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.

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. 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. In Hallucinations, with his usual elegance, curiosity, and compassion, Dr Oliver 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.

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.

Hallucinations, a natural phenomenon as old as mankind, have a surprisingly wide range. They appear under the most diversified conditions, in the "normal" psyche as well as in severe chronic mental derangement. As a symptom, hallucinations are a potential part of a variety of pathological conditions in almost all kinds of psychotic behavior. In addition, lately, various psychological and sociological circumstances seem to favor widespread use and abuse of hallucinogens, substances able to produce hallucinations in the normal brain. They not rarely lead to serious psychopatho logy such as toxic, and mobilized or aggravated endogenous psycho ses. While such development adds to our scientific knowledge, it also contributes to our current social troubles. Neurologists and neuro-surgeons, psychiatrists, psychologists and other specialized researchers constantly have been dealing with the phenomenon, its roots and branches, and yet, its primary mechanisms are largely un known. However, investigators of hallucinations now seem to enter common ground on which meaningful discussions and joint approaches become feasible and more promising. We have come a long way from the Latin term "hallucinari", meaning to talk nonsense, to be absent-minded, to the modern con cept of "hallucinations". While the Latin word was descriptive of what may be due to hallucinations, the modern concept defines hal lucinations as subjective experiences that are consequences of men tal processes, sometimes fulfilling a purpose in the individual's mental life.

The Dictionary of Hallucinations is an alphabetical listing of issues pertaining to hallucinations and other misperceptions. They can be roughly divided into five categories: 1. Definitions of individual hallucinatory symptoms 2. Medical conditions and substances associated with the mediation of hallucinations 3. Definitions of the terms hallucination and illusion by important historical authors 4. Historical figures who are known to have experienced hallucinations 5. Miscellaneous issues. Each of the definitions of individual hallucinatory symptoms includes: a definition of the term its etymological origin the year of introduction (if known) a reference to the author or authors who introduced the term (if known) a description of the current use a brief explanation of the etiology and pathophysiology of the symptom at hand (if known) references to related terms references to the literature. Jan Dirk Blom, M.D., Ph.D., is a clinical psychiatrist, specializing in the field of psychotic disorders. He holds a Ph.D. from the Philosophy Department of the University of Leiden, on the deconstruction of the biomedical schizophrenia concept. He is currently involved in a collaborative project with the University of Utrecht, on model based and model free analyses of fMRI activation patterns obtained from individuals with verbal auditory hallucinations, and an experimental treatment method with fMRI-guided repetitive transcranial magnetic stimulation.

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.

Im Jahre 1971 macht sich eine Gruppe junger amerikanischer Anthropologen und Botaniker auf ins Amazonasgebiet, um die Wirkung von halluzinogenen Pflanzen auf das Weltbild der eingeborenen Schamanen zu erforschen. Die Einnahme dort wachsender Psilocybin-Pilze versetzt zwei von ihnen, Terence McKenna und seinen Bruder Dennis, selbst in den Zustand, den sie an visionssuchenden Schamanen untersuchen wollten. Dieses Erlebnis überzeugte McKenna, dass die Welt der ekstatischen Trance des Schamanen, die visionäre Welt des Psilocybins und die Welt, in der man Ausserirdische antrifft, verschiedene Aspekte ein und derselben paradoxen Realität sind. In den Jahren danach festigte sich seine Ansicht, dass man Psilocybin dazu benutzen kann, das Verhältnis von Geist und dem Unbekannten zu erforschen. Als Forscher einer neuen Generation erkundete er die nicht rationalen Teile der Psyche und entwickelte mit Hilfe seiner rationalen wissenschaftlichen Ausbildung eine "Quantenpsychologie". Sein Buch liest sich so spannend wie ein Bericht über die Erkundung eines fremden Kontinents.
