book in this area to summarize the neuroanatomical and functional underpinnings of consciousness by emphasizing a lesional approach offered by the study of neurological patients. Since the publication of the first edition in 2009, new methodologies have made consciousness much more accessible scientifically, and, in particular, the study of disorders, disruptions, and disturbances of consciousness has added tremendously to our understanding of the biological basis of human consciousness. The publication of a new edition is both critical and timely for continued understanding of the field of consciousness. In this critical and timely update, revised and new contributions by internationally renowned researchers—edited by the leaders in the field of consciousness research—provide a unique and comprehensive focus on human consciousness. The new edition of The Neurobiology of Consciousness will continue to be an indispensable resource for researchers and students working on the cognitive neuroscience of consciousness and related disorders, as well as for neuroscientists, psychologists, psychiatrists, and neurologists contemplating consciousness as one of the philosophical, ethical, sociological, political, and religious questions of our time. - New chapters on the neuroanatomical basis of consciousness and short-term memory, and expanded coverage of comas and neuroethics, including the ethics of brain death - The first comprehensive, authoritative collection to describe disorders of consciousness and how they are used to study and understand the neural correlates of conscious perception in humans. - Includes both revised and new chapters from the top international researchers in the field, including Christof Koch, Marcus Raichle, Nicholas Schiff, Joseph Fins, and Michael Gazzaniga

Book Description
"Locating Consciousness" argues that our qualitative experiences should be aligned with the activity of a single and distinct memory system in our mind/brain. Spelling out in detail what we do and do not know about phenomenological experience, this book denies the common view of consciousness as a central decision-making system. Instead, consciousness is viewed as a lower level dynamical structure underpinning our information processing. This new perspective affords novel solutions to a wide range of problems: the absent qualia, the binding problem, the inverted spectra, the specter of epiphenomenalism, the explanatory gap, the distinction between objective and subjective, and the general skeptical doubts about the viability of the naturalist project itself. Drawing on recent data in psychology and neuroscience, "Locating Consciousness" also discusses when we become conscious and when we should think other animals are conscious. (Series A)

Book Description
Cognition, Brain, and Consciousness, Second Edition, provides students and readers with an overview of the study of the human brain and its cognitive development.It discusses brain molecules and their primary function, which is to help carry brain signals to and from the different parts of the human body. These molecules are also essential for understanding language, learning, perception, thinking, and other cognitive functions of our brain. The book also presents the tools that can be used to view the human brain through brain imaging or recording.New to this edition are Frontiers in Cognitive Neuroscience text boxes, each one focusing on a leading researcher and their topic of expertise. There is a new chapter on Genes and Molecules of Cognition; all other chapters have been thoroughly revised, based on the most recent discoveries.This text is designed for undergraduate and graduate students in Psychology, Neuroscience, and related disciplines in which cognitive neuroscience is taught. - New edition of a very successful textbook - Completely revised to reflect new advances, and feedback from adopters and students - Includes a new chapter on Genes and Molecules of Cognition - Student Solutions available at http://www.baars-gage.com/ For Teachers: - Rapid adoption and course preparation: A wide array of instructor support materials are available online including PowerPoint lecture slides, a test bank with answers, and eFlashcords on key concepts for each chapter. - A textbook with an easy-to-understand thematic approach: in a way that is clear for students from a variety of academic backgrounds, the text introduces concepts such as working memory, selective attention, and social cognition. - A step-by-step guide for introducing students to brain anatomy: color graphics have been carefully selected to illustrate all points and the research explained. Beautifully clear artist's drawings are used to 'build a brain' from top to bottom, simplifying the layout of the brain.
