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.

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.

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.

Experiences of hearing the voice of God (or angels, demons, or other spiritual beings) have generally been understood either as religious experiences or else as a feature of mental illness. Some critics of traditional religious faith have dismissed the visions and voices attributed to biblical characters and saints as evidence of mental disorder. However, it is now known that many ordinary people, with no other evidence of mental disorder, also hear voices and that these voices not infrequently include spiritual or religious content. Psychological and interdisciplinary research has shed a revealing light on these experiences in recent years, so that we now know much more about the phenomenon of "hearing voices" than ever before. The present work considers biblical, historical, and scientific accounts of spiritual and mystical experiences of voice hearing in the Christian tradition in order to explore how some voices may be understood theologically as revelatory. It is proposed that in the incarnation, Christian faith finds both an understanding of what it is to be fully human (a theological anthropology), and God’s perfect self-disclosure (revelation). Within such an understanding, revelatory voices represent a key point of interpersonal encounter between human beings and God.

"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.

The first authoritative review on the parasomnias - disorders that cause abnormal behavior during sleep - this book contains many topics never before covered in detail. The behaviors associated with parasomnias may lead to injury of the patient or bed-partner, and may have forensic implications. These phenomena are common but often unrecognized, misdiagnosed, or ignored in clinical practice. With increasing awareness of abnormal behaviors in sleep, the book fulfils the need for in-depth descriptions of clinical and research aspects of these disorders, including differential diagnosis, pathophysiology, morbidity, and functional consequences of each condition, where known. Appropriate behavioral and pharmacological treatments are addressed in detail. There are authoritative sections on disorders of arousal, parasomnias usually associated with REM sleep, sleep-related movement disorders and other variants, and therapy of parasomnias. Sleep specialists, neurologists, psychiatrists, psychologists and other healthcare professionals with an interest in sleep disorders will find this book essential reading.
