‘Psychologisation’ of Madness: The Problem of Possession

April 8, 2012 Mira Marcinów

In this chapter I aim to present other than only a historical distinction criteria of the psychological characteristics of madness. Michel Foucault was the first person who tried to define this problem in his book Mental Illness and Psychology (1954/2000). Between the two well known processes: ‘medicalization’ and ‘romanization’ of madness we have got one of the most influential approaches...

Acute intoxication caused by a synthetic cannabinoid in two adolescents.

The journal of pediatric pharmacology and therapeutics : JPPT : the official journal of PPAG April 2012 Travis S Heath, Zachary Burroughs, A Jill Thompson et al.

Illicit drug use continues to be a common problem among pediatric patients. Daily marijuana use among high school seniors is currently at a 30-year high. Marijuana use in adults has rarely been associated with cardiovascular adverse effects, including hypertension, tachycardia, arrhythmia, and myocardial infarction. Recently, abuse of synthetic cannabinoids, such as the incense "K2" or "Spice,"...

Effects of 3,4‐methylenedioxymethamphetamine (MDMA) and its metabolites on cardiovascular function in rats

The FASEB Journal April 1, 2012 Charles W. Schindler, Michael H Baumann, Eric B. Thorndike et al.

The abuse of MDMA (Ecstasy) peaked in the early 2000s, yet reports of MDMA use from emergency room admission data continue to increase. The potential for cardiovascular effects of MDMA to contribute to its acute toxicity has long been recognized. However, the role of MDMA metabolites in mediating the drug's cardiovascular actions has not been studied. Here we employed radiotelemetry to evaluate...

Disorganized Attachment Promotes Mystical Experiences via a Propensity for Alterations in Consciousness (Absorption)

March 6, 2012 Pehr Granqvist, Berit Hagekull, T. Ivarsson

Abstract In this article, the authors argue that mystical experiences are linked to disorganized attachment via a proposed mediator—the propensity to enter altered states of consciousness (absorption). Using a sample of predominantly religious/spiritual participants (N = 62), they report that disorganized attachment, as identified with the Adult Attachment Interview, predicted lifetime...

Mismatch negativity encoding of prediction errors predicts S-ketamine-induced cognitive impairments.

Neuropsychopharmacology March 2012 André Schmidt, Rosilla Bachmann, Michael Kometer et al.

Psychotomimetics like the N-methyl-D-aspartate receptor (NMDAR) antagonist ketamine and the 5-hydroxytryptamine2A receptor (5-HT(2A)R) agonist psilocybin induce psychotic symptoms in healthy volunteers that resemble those of schizophrenia. Recent theories of psychosis posit that aberrant encoding of prediction errors (PE) may underlie the expression of psychotic symptoms. This study used a...

EEG oscillatory states as neuro-phenomenology of consciousness as revealed from patients in vegetative and minimally conscious states.

Consciousness and Cognition March 1, 2012 Alexander A Fingelkurts, Andrew A Fingelkurts, Sergio Bagnato et al. 91 citations

The value of resting electroencephalogram (EEG) in revealing neural constitutes of consciousness (NCC) was examined. We quantified the dynamic repertoire, duration and oscillatory type of EEG microstates in eyes-closed rest in relation to the degree of expression of clinical self-consciousness. For NCC a model was suggested that contrasted normal, severely disturbed state of consciousness and...

Ayahuasca as Antidepressant? Psychedelics and Styles of Reasoning in Psychiatry

Anthropology of Consciousness March 1, 2012 B. Anderson 29 citations

Abstract There is a growing interest among scientists and the lay public alike in using the S outh A merican psychedelic brew, ayahuasca, to treat psychiatric disorders like depression and anxiety. Such a practice is controversial due to a style of reasoning within conventional psychiatry that sees psychedelic‐induced modified states of consciousness as pathological. This article analyzes the...

Cortical mechanisms of loss of consciousness: insight from TMS/EEG studies.

Archives italiennes de biologie 2012 Marcello Massimini, Fabio Ferrarelli, Simone Sarasso et al.

In a recent series of experiments we recorded the electroencephalogram (EEG) response to a direct cortical stimulation in humans during wakefulness, NREM sleep, REM sleep and anesthesia by means of a combination of transcranial magnetic stimulation (TMS) and high-density EEG (hd-EEG). TMS/hd-EEG measurements showed that, while during wakefulness and REM sleep the brain is able to sustain...

A case study of primary process language and body boundary imagery in discourses of religious-mystical and psychotic experiences

2012 Laura A. Cariola

Religious-mystical and psychotic altered states of consciousness (ASC) are assumed to share common phenomenological and psychobiological features, including regressive cognition and changes in body boundary awareness. This study aimed to assess the frequency and strength of associations between primordial thought language and body boundary imagery in the discourses of mystical and...

God Don't Make No Junk: A Look at Making Art and the Theology of Desire

ERA: Education and Research Archive 2012 Patricia Catherine Worthingham

This integrative study provides an historical review of humankind’s relationship with desire as regarded by philosophers and theologians of western civilization. It examines desire as reflected in the characteristics of our culture and the societies we have built since early history; then highlights which desires, according to Dr. Steven Reiss’ research into what motivates and makes life...
