Impact of an auditory hallucinations simulation on trainee and newly qualified clinical psychologists: A mixed-methods cross-sectional study.

Clinical Psychology & Psychotherapy May 2019 Simon Riches, Fareeha Khan, Shifaa Kwieder et al.

Simulation training is an effective teaching tool enabling learners to gain a subjective understanding of a range of skills. Our aim in this study was to pilot and evaluate a newly designed simulation of auditory hallucinations as a future training tool for clinicians. This was a mixed-methods study in two parts. In Phase 1, trainee and qualified clinical psychologists (N = 25) attended the...

The impact of musical structure on enjoyment and absorptive listening states in trance music

Music and Consciousness 2 April 11, 2019 Kat Agres, Louis Bigo, Dorien Herremans

Abstract: The act of listening to music to reach altered states of consciousness is common across many different cultures around the world, ranging from tribal settings in Central Java, Indonesia, to EDM (electronic dance music) dance clubs in the Western world. Despite the widespread listenership to trance music, we lack a comprehensive, scientific account of how features of the musical...

Structural isomorphism of noema and image-sprout

Вестник Православного Свято-Тихоновского гуманитарного университета: Серия I. Богословие, философия April 10, 2019 Nikolay Muskhelishvili, Andrey Antonenko

This paper examines the relationship between the E. Husserl’s theory of noema and N. L. Muskhelishivili’s and Yu. A. Schreider’s concept of the organising image (image-sprout) which was proposed in the paper “Meaning of Text as an Inner Image”. The purpose of this study is to demonstrate isomorphism of these two concepts. It can serve as a methodological and ideological basis for combining...

Cortical dynamics during psychedelic and anesthetized states induced by ketamine

Neuroimage April 5, 2019 Duan Li, George A. Mashour 103 citations

Ketamine is a unique drug that has psychedelic and anesthetic properties in a dose-dependent manner. Recent studies have shown that ketamine anesthesia appears to maintain the spatiotemporal complexity of cortical activation evoked by transcranial magnetic stimulation, while a psychedelic dose of ketamine is associated with increased spontaneous magnetoencephalographic signal diversity....

Receptor-Enriched Analysis of functional connectivity by targets (REACT): A novel, multimodal analytical approach informed by PET to study the pharmacodynamic response of the brain under MDMA

Neuroimage April 4, 2019 Ottavia Dipasquale, Pierluigi Selvaggi, Mattia Veronese et al. 79 citations

One of the main limitations of pharmacological fMRI is its inability to provide a molecular insight into the main effect of compounds, leaving an open question about the relationship between drug effects and haemodynamic response. The aim of this study is to investigate the acute effects of 3,4-methylenedioxymethamphetamine (MDMA) on functional connectivity (FC) using a novel multimodal method...

Inducing synesthesia in non-synesthetes: Short-term visual deprivation facilitates auditory-evoked visual percepts.

Consciousness and Cognition April 1, 2019 Anupama Nair, David Brang

Sounds can modulate activity in visual cortex, facilitating the detection of visual targets. However, these sound-driven modulations are not thought to evoke conscious visual percepts in the general population. In individuals with synesthesia, however, multisensory interactions do lead to qualitatively different experiences such as sounds evoking flashes of light. Why, if multisensory...

The physical nature of subjective experience and its interaction with the brain.

Medical Hypotheses April 1, 2019 Fredric Schiffer

Penrose and Hameroff assert that brain computations, including quantum computations, involving hydrophobic areas of microtubules whose electron clouds go into orchestrated superpositions and reductions that lead to proto-conscious elements, or "bings" that become orchestrated into conscious experiences. Their assertion, however, like the findings of the neural correlates of consciousness, does...

The oldest archeological data evidencing the relationship of Homo sapiens with psychoactive plants: A worldwide overview

Journal of Psychedelic Studies March 29, 2019 Giorgio Samorini

Modern sophisticated archeometric instruments are increasingly capable of detecting the presence of psychoactive plant sources in archeological contexts, testifying the antiquity of humanity’s search for altered states of consciousness. The purpose of this article is to provide a general picture of these findings, covering the main psychoactive plant sources of the world, and identifying the...

Connectivity differences between consciousness and unconsciousness in non-rapid eye movement sleep: a TMS–EEG study

Scientific Reports March 26, 2019 Minji Lee, Benjamin Baird, Olivia Gosseries et al. 98 citations

The neuronal connectivity patterns that differentiate consciousness from unconsciousness remain unclear. Previous studies have demonstrated that effective connectivity, as assessed by transcranial magnetic stimulation combined with electroencephalography (TMS-EEG), breaks down during the loss of consciousness. This study investigated changes in EEG connectivity associated with consciousness...
