Each year, some two million people in the United Kingdom experience visual hallucinations. Infrequent, fleeting visual hallucinations, often around sleep, are a usual feature of life. In contrast, consistent, frequent, persistent hallucinations during waking are strongly associated with clinical disorders; in particular delirium, eye disease, psychosis, and dementia. Research interest in these disorders has driven a rapid expansion in investigatory techniques, new evidence, and explanatory models. In parallel, a move to generative models of normal visual function has resolved the theoretical tension between veridical and hallucinatory perceptions. From initial fragmented areas of investigation, the field has become increasingly coherent over the last decade. Controversies and gaps remain, but for the first time the shapes of possible unifying models are becoming clear, along with the techniques for testing these. This book provides a comprehensive survey of the neuroscience of visual hallucinations and the clinical techniques for testing these. It brings together the very latest evidence from cognitive neuropsychology, neuroimaging, neuropathology, and neuropharmacology, placing this within current models of visual perception. Leading researchers from a range of clinical and basic science areas describe visual hallucinations in their historical and scientific context, combining introductory information with up-to-date discoveries. They discuss results from the main investigatory techniques applied in a range of clinical disorders. The final section outlines future research directions investigating the potential for new understandings of veridical and hallucinatory perceptions, and for treatments of problematic hallucinations. Fully comprehensive, this is an essential reference for clinicians in the fields of the psychology and psychiatry of hallucinations, as well as for researchers in departments, research institutes and libraries. It has strong foundations in neuroscience, cognitive science, optometry, psychiatry, psychology, clinical medicine, and philosophy. With its lucid explanation and many illustrations, it is a clear resource for educators and advanced undergraduate and graduate students.

Hallucinatory phenomena have held the fascination of science since the dawn of medicine, and the popular imagination from the beginning of recorded history. Their study has become a critical aspect of our knowledge of the brain, making significant strides in recent years with advances in neuroimaging, and has established common ground among what normally are regarded as disparate fields. The Neuroscience of Hallucinations synthesizes the most up-to-date findings on these intriguing auditory, visual, olfactory, gustatory, and somatosensory experiences, from their molecular origins to their cognitive expression. In recognition of the wide audience for this information among the neuroscientific, medical, and psychology communities, its editors bring a mature evidence base to highly subjective experience. This knowledge is presented in comprehensive detail as leading researchers across the disciplines ground readers in the basics, offer current cognitive, neurobiological, and computational models of hallucinations, analyze the latest neuroimaging technologies, and discuss emerging interventions, including neuromodulation therapies, new antipsychotic drugs, and integrative programs. Among the topics covered: Hallucinations in the healthy individual. A pathophysiology of transdiagnostic hallucinations including computational and connectivity modeling. Molecular mechanisms of hallucinogenic drugs. Structural and functional variations in the hallucinatory brain in schizophrenia. The neurodevelopment of hallucinations. Innovations in brain stimulation techniques and imaging-guided therapy. Psychiatrists, neurologists, neuropsychologists, cognitive neuroscientists, clinical psychologists, and pharmacologists will welcome The Neuroscience of Hallucinations as a vital guide to the current state and promising future of their shared field.

Visual neuroscience is the study of the way in which the -brain accomplishes sight, and this book presents overviews of a range of topics in this area. The chapters are grouped into six sections - retina, retino-geniculate connections, visual development, comparative visual physiology, visual cortex and integrative aspects - and the authors describe both their own contributions to the field, and the influence of their teacher, P.O. Bishop, on their scientific development.

In einer Zeit des Umbruchs, des fortwährenden Wandels in den Wertvorstellungen, der Zu kunftsängste, aber auch der fortschreitenden Entwicklung der Technik und des planerischen Instrumentariums, in einer solchen Zeit ein Buch über die Grundlagen der Stadtverkehrsplanung herauszugeben, muß als Wagnis bezeichnet werden, das die Verfasser nicht leichtfertig auf sich genommen haben. Sie sind der Auffassung, daß jenseits der vielfältigen, emotional kritischen Diskussionen sowohl die methodischen Grundlagen als auch die praktischen Ansätze einen Standard erreicht haben, der in einem Überblick dargestellt werden sollte. Die Fülle des Stoffes erlaubt kein abschließendes Kompendium. Wichtig erschien den Her ausgebern, daß - neben den allgemeinen Beschreibungen und teilweise auch mit Wertungen ver bundenen zukunftsbezogenen Aussagen - die verschiedenen analytischen, prognostischen und konstruktiv-planerischen Schritte der Verkehrsplanung deutlich gemacht werden. Die Autoren können dabei auf eine umfangreiche Literatur verweisen. Der Praxis stehen zahlreiche Richtli nien und Empfehlungen anerkannter Institutionen (z.B. der Forschungsgesellschaft für Straßen und Verkehrswesen) zur Verfügung, deren flexible Handhabung gerade in Zeiten eines dynami schen Wandels an Bedeutung zunimmt. Die Darstellung beschränkt sich auf die Grundlagen der Planung und des Entwurfs städtischer Verkehrsanlagen und schließt die Behandlung von Themen der Verkehrstheorie, der Verkehrs leittechnik, des Verkehrsmanagements und der Informations- und Kommunikationssysteme aus, da sie den Rahmen dieses Handbuches sprengen würden.

Behavioral Neuroscientists study the behavior of animals and humans and the neurobiological and physiological processes that control it. Behavior is the ultimate function of the nervous system, and the study of it is very multidisciplinary. Disorders of behavior in humans touch millions of people’s lives significantly, and it is of paramount importance to understand pathological conditions such as addictions, anxiety, depression, schizophrenia, autism among others, in order to be able to develop new treatment possibilities. Encyclopedia of Behavioral Neuroscience is the first and only multi-volume reference to comprehensively cover the foundation knowledge in the field. This three volume work is edited by world renowned behavioral neuroscientists George F. Koob, The Scripps Research Institute, Michel Le Moal, Université Bordeaux, and Richard F. Thompson, University of Southern California and written by a premier selection of the leading scientists in their respective fields. Each section is edited by a specialist in the relevant area. The important research in all areas of Behavioral Neuroscience is covered in a total of 210 chapters on topics ranging from neuroethology and learning and memory, to behavioral disorders and psychiatric diseases.

A fascinating cornucopia of new ideas, based on fundamentals of neurobiology, psychology, psychiatry and therapy, this book extends boundaries of current concepts of consciousness. Its eclectic mix will simulate and challenge not only neuroscientists and psychologists but entice others interested in exploring consciousness. Contributions from top researchers in consciousness and related fields project diverse ideas, focused mainly on conscious nonconscious interactions: 1. Paving the way for new research on basic scientific - physiological, pharmacological or neurochemical - mechanisms underpinning conscious experience ( bottom up approach); 2. Providing directions on how psychological processes are involved in consciousness ( top down approach); 3. Indicating how including consciousness could lead to new understanding of mental disorders such as schizophrenia, depression, dementia, and addiction; 4. More provocatively, but still based on scientific evidence, exploring consciousness beyond conventional boundaries, indicating the potential for radical new thinking or quantum leaps in neuroscientific theories of consciousness.

This book provides the first full-length treatment of disjunctivism about visual experiences in the service of defending a naive realist theory of veridical visual perception. It includes detailed theories of hallucination and illusion that show how such states can be indistinguishable from veridical experiences without sharing any common character.
