Описание: Each year, some two million people in the United Kingdomexperience visual hallucinations. Infrequent, fleeting visualhallucinations, often around sleep, are a usual feature of life. Incontrast, consistent, frequent, persistent hallucinations duringwaking are strongly associated with clinical disorders; inparticular delirium, eye disease, psychosis, and dementia. Researchinterest in these disorders has driven a rapid expansion ininvestigatory techniques, new evidence, and explanatory models. Inparallel, a move to generative models of normal visual function hasresolved the theoretical tension between veridical andhallucinatory perceptions. From initial fragmented areas ofinvestigation, the field has become increasingly coherent over thelast decade. Controversies and gaps remain, but for the first timethe shapes of possible unifying models are becoming clear, alongwith the techniques for testing these. This book provides a comprehensive survey of the neuroscience ofvisual hallucinations and the clinical techniques for testingthese. It brings together the very latest evidence from cognitiveneuropsychology, neuroimaging, neuropathology, andneuropharmacology, placing this within current models of visualperception. Leading researchers from a range of clinical and basic scienceareas describe visual hallucinations in their historical andscientific context, combining introductory information withup–to–date discoveries. They discuss results from the maininvestigatory techniques applied in a range of clinical disorders.The final section outlines future research directions investigatingthe potential for new understandings of veridical and hallucinatoryperceptions, and for treatments of problematic hallucinations. Fully comprehensive, this is an essential reference forclinicians in the fields of the psychology and psychiatry ofhallucinations, as well as for researchers in departments, researchinstitutes and libraries. It has strong foundations inneuroscience, cognitive science, optometry, psychiatry, psychology,clinical medicine, and philosophy. With its lucid explanation andmany illustrations, it is a clear resource for educators andadvanced undergraduate and graduate students.

Описание: 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.
Описание: Hallucinations are a troublesome and distressing symptom for countless patients who suffer from psychiatric or neurological conditions. This book brings together the work of leading experts in this area, to provide a practical guide to the assessment, evaluation, and treatment of hallucinations.
