Have you ever seen something that wasn’t really there? Heard someone call your name in an empty house? Sensed someone following you and turned around to find nothing? Hallucinations don’t belong wholly to the insane. Much more commonly, they are linked to sensory deprivation, intoxication, illness, or injury. People with migraines may see shimmering arcs of light or tiny, Lilliputian figures of animals and people. People with failing eyesight, paradoxically, may become immersed in a hallucinatory visual world. Hallucinations can be brought on by a simple fever or even the act of waking or falling asleep, when people have visions ranging from luminous blobs of color to beautifully detailed faces or terrifying ogres. Those who are bereaved may receive comforting “visits” from the departed. In some conditions, hallucinations can lead to religious epiphanies or even the feeling of leaving one’s own body. Humans have always sought such life-changing visions, and for thousands of years have used hallucinogenic compounds to achieve them. As a young doctor in California in the 1960s, Oliver Sacks had both a personal and a professional interest in psychedelics. These, along with his early migraine experiences, launched a lifelong investigation into the varieties of hallucinatory experience. Here, with his usual elegance, curiosity, and compassion, Dr. Sacks weaves together stories of his patients and of his own mind-altering experiences to illuminate what hallucinations tell us 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, a vital part of the human condition.

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, the authors 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. 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 receive detailed attention. The authors integrate the wealth of recent findings into a cohesive framework and put forward a comprehensive, multicomponent model of hallucinations. They also discuss the treatment of hallucinations, ranging from pharmacotherapy and cognitive therapy to transcranial magnetic stimulation. The book includes a comprehensive list of available hallucination questionnaires and scales as a handy clinical assessment resource.

The work aims to provide an overview of the field of contemporary hallucinations research. It will consist of 28 chapters, the writing of which will be put out to international experts specialized in the specific fields at hand. The work aims to be unique, in that it intends to cover many different types of hallucination, and to approach the subject matter from four different perspectives, i.e., conceptual, phenomenological, neuroscientific, and therapeutic.

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.

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.

Auditory hallucinations rank amongst the most treatment resistant symptoms of schizophrenia, with command hallucinations being the most distressing, high risk and treatment resistant of all. This new work provides clinicians with a detailed guide, illustrating in depth the techniques and strategies developed for working with command hallucinations. Woven throughout with key cases and clinical examples, Cognitive Therapy for Command Hallucinations clearly demonstrates how these techniques can be applied in a clinical setting. Strategies and solutions for overcoming therapeutic obstacles are shown alongside treatment successes and failures to provide the reader with an accurate understanding of the complexities of cognitive therapy. This helpful and practical guide with be of interest to clinical and forensic psychologists, cognitive behavioural therapists, nurses and psychiatrists.
