Characterisation of a proposed internet synthesis of N,N-dimethyltryptamine using liquid chromatography/electrospray ionisation tandem mass spectrometry.
Journal of Chromatography A August 14, 2009 Cláudia P.B. Martins, Sally Freeman, John F. Alder et al. 11 citations
The psychoactive properties of N,N-dimethyltryptamine (DMT) are known to induce altered states of consciousness in humans. These properties attract great interest from clinical, neuroscientific, clandestine and forensic communities. The Breath of Hope Synthesis was reported on an internet website as a convenient two-step methodology for the preparation of DMT. The analytical characterisation of...
Keeping in touch with one's self: multisensory mechanisms of self-consciousness.
PLoS One August 5, 2009 Jane E. Aspell, Bigna Lenggenhager, Olaf Blanke
Background: The spatial unity between self and body can be disrupted by employing conflicting visual-somatosensory bodily input, thereby bringing neurological observations on bodily self-consciousness under scientific scrutiny. Here we designed a novel paradigm linking the study of bodily self-consciousness to the spatial representation of visuo-tactile stimuli by measuring crossmodal...

Delusions, illusions and hallucinations in epilepsy: 2. Complex phenomena and psychosis.
Epilepsy research August 2009 Brent Elliott, Eileen Joyce, Simon Shorvon
In this second paper the clinical features and electrophysiological underpinnings of more complex psychotic states associated with epilepsy are reviewed. (a) Complex partial status epilepticus, in particular of temporal lobe origin, may result in mental states remarkably similar to those seen in the primary psychoses. This non-convulsive state is associated with prolonged epileptic discharges...
The Cross‐Cultural Evidence on “Extreme Behaviors”
Annals of the New York Academy of Sciences August 1, 2009 Jean E. Jackson 7 citations
Many kinds of body/mind practices are capable of producing remarkable behaviors and altered body states. A typology of such behaviors and states, defined as observable and intentional "extreme" alterations to the body, is presented. Epistemological and methodological issues are discussed: limitations of observational data, and role of meaning, intentionality, and consciousness. Rapprochement...
Neural correlates of stimulus reportability.
Journal of Cognitive Neuroscience August 1, 2009 Oliver J Hulme, Karl Friston, Semir Zeki
Most experiments on the "neural correlates of consciousness" employ stimulus reportability as an operational definition of what is consciously perceived. The interpretation of such experiments therefore depends critically on understanding the neural basis of stimulus reportability. Using a high volume of fMRI data, we investigated the neural correlates of stimulus reportability using a partial...

Penrose-Hameroff orchestrated objective-reduction proposal for human consciousness is not biologically feasible.
Physical review. E, Statistical, nonlinear, and soft matter physics August 1, 2009 Laura K McKemmish, Jeffrey R Reimers, Ross H McKenzie et al.
Penrose and Hameroff have argued that the conventional models of a brain function based on neural networks alone cannot account for human consciousness, claiming that quantum-computation elements are also required. Specifically, in their Orchestrated Objective Reduction (Orch OR) model [R. Penrose and S. R. Hameroff, J. Conscious. Stud. 2, 99 (1995)], it is postulated that microtubules act as...
Classical mindfulness: an introduction to its theory and practice for clinical application.
Annals of the New York Academy of Sciences August 1, 2009 Lobsang Rapgay, Alexander Bystrisky 168 citations
Among the modern versions of mindfulness, mindfulness based stress reduction (MBSR) has played the key role in introducing mindfulness practice to the field of psychology and medicine. In fact, the efforts to integrate mindfulness into psychology have resulted in further adaptation of MBSR into more secular and psychological forms as well as the creation of a number of mindfulness measures such...
Pattern Recognition Theory of Mind
arXiv Preprint Archive July 26, 2009 Gilberto de Paiva preprint
I propose that pattern recognition, memorization and processing are key concepts that can be a principle set for the theoretical modeling of the mind function. Most of the questions about the mind functioning can be answered by a descriptive modeling and definitions from these principles. An understandable consciousness definition can be drawn based on the assumption that a pattern recognition...
Cognition and Perception
July 17, 2009 Athanassios Raftopoulos
An argument that there are perceptual mechanisms that retrieve information in cognitively and conceptually unmediated ways and that this sheds light on various philosophical issues. In Cognition and Perception, Athanassios Raftopoulos discusses the cognitive penetrability of perception and claims that there is a part of visual processes (which he calls “perception”) that results in...
