The Neuroscience of Visual Hallucinations by Daniel Collerton Pdf

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.

The Neuroscience of Hallucinations by Renaud Jardri,Arnaud Cachia,Pierre Thomas,Delphine Pins Pdf

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.

Hallucinations by Oliver Sacks Pdf

NATIONAL BESTSELLER • The "poet laureate of medicine" (The New York Times) and author of The Man Who Mistook His Wife for a Hat weaves together stories of mind-altering experiences to reveal what they tell us about our brains, our folklore and culture, and why the potential for hallucination exists in us all. “An absorbing plunge into a mystery of the mind.” —Entertainment Weekly To many people, hallucinations imply madness, but in fact they are a common part of the human experience. These sensory distortions range from the shimmering zigzags of a visual migraine to powerful visions brought on by fever, injuries, drugs, sensory deprivation, exhaustion, or even grief. Hallucinations doubtless lie behind many mythological traditions, literary inventions, and religious epiphanies. Drawing on his own experiences, a wealth of clinical cases from among his patients, and famous historical examples ranging from Dostoevsky to Lewis Carroll, the legendary neurologist Oliver Sacks investigates the mystery of these sensory deceptions: what they say about the working of our brains, how they have influenced our folklore and culture, and why the potential for hallucination is present in all humans.

Hallucinations by Oliver Sacks Pdf

Hallucinations, for most people, imply madness. But there are many different types of non-psychotic hallucination caused by various illnesses or injuries, by intoxication--even, for many people, by falling sleep. From the elementary geometrical shapes that we see when we rub our eyes to the complex swirls and blind spots and zigzags of a visual migraine, hallucination takes many forms. At a higher level, hallucinations associated with the altered states of consciousness that may come with sensory deprivation or certain brain disorders can lead to religious epiphanies or conversions. Drawing on a wealth of clinical examples from his own patients as well as historical and literary descriptions, Oliver Sacks investigates the fundamental differences and similarities of these many sorts of hallucinations, what they say about the organization and structure of our brains, how they have influenced every culture's folklore and art, and why the potential for hallucination is present in us all.

Hallucination by Fiona Macpherson,Dimitris Platchias Pdf

Scientific and philosophical perspectives on hallucination: essays that draw on empirical evidence from psychology, neuroscience, and cutting-edge philosophical theory. Reflection on the nature of hallucination has relevance for many traditional philosophical debates concerning the nature of the mind, perception, and our knowledge of the world. In recent years, neuroimaging techniques and scientific findings on the nature of hallucination, combined with interest in new philosophical theories of perception such as disjunctivism, have brought the topic of hallucination once more to the forefront of philosophical thinking. Scientific evidence from psychology, neuroscience, and psychiatry sheds light on the functional role and physiology of actual hallucinations; some disjunctivist theories offer a radically new and different philosophical conception of hallucination. This volume offers interdisciplinary perspectives on the nature of hallucination, offering essays by both scientists and philosophers. Contributors first consider topics from psychology and neuroscience, including neurobiological mechanisms of hallucination and the nature and phenomenology of auditory-verbal hallucinations. Philosophical discussions follow, with contributors first considering disjunctivism and then, more generally, the relation between hallucination and the nature of experience.

New Horizons in the Neuroscience of Consciousness by Elaine K. Perry,Daniel Collerton,Fiona E.N. LeBeau,Heather Ashton Pdf

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.

A History of Neuropsychology by J. Bogousslavsky,F. Boller,M. Iwata Pdf

Neuropsychology has become a very important aspect for neurologists in clinical practice as well as in research. Being a specialized field in psychology, its long history is based on different historical developments in brain science and clinical neurology. In this volume, we want to show how present concepts of neuropsychology originated and were established by outlining the most important developments since the end of the 19th century. The articles of this book that cover topics such as aphasia, amnesia and dementia show a great multicultural influence due to an editorship and authorship that spans all developmental initiatives in Europe, Asia, and America. This book gives a better understanding of the development of higher brain function studies and is an interesting read for neurologists, psychiatrists, psychologists, neurosurgeons, historians, and anyone else interested in the history of neuropsychology.

Hallucinations by André Aleman,Frank Larøi Pdf

"Hearing voices when nobody speaks or seeing objects no one else sees--hallucinations are intriguing phenomena that have puzzled clinicians, researchers, and lay people alike for centuries. In this book, authors Andr Aleman and Frank Laroi review the latest research on the cognitive and neural bases of hallucinations and outline their unique neurobiology by drawing on evidence from brain imaging and neurotransmission studies. Detailed attention is paid to hallucination characteristics in different forms of psychosis as well as other clinical groups and conditions, such as brain damage, Charles Bonnet syndrome, dementia, and chemical substance abuse. The authors integrate the wealth of recent findings into a cohesive framework and put forward a comprehensive, multicomponent model of hallucinations. They also explore treatment of hallucinations, ranging from pharmacotherapy and cognitive therapy to transcranial magnetic stimulation. A comprehensive list of available hallucination questionnaires and scales is also included as a handy clinical assessment resource"--Jacket.
