Hallucinations

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.

  • "Charles Bonnet, naturalista ginevrino del Settecento, si era occupato di tutto: dall'entomologia alla riproduzione dei polpi, dalla botanica alla filosofia. Quando seppe che suo nonno, ormai semicieco, iniziava ad avere <<visioni>> di strani oggetti flottanti e di ospiti immaginari, volle stenderne un minuzioso resoconto, che passò inosservato per oltre un secolo e mezzo. Oggi la sindrome descritta da Charles Bonnet, che collegava l'insorgere di stati allucinatori con la regressione della vista come se il cervello intervenisse, a modo suo, per compensare il senso perduto, è ormai riconosciuta dalla letteratura medica, anche se viene raramente diagnosticata perché le allucinazioni sono associate alla demenza, alla psicosi, e chi ne soffre tende spesso a tacerne. Ma non è sempre stato così: in altri tempi e in altre culture, gli stati alterati di coscienza venivano percepiti come condizione privilegiata da ricercare e indurre con la meditazione, l'ascesi, le droghe e hanno influenzato l'arte, il folclore, il senso del divino. Con questa <<storia naturale delle allucinazioni>> Sacks aggiunge un ulteriore tassello alla sua <<scienza romantica>>, capace di tramutare la casistica medica in una forma d'arte empatica. E prosegue il racconto autobiografico avviato con Zio Tungsteno: dopo l'infanzia, scopriamo così la giovinezza del neurologo più famoso del mondo, trascorsa sulle spiagge della California e costellata di azzardate sperimentazioni psicotrope. Allucinazioni olfattive, uditive, tattili, spaziali, arti fantasma, Doppelgänger, epifanie mistiche, squilibri chimici: ogni argomento viene affrontato con la consueta capacità di immedesimazione, con curiosità ed eleganza innate, e analizzato sotto le lenti della ricerca specialistica, della letteratura e dell'esperienza clinica e personale di Sacks."

  • "This book is an investigation into the types, physiological sources, and cultural resonances of hallucinations traces everything from the disorientations of sleep and intoxication to the manifestations of injury and illness. Have you ever seen something that was not 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, the author 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, he 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."@en
