La Hora de la Fenomenología en la Esquizofrenia

Clínica y Salud 2010 Pérez-Álvarez Marino, M. García-Montes José, Sass Louis 19 citations

This study describes the contributions that phenomenology can make to our understanding of schizophrenia. It begins by showing that phenomenology is recovering the psychopathological tradition lost after the success of the DSM-III and the establishment of neurobiology as the dominant approach. Its contributions are described in three parts: its conceptualization, evaluation and treatment of...

Consciousness and Society: Societal Aspects and Implications of Transpersonal Psychology

International Journal of Transpersonal Studies 2010 Harry T. Hunt 9 citations

Although transpersonal psychologies of self realization emphasize individual development, earlier shamanic traditions also showed a central societal aspect and group based consciousness. Indeed, many have understood the transpersonal movement as developing towards an abstract globalized neo-shamanism. That altered states of consciousness, whether as integrative realizations of the numinous or...

'A man can be destroyed but not defeated': Ernest Hemingway's near-death experience and declining health.

Frontiers of neurology and neuroscience 2010 Sebastian Dieguez

Ernest Hemingway is one of the most popular and widely acclaimed American writers of the 20th century. His works and life epitomize the image of the hyper-masculine hero, facing the cruelties of life with 'grace under pressure'. Most of his writings have a quasi-autobiographical quality, which allowed many commentators to draw comparisons between his personality and his art. Here, we examine...

The persistence of the subjective in neuropsychopharmacology: observations of contemporary hallucinogen research.

History of the Human Sciences 2010 Nicolas Langlitz 32 citations

The elimination of subjectivity through brain research and the replacement of so-called "folk psychology" by a neuroscientifically enlightened worldview and self-conception has been both hoped for and feared. But this cultural revolution is still pending. Based on nine months of fieldwork on the revival of hallucinogen research since the "Decade of the Brain," this paper examines how subjective...

Investigation of the cerebral blood flow of an Omani man with supposed 'spirit possession' associated with an altered mental state : a case report.

Journal of Medical Case Reports December 10, 2009 Amr A Guenedi, Ala'Alddin Al Hussaini, Yousif A Obeid et al. 9 citations

The view that spirits may possess humans is found in 90% of the world population, including Arab/Islamic societies. Despite the association between possessive states and various neurological and psychiatric disorders, the available literature has yet to correlate possessive states with functional brain imaging modalities such as single-photon-emission computed tomography. This paper describes...

What are sleep-related experiences? Associations with transliminality, psychological distress, and life stress.

Consciousness and Cognition December 1, 2009 Nirit Soffer-Dudek, Golan Shahar

Sleep-related experiences [Watson, D. (2001). Dissociations of the night: Individual differences in sleep-related experiences and their relation to dissociation and schizotypy. Journal of Abnormal Psychology, 110, 526-535] refer to a host of nocturnal altered-consciousness phenomena, including narcoleptic tendencies, nightmares, problem-solving dreams, waking dreams, and lucid dreams. In an...

Altered affective response in marijuana smokers: an FMRI study.

Drug and Alcohol Dependence November 1, 2009 Staci A Gruber, Jadwiga Rogowska, Deborah A Yurgelun-Todd

More than 94 million Americans have tried marijuana, and it remains the most widely used illicit drug in the nation. Investigations of the cognitive effects of marijuana report alterations in brain function during tasks requiring executive control, including inhibition and decision-making. Endogenous cannabinoids regulate a variety of emotional responses, including anxiety, mood control, and...

The endocannabinoid system as a target for modelling psychosis.

Psychopharmacology November 1, 2009 Dagmar Koethe, Carolin Hoyer, F Markus Leweke

Model psychosis is characterised by experimentally induced symptoms of withdrawal from reality, frequently accompanied by perceptual disturbances, thought disorders, delusional ideas and sometimes by hallucinations. These "altered states of consciousness" provide a long-standing and valid approach to enhance our understanding of certain aspects of schizophrenia. Targeting the endocannabinoid...

Effects of a hypnotically altered state of consciousness on intensification of semantic processing.

International Journal of Clinical and Experimental Hypnosis October 2009 István Szendi, Zoltán Ambrus Kovács, György Szekeres et al.

In a study of the linguistic processes involved in hypnosis, 22 volunteer medical students performed semantic and phonologic fluency tasks and then associative priming tests with 2 delay-lengths in waking alert and hypnotic conditions as well. The participants performed better during semantic than phonological fluency tests in alert and also in hypnotic states, and this difference was...
