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.

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.

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.

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.

Tex[t]-Mex

Seductive Hallucinations of the "Mexican" in America

“Marvels! Rompecabezas! And cartoons that bite into the mind appear throughout this long-awaited book that promises to reshape and refocus how we see Mexicans in the Americas and how we are taught and seduced to mis/understand our human potentials for solidarity. This is the closest [email protected] studies has come to a revolutionary vision of how American culture works through its image machines, a vision that cuts through to the roots of the U.S. propaganda archive on Mexican, Tex-Mex, Latino, Chicano/a humanity. Nericcio exposes, deciphers, historicizes, and 'cuts-up' the postcards, movies, captions, poems, and adverts that plaster dehumanization (he calls them 'miscegenated semantic oddities') through our brains. For him, understanding the sweet and sour hallucinations is not enough. He wants the flashing waters of our critical education to become instruments of restoration. In this book, Walter Benjamin meets Italo Calvino and they morph into Nericcio. Orale! -Davíd Carrasco, Harvard University A rogues' gallery of Mexican bandits, bombshells, lotharios, and thieves saturates American popular culture. Remember Speedy Gonzalez? “Mexican Spitfire” Lupe Vélez? The Frito Bandito? Familiar and reassuring-at least to Anglos-these Mexican stereotypes are not a people but a text, a carefully woven, articulated, and consumer-ready commodity. In this original, provocative, and highly entertaining book, William Anthony Nericcio deconstructs Tex[t]-Mexicans in films, television, advertising, comic books, toys, literature, and even critical theory, revealing them to be less flesh-and-blood than “seductive hallucinations,” less reality than consumer products, a kind of “digital crack.” Nericcio engages in close readings of rogue/icons Rita Hayworth, Speedy Gonzalez, Lupe Vélez, and Frida Kahlo, as well as Orson Welles' film Touch of Evil and the comic artistry of Gilbert Hernandez. He playfully yet devastatingly discloses how American cultural creators have invented and used these and other Tex[t]-Mexicans since the Mexican Revolution of 1910, thereby exposing the stereotypes, agendas, phobias, and intellectual deceits that drive American popular culture. This sophisticated, innovative history of celebrity Latina/o mannequins in the American marketplace takes a quantum leap toward a constructive and deconstructive next-generation figuration/adoration of Latinos in America.

Filled with impassioned logic and musicality, John Sibley Williams' debut collection strives to control the uncontrollable by redefining the method of approach. In these compact poems, so edged in dark corners and the strenuous songs of beauty and identity, Williams establishes a unique world of contradictions and connections that bridge the foreign and the familiar. Moving through art and history, through apocalyptic visions and family, into and back out of the paradox of using language to express languagelessness, Controlled Hallucinations weaves universal themes and images with the basic human reality of touch, word, and what is lost in their translation.

Voices of Reason, Voices of Insanity

Studies of Verbal Hallucinations

Records of people experiencing verbal hallucinations or 'hearing voices' can be found throughout history. Voices of Reason, Voices of Insanity examines almost 2,800 years of these reports including Socrates, Schreber and Pierre Janet's "Marcelle", to provide a clear understanding of the experience and how it may have changed over the millenia. Through six cases of historical and contemporary voice hearers, Leudar and Thomas demonstrate how the experience has metamorphosed from being a sign of virtue to a sign of insanity, signalling such illnesses as schizophrenia or dissociation. They argue that the experience is interpreted by the voice hearer according to social categories conveyed through language, and is therefore best studied as a matter of language use. Controversially, they conclude that 'hearing voices' is an ordinary human experience which is unfortunately either mystified or pathologised. Voices of Reason, Voices of Insanity offers a fresh perspective on this enigmatic experience and will be of interest to students, researchers and clinicians alike.

Like The Man Who Mistook His Wife for a Hat, this is a fascinating voyage into a strange and wonderful land, a provocative meditation on communication, biology, adaptation, and culture. In Seeing Voices, Oliver Sacks turns his attention to the subject of deafness, and the result is a deeply felt portrait of a minority struggling for recognition and respect--a minority with its own rich, sometimes astonishing, culture and unique visual language, an extraordinary mode of communication that tells us much about the basis of language in hearing people as well. Seeing Voices is, as Studs Terkel has written, "an exquisite, as well as revelatory, work."
