Quantitative Analysis of Electroencephalography in Hypnosis: A Neurophysiological Approach.

International Journal of Clinical and Experimental Hypnosis October 20, 2026 Golnaz Baghdadi, Ali Motie Nasrabadi

Hypnosis is a unique state of consciousness marked by heightened response to suggestions, focused attention, and altered cognitive control. This article explores the neural connections involved in hypnosis through electroencephalography (EEG) studies, examining brain changes during hypnosis and their relationship to hypnotic depth and susceptibility. Theta waves, linked to hypnotic depth, are...

From Verbal Attribution to Internal Measurement A Cross-System Framework for Comparing Human Brain and Artificial Intelligence Responses to External Stimuli

OSF Preprints October 19, 2026 Ricky Lee preprint

Abstract Public discussions about whether artificial intelligence possesses emotions, subjective experience, or even consciousness often rely on linguistic output, behavioral performance, and observers’ judgments. An AI system’s ability to describe its own state is not, by itself, sufficient to demonstrate subjective experience. At the same time, the fact that an AI system is non-biological...

Feeling safe: an empirical-ethical analysis of vulnerability in (es)ketamine treatment

BMC Medical Ethics October 18, 2026 Adrian Kind, Josephine Görke, Hannah Smirr et al.

Abstract Background Treatments with acute consciousness-altering effects, such as (es)ketamine, place patients in a state of heightened vulnerability with reduced capacity for self-advocacy and self-regulation. Since feeling safe is a precondition for consenting to begin, and remaining in, treatment, this raises distinct ethical demands on care. Which features of the setting enable patients to...

From Altered States to Fundamental Peace: Taxonomies of Consciousness, Psychedelics and Hypnosis Through the Lens of the Yoga Vāsiṣṭha

Journal of Happytalism and Fundamental Peace October 18, 2026 Luis Miguel Gallardo

Background Psychedelic medicine is approaching regulatory approval, and suggestion alone can now occasion mystical-type experiences in the laboratory. Yet the field still names altered states after their triggers, and nobody can yet show whether the state itself, rather than its context, is what heals. Objective This review reads the evidence presented at the 2026 Annual Conference of the...

The Sound of Hypnotherapy: Identification of Paralinguistic Speech Features Using Acoustic Analysis and Deep Learning.

Journal of voice : official journal of the Voice Foundation October 16, 2026 Albin Grataloup, Angélique Remacle

Hypnosis is an altered state of consciousness characterized by focused attention and heightened suggestibility, with therapeutic applications in a range of mental and somatic conditions. While prior research has emphasized the linguistic content of hypnotic suggestions (ie, what is said), the paralinguistic and acoustic characteristics of the hypnotist's speech (ie, how it is said) remain...

Center for Anticipation 2.0: Human, Artificial Intelligence, and Domain Expert in the Study of Possible Futures

Zenodo (CERN European Organization for Nuclear Research) October 13, 2026 Sergey Antonovich Kravchenko preprint

Center for Anticipation 2.0 is an independent research initiative founded by Sergey Antonovich Kravchenko, continuing the work of the original Center for Anticipation (2008–2018). The project investigates how possible futures are represented in human experience through dreams, intuition, premonitions, altered states of consciousness, and anticipatory processes. Particular attention is given to...

The Fundamental Observer Hypothesis (FOH): A Non-Dual Computational Framework Resolving the Hard Problem of Consciousness

Zenodo (CERN European Organization for Nuclear Research) October 13, 2026 Devraj Prime preprint

Current neuroscientific paradigms primarily rely on emergentism to explain subjective qualitative experience (qualia), positing that consciousness arises organically from complex neural architecture. Despite extensive mapping of neural correlates, the "Hard Problem of Consciousness" remains unresolved, failing to explain how physical matter generates subjective awareness. The Fundamental...

How Psychedelic VR Experience Alters Body Ownership: An Exploratory Study

Figshare October 13, 2026 Marika Iwashita preprint

Sense of ownership is defined as the feeling that a body part belongs to oneself. While altered states of consciousness have been extensively studied, their effects on bodily self-perception and susceptibility to perceptual illusions remain largely unexplored. This study investigated how psychedelic-like VR experience alters sense of ownership, using a tool “Oscilleditor” by Qualia Research...

Wave-function formalism for evolving neural dynamics: a mathematical framework informed by EEG

Frontiers in Computational Neuroscience October 12, 2026 Madelyn Klebba

The organization of distributed neural activity remains one of the central challenges in computational neuroscience. Contemporary frameworks, including Integrated Information Theory, Global Workspace Theory, entropy-based approaches, and electromagnetic field theories, have advanced our understanding of neural coordination but employ different mathematical descriptions of large-scale brain...

Editorial: Understanding conscious experiences during sleep

Frontiers in Sleep October 12, 2026 Adriana Michalak, Claudia Picard-Deland, Giulio Bernardi et al.

The sleeping brain hosts a spectrum of subjective experiences, ranging from fleeting hypnagogic images and simple thoughts to vivid, full-fledged dreams and lucid dreaming. The works published in this Research Topic present novel methodological and conceptual approaches to studying these experiences. Contributions span the challenges of studying dreaming in clinical populations (Fischmann et...
