Possession and Jinn

Journal of the Royal Society of Medicine July 29, 2005 Najat R. Khalifa, Tim Hardie 79 citations

Religion remains a powerful influence on notions of health and disease.1 One Islamic concept that has entered into western mythology is that of the jinn or genies, as in the story of Aladdin. However, according to Islamic belief, jinn are real creatures that form a world other than that of mankind, capable of causing physical and mental harm to human beings. An example of such harm is...

Predicting the stream of consciousness from activity in human visual cortex.

Current Biology July 26, 2005 John-Dylan Haynes, Geraint Rees

Can the rapid stream of conscious experience be predicted from brain activity alone? Recently, spatial patterns of activity in visual cortex have been successfully used to predict feature-specific stimulus representations for both visible and invisible stimuli. However, because these studies examined only the prediction of static and unchanging perceptual states during extended periods of...

Role of α2A‐adrenoceptors in the effects of MDMA on body temperature in the mouse

British Journal of Pharmacology July 18, 2005 Sotiria Bexis, James R. Docherty 43 citations

3,4‐Methylenedioxymetamphetamine (MDMA) produces complex effects on body temperature, including hypo‐ and hyperthermic components that vary with ambient temperature and strain of rat. We have previously reported that MDMA is an α 2 ‐adrenoceptor agonist, and α 2 ‐adrenoceptor agonists such as clonidine produce hypothermia. The purpose of this study was to investigate the effects of MDMA on core...

Evidence for a common biological basis of the absorption trait, hallucinogen effects, and positive symptoms: Epistasis between 5-HT2a and COMT polymorphisms

American Journal of Medical Genetics. Part B, Neuropsychiatric Genetics June 17, 2005 Ulrich Ott, Martin Reuter, Juergen Hennig et al. 96 citations

Absorption represents a disposition to experience altered states of consciousness characterized by intensively focused attention. It is correlated with hypnotic susceptibility and includes phenomena ranging from vivid perceptions and imaginations to mystical experiences. Based on the assumption that drug-induced and naturally occurring mystical experiences share common neural mechanisms, we...

Quantum physics in neuroscience and psychology: a neurophysical model of mind-brain interaction.

Philosophical transactions of the Royal Society of London. Series B, Biological sciences June 1, 2005 Jeffrey M Schwartz, Henry P. Stapp, Mario Beauregard

Neuropsychological research on the neural basis of behaviour generally posits that brain mechanisms will ultimately suffice to explain all psychologically described phenomena. This assumption stems from the idea that the brain is made up entirely of material particles and fields, and that all causal mechanisms relevant to neuroscience can therefore be formulated solely in terms of properties of...

Meditation alters perceptual rivalry in Tibetan Buddhist monks

Current Biology June 1, 2005 Olivia Carter, David E. Presti, C. Callistemon et al. 262 citations

Neuroscientific studies of the mind are likely to benefit from the insights and skills of Tibetan Buddhist monks who have practiced the historic tradition of meditative training over many years — a point made recently at a forum between a selection of Buddhist leaders and distinguished scientists [1]. Perceptual rivalries, such as binocular rivalry [2] and motion induced blindness [3], are...

Deleuze and Horror Film

March 24, 2005 A. Powell

This book argues that dominant psychoanalytic approaches to horror films neglect the aesthetics of horror. Yet cinematic devices such as mise en scene, editing and sound, are central to the viewer's visceral fear and arousal. Using Deleuze's work on art and film, Anna Powell argues that film viewing is a form of 'altered consciousness' and the experience of viewing horror film an 'embodied...

Modulating the Rate and Rhythmicity of Perceptual Rivalry Alternations with the Mixed 5-HT2A and 5-HT1A Agonist Psilocybin

Neuropsychopharmacology January 26, 2005 Olivia Carter, John D. Pettigrew, Felix Hasler et al. 122 citations

Binocular rivalry occurs when different images are presented simultaneously to corresponding points within the left and right eyes. Under these conditions, the observer's perception will alternate between the two perceptual alternatives. Motivated by the reported link between the rate of perceptual alternations, symptoms of psychosis and an incidental observation that the rhythmicity of...

Functional neuroimaging in the vegetative state

Neurorehabilitation January 22, 2005 Steven Laureys

The interest of functional imaging in patients in a vegetative state is twofold. First, the vegetative state continues to represent a major clinical and ethical problem, in terms of diagnosis, prognosis, treatment, everyday management and end-of-life decisions. Second, it offers a lesional approach to the study of human consciousness and adds to the international research effort on identifying...

Anomalous Subjective Experience among First-Admitted Schizophrenia Spectrum Patients: Empirical Investigation

Psychopathology 2005 Josef Parnas, Peter Handest, Lennart Jansson et al.

Our research group has for several years conducted philosophically informed, phenomenological-empirical studies of morbid alterations of conscious experience (subjectivity) in schizophrenia (Sz) and its spectrum of disorders. Some of these experiential alterations constitute, in our view, the vulnerability markers to Sz – indicators that are intrinsic to this disorder and which were...
