[Stigmatisation and absence of nutrition in the case of Therese Neumann (1898-1962)].

Der Nervenarzt July 2008 O Seidl

Therese Neumann, from Konnersreuth in Bavaria, developed stigmata at the age of 29 and allegedly lived without any food for 36 years. After a fire accident in 1918, she suffered from paralysis, deafness, and blindness. Later she developed stigmata on her extremities and left side of the thorax, bleeding lesions in the skin, bleeding in the eye region, and altered states of consciousness in the...

Body ownership and embodiment: vestibular and multisensory mechanisms.

Neurophysiologie Clinique June 1, 2008 C Lopez, P Halje, Olaf Blanke

Body ownership and embodiment are two fundamental mechanisms of self-consciousness. The present article reviews neurological data about paroxysmal illusions during which body ownership and embodiment are affected differentially: autoscopic phenomena (out-of-body experience, heautoscopy, autoscopic hallucination, feeling-of-a-presence) and the room tilt illusion. We suggest that autoscopic...

Ego Boundaries, Shamanic‐Like Techniques, and Subjective Experience: An Experimental Study

Anthropology of Consciousness May 1, 2008 Adam J. Rock, Jessica Wilson, Luke Johnston et al. 18 citations

ABSTRACT The subjective effects and therapeutic potential of the shamanic practice of journeying is well known. However, previous research has neglected to provide a comprehensive assessment of the subjective effects of shamanic‐like journeying techniques on non‐shamans. Shamanic‐like techniques are those that demonstrate some similarity to shamanic practices and yet deviate from what may...

Pain, dissociation and subliminal self-representations.

Consciousness and Cognition March 2008 Petr Bob

According to recent evidence, neurophysiological processes coupled to pain are closely related to the mechanisms of consciousness. This evidence is in accordance with findings that changes in states of consciousness during hypnosis or traumatic dissociation strongly affect conscious perception and experience of pain, and markedly influence brain functions. Past research indicates that painful...

Lost—Found

Spiritus March 1, 2008 Douglas Burton‐Christie

Lost—Found Douglas Burton-Christie St. Augustine famously described the soul's ultimate meeting with God as a homecoming, a recognition of something known and familiar that has been lost. His uncanny sense of knowing what he was looking for even in the midst of the most intense experience of dislocation is part of what gives the Confessions such evocative power. It captures the strange but...

Effects of varied doses of psilocybin on time interval reproduction in human subjects

Neuroscience Letters February 13, 2008 Jiřı́ Wackermann, Marc Wittmann, Felix Hasler et al. 95 citations

Action of a hallucinogenic substance, psilocybin, on internal time representation was investigated in two double-blind, placebo-controlled studies: Experiment 1 with 12 subjects and graded doses, and Experiment 2 with 9 subjects and a very low dose. The task consisted in repeated reproductions of time intervals in the range from 1.5 to 5s. The effects were assessed by parameter kappa of the...

Highly schizotypal students have a weaker sense of self-agency.

Psychiatry and Clinical Neurosciences February 1, 2008 Tomohisa Asai, Yoshihiko Tanno

Schizotypy can be seen as an indicator of a predisposition to schizophrenia. It is possible that schizotypal people have an abnormal self-consciousness, especially with regard to the sense of self-agency. Students were rated using the Schizotypy Traits Questionnaire (STA). They were asked to press a button, which generated a tone after some delay. They were then required to judge whether they...

Use, function, and subjective experiences of gamma-hydroxybutyrate (GHB).

Drug and Alcohol Dependence January 1, 2008 Harry Sumnall, Kerry Woolfall, Sara Edwards et al.

Self-reported use of gamma-hydroxybutyrate (GHB) among clubbers has increased over the last decade, and is often reported in the scientific literature in association with negative events such as amnesia, overdose, and use in drug facilitated sexual assault. However, there has been relatively little work investigating the phenomenology of GHB intoxication, and the reasons underlying use. In this...

Alien abduction: a medical hypothesis.

The journal of the American Academy of Psychoanalysis and Dynamic Psychiatry 2008 David V Forrest

In response to a new psychological study of persons who believe they have been abducted by space aliens that found that sleep paralysis, a history of being hypnotized, and preoccupation with the paranormal and extraterrestrial were predisposing experiences, I noted that many of the frequently reported particulars of the abduction experience bear more than a passing resemblance to...

Ganzfeld-induced hallucinatory experience, its phenomenology and cerebral electrophysiology.

Cortex 2008 Jirí Wackermann, Peter Pütz, Carsten Allefeld

Ganzfeld, i.e., exposure to an unstructured, uniform stimulation field, elicits in most observers pseudo-hallucinatory percepts, and may even induce global functional state changes ('altered states of consciousness'). The present paper gives a comprehensive overview of the phenomenology of subjective experience in the ganzfeld and its electrophysiological correlates. Laboratory techniques for...
