The ontology and epistemology of symptoms: The case of auditory verbal hallucinations in schizophrenia

Oxford Medicine Online April 1, 2017 Josef Parnas, Annick Urfer-Parnas

We present a phenomenological account of auditory verbal hallucinations (AVH) in schizophrenia. We examine the mode of articulation of AVH, their spatial and temporal characteristics, and their relation to self-alienation, reflecting an emergence of otherness (alterity) in the midst of the patient’s self. This process of self-alienation is associated with the emergence of a different reality, a...

Stream of consciousness: Quantum and biochemical assumptions regarding psychopathology.

Medical Hypotheses April 1, 2017 Lucio Tonello, Massimo Cocchi, Fabio Gabrielli et al.

The accepted paradigms of mainstream neuropsychiatry appear to be incompletely adequate and in various cases offer equivocal analyses. However, a growing number of new approaches are being proposed that suggest the emergence of paradigm shifts in this area. In particular, quantum theories of mind, brain and consciousness seem to offer a profound change to the current approaches. Unfortunately...

Extreme rituals in a BDSM context: the physiological and psychological effects of the 'Dance of Souls'.

Culture, health & sexuality April 1, 2017 Kathryn R. Klement, Ellen M Lee, James K. Ambler et al. 25 citations

Participation in extreme rituals (e.g., fire-walking, body-piercing) has been documented throughout history. Motivations for such physically intense activities include religious devotion, sensation-seeking and social bonding. The present study aims to explore an extreme ritual within the context of bondage/discipline, dominance/submission and sadism/masochism (BDSM): the 'Dance of Souls', a...

Posterior cingulate cross-hemispheric functional connectivity predicts the level of consciousness in traumatic brain injury.

Scientific Reports March 24, 2017 Haosu Zhang, Rui Dai, Pengmin Qin et al.

Previous studies have demonstrated that altered states of consciousness are related to changes in resting state activity in the default-mode network (DMN). Anatomically, the DMN can be divided into anterior and posterior regions. The anterior DMN includes the perigenual anterior cingulate cortex and other medial prefrontal cortical regions, whereas the posterior DMN includes regions such as the...

Embodied Medicine: Mens Sana in Corpore Virtuale Sano

Frontiers in Human Neuroscience March 16, 2017 Giuseppe Riva, Silvia Serino, Daniele Di Lernia et al.

Progress in medical science and technology drastically improved physicians’ ability to interact with patient’s physical body. Nevertheless, medicine still addresses the human body from a Hippocratic point of view, considering the organism and its processes just as a matter of mechanics and fluids. However, the interaction between the cognitive neuroscience of bodily self-consciousness (BSC),...

Changes in the sense of agency during hypnosis: The Hungarian version of the Sense of Agency Rating Scale (SOARS-HU) and its relationship with phenomenological aspects of consciousness.

Consciousness and Cognition March 2017 András Költő, Vince Polito

Changes in the sense of agency are defining feature of hypnosis. The Sense of Agency Rating Scale (SOARS) is a 10-item questionnaire, administered after a hypnosis session to assess alteration in the sense of agency. In the present study, a Hungarian version of the measure (SOARS-HU) is presented. The SOARS-HU and the Phenomenology of Consciousness Inventory (PCI) were administered to 197...

Psychedelics and the science of self-experience

The British Journal of Psychiatry March 1, 2017 Matthew M. Nour, Robin Carhart-Harris 90 citations

Summary Altered self-experiences arise in certain psychiatric conditions, and may be induced by psychoactive drugs and spiritual/religious practices. Recently, a neuroscience of self-experience has begun to crystallise, drawing upon findings from functional neuroimaging and altered states of consciousness occasioned by psychedelic drugs. This advance may be of great importance for psychiatry.

Common and distinct brain regions processing multisensory bodily signals for peripersonal space and body ownership.

Neuroimage February 15, 2017 Petr Grivaz, Olaf Blanke, Andrea Serino

We take the feeling that our body belongs to us for granted. However, recent research has shown that it is possible to alter the subjective sensation of body ownership (BO) by manipulating multisensory bodily inputs. Several frontal and parietal regions are known to specifically process multisensory cues presented close to the body, i.e., within the peripersonal space (PPS). It has been...

SCIENCE, SPIRITUALITY, AND AYAHUASCA: THE PROBLEM OF CONSCIOUSNESS AND SPIRITUAL ONTOLOGIES IN THE ACADEMY

Zygon: Journal of Religion and Science February 12, 2017 Ismael Apud 9 citations

Ayahuasca is a psychoactive brew from Amazonas, popularized in the last decades in part through transnational religious networks, but also due to interest in exploring spirituality through altered states of consciousness among academic schools and scientific researchers. In this article, the author analyzes the relation between science and religion proposing that the “demarcation problem”...
