On Being Available. Conversations with Silvia Călin

Martor. The Museum of the Romanian Peasant Anthropology Review November 14, 2025 Laura Jiga Iliescu

This interview focuses on the act of dancing as a corporeal experience that connects body and mind as part of an indestructible unit deployed in specific spatial and temporal arenas. In this respect, traditional folk dances and dancers share with modern performers and dance performances a corpus of sensorial and cognitive tools for bodily exploration. The dialogue is between Silvia Călin, a...

A Comparative Neurophenomenology of the Psychedelic State and Autism: Predictive Processing as a Unifying Lens

Psychoactives November 14, 2025 William Roseby, Catriona Osborn Moar

Serotonergic psychedelics, particularly psilocybin, lysergic acid diethylamide (LSD), and dimethyltryptamine (DMT), are increasingly recognised as powerful tools to advance the understanding of consciousness and its relation to brain activity. Psychedelic research has informed neuroscientific theories that attempt to map neural observations of network connectivity and signal diversity to...

The neuroscience of highly stable, positive, and refined states of consciousness during jhana-type advanced concentration absorption meditation (ACAM-J).

bioRxiv : the preprint server for biology November 13, 2025 Winson F.z. Yang, Ruby M. Potash, Grace Mackin et al. preprint

Humans can experience a rich array of conscious experience, including highly stable, positive, and refined states of non-ordinary perception that can be elicited through advanced meditation. Here, we present the first group-level, ultra-high-field (7T) fMRI study of jhana advanced concentration absorption meditation (ACAM-J). We combined local (regional homogeneity), mesoscale (connectivity...

Correction: Synergistic, multi-level understanding of psychedelics: three systematic reviews and meta-analyses of their pharmacology, neuroimaging and phenomenology.

Translational Psychiatry November 13, 2025 Kenneth Shinozuka, Katarina Jerotic, Pedro A. M. Mediano et al. correction

The meta-analysis of the 11-dimensional Altered States of Consciousness (11D-ASC) included three studies that contained duplicated data from other papers: Duerler et al. (2021), Lewis et al. (2017), and Preller et al. (2017). When these studies are removed from the analysis, the results are generally similar to the previously reported findings. Out of 33 comparisons (3 doses x 11 dimensions)...

Psychedelics and collective trauma: multisystemic resilience and recovery pathways among Nova festival survivors - a qualitative study.

European Journal of Psychotraumatology November 12, 2025 Guy Simon, Maya Gal-Birman, Nir Tadmor et al. 5 citations

Objective: On 7 October 2023, a mass-casualty attack at the Nova festival in Israel created an unprecedented convergence of collective trauma and altered states of consciousness. Many survivors were under the influence of psychedelics or other psychoactive substances at the time of the attack. This study explored how survivors made sense of and navigated recovery, with a focus on relational,...

Overcoming challenges in meditation assessment: Development and validation of the Meditation Pictographic Scale (MPS)

PsyArXiv November 11, 2025 Ylenia D'elia, Óscar Lecuona, Rocío Herrero et al. preprint

Measuring subjective experience during meditation remains methodologically challenging due to reliance on verbal self-reports for embodied phenomena. To address this, we developed the Meditation Pictographic Scale (MPS) using a first-person phenomenological approach. We developed and validated the MPS across four phases: (1) qualitative interviews to refine pictographic items; (2)...

Intact neurophysiological markers of death denial in long-term ayahuasca users

Psychopharmacology November 10, 2025 Yair Dor-Ziderman, Jonathan David, Aviva Berkovich-Ohana

These findings provide preliminary evidence that while ayahuasca may alter how humans interact with the theme of death on conceptual and affective levels of cognitive processing, on automatic, perceptual unconscious levels of self-specific processing, death-denial processes appear to remain intact.

Ketamine disrupts consciousness in healthy participants in relation with psychotic-like symptoms.

bioRxiv : the preprint server for biology November 8, 2025 Lucie Berkovitch, Alexandre Salvador, Thomas Andrillon et al. preprint

Ketamine is an NMDA-receptor antagonist, which alters the state of wakeful consciousness at high doses. At lower doses, it induces reversible psychotic-like symptoms and has been used as a pharmacological model of psychosis. In this study, we explore whether low doses of ketamine disrupt conscious access in relation with its psychotomimetic effects, and investigate the neural correlates of its...

The micro-phenomenology of Floatation-REST

BMC Complementary Medicine and Therapies November 6, 2025 Helena Hruby, Marc Wittmann, Stefan Schmidt et al.

This micro-phenomenological study examines altered states of consciousness (ASC) during Floatation-REST, a sensory isolation method where individuals lie in a tank filled with Epsom salt-saturated water in complete silence and darkness. Salubrious effects of Floatation-REST have been shown in persons suffering from mental health conditions; these positive outcomes might be related to the...

A Thematic Analysis of the Subjective Effects and Phenomenology of Ibogaine Administered in a Clinical Setting

Research Square November 5, 2025 Joseph T. la Torre, Step Cheung, Ariana Kam et al. preprint

Abstract Drawing on an unprecedentedly larger sample (N = 236) than previous studies, we investigated the subjective effects of ibogaine by asking a series of three original, open-ended questions to participants enrolled in an ibogaine-assisted treatment program at a specialized healthcare facility in México. The objective was to characterize the overall phenomenology of the subjective ibogaine...
