The idea of a disjunctive theory of visual experiences first found expression in J.M. Hinton's pioneering 1973 book Experiences. In the first monograph in this exciting area since then, William Fish develops a comprehensive disjunctive theory, incorporating detailed accounts of the three core kinds of visual experience--perception, hallucination, and illusion--and an explanation of how perception and hallucination could be indiscriminable from one another without having anything in common. In the veridical case, Fish contends that the perception of a particular state of affairs involves the subject's being acquainted with that state of affairs, and that it is the subject's standing in this acquaintance relation that makes the experience possess a phenomenal character. Fish argues that when we hallucinate, we are having an experience that, while lacking phenomenal character, is mistakenly supposed by the subject to possess it. Fish then shows how this approach to visual experience is compatible with empirical research into the workings of the brain and concludes by extending this treatment to cover the many different types of illusion that we can be subject to.

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.

Psychotic Disorders: Comprehensive Conceptualization and Treatments emphasizes a dimensional approach to psychosis--one of the most fascinating manifestations of altered brain behavior--that cuts across a broad array of psychiatric diagnoses from schizophrenia to affective psychosis and organic disorders like epilepsy and dementias. Written by an international roster of over seventy leading experts in the field, this volume comprehensively reviews, critiques, and integrates available knowledge on the etiology, mechanisms, and treatments of psychotic disorders, and outlines ways forward in both research and clinical practice towards more objective, mechanistically-based definitions of psychotic disorders. Chapters address topics such as psychosis phenomenology, biomarkers and treatments, the overlaps and interfaces between psychiatric disorders within the psychosis dimension, and novel disease definitions. Furthermore, the volume incorporates findings on potential mechanisms, bridges between various system levels (i.e., genetic, epigenetic, molecular and cellular, brain circuit and function, psychological, social, environmental and cultural) and their interactions, as well as the potential role in causation and/or mediation in psychotic disorders. Finally, the volume outlines a broad array of treatment approaches, from the readily available (e.g., psychopharmacology, various modalities of psychotherapy) to the experimental (e.g., cognitive interventions, neuromodulation). With a concluding section of forward perspectives conjecturing future directions and related challenges, this book aspires to stimulate new knowledge, generate novel frameworks, and carry new directions forward on psychotic disorders.

In this ground-breaking synthesis of art and science, Diana Deutsch, one of the world's leading experts on the psychology of music, shows how illusions of music and speech--many of which she herself discovered--have fundamentally altered thinking about the brain. These astonishing illusions show that people can differ strikingly in how they hear musical patterns--differences that reflect variations in brain organization as well as influences of language on music perception. Drawing on a wide variety of fields, including psychology, music theory, linguistics, and neuroscience, Deutsch examines questions such as: When an orchestra performs a symphony, what is the "real" music? Is it in the mind of the composer, or the conductor, or different members of the audience? Deutsch also explores extremes of musical ability, and other surprising responses to music and speech. Why is perfect pitch so rare? Why do some people hallucinate music or speech? Why do we hear phantom words and phrases? Why are we subject to stuck tunes, or "earworms"? Why do we hear a spoken phrase as sung just because it is presented repeatedly? In evaluating these questions, she also shows how music and speech are intertwined, and argues that they stem from an early form of communication that had elements of both. Many of the illusions described in the book are so striking and paradoxical that you need to hear them to believe them. The book enables you to listen to the sounds that are described while reading about them.

Migraine Art includes more than 300 powerful illustrations and paintings created by migraine sufferers from around the world. It provides a thoroughly unique window into the subjective world of the migraine sufferer. The idea of collecting migraine art started with a number of public competitions in the 1980s, which encouraged artists, both amateur and professional, to illustrate the pain, the visual disturbances, and the effect migraines had on their lives. The book includes hundreds of these submissions as well as detailed descriptions of different types of migraine visual phenomena. Covering such topics as migraine signs, triggers, and treatments, as well as types of visual hallucinations and somatic sensations and experiences, the book offers a comprehensive view of the migraine experience. Each category of visual disturbance is accompanied by related artwork. A description of migraine visual experiences of famous historical figures, such as Blaise Pascal and Lewis Carroll, provide historical background on the topic. The book also includes a history of four Migraine Art competitions and information about the Migraine Art collection.
