Subjective Experience of “Stream of Consciousness Impairment” in Three Patients with Severe Amnesia

June 24, 2026 Anaïs Servais, Fleur Gérard, Hélène Mirabel et al. preprint

Patients with severe anterograde amnesia have been described as "stuck in time"; their mental time travel abilities are altered, and they seem to live in the present. Here, we examine an unusual phenomenon in which severely amnesic patients recurrently report the belief that they have just awakened from an unconscious state. A famous case illustrating this phenomenon was that of Clive Wearing...

Dissociative Identities as Archetypal Scaffolds: Integrating Neuroscience, DSM-5-TR, and Analytical Psychology

Emirati Journal of Applied Psychology June 24, 2026 Chacko George

Contemporary psychiatric models conceptualize dissociative disorders primarily as stress-induced disruptions in the integration of consciousness, memory, and identity. While DSM-5-TR frameworks and classical psychopathology effectively describe the neurobiological and defensive mechanisms underlying dissociation, they provide limited explanation for the coherent, symbolically meaningful, and...

Mechanistic insights toward dissociating therapeutic from psychedelic effects: bridging the gap between psychedelic research and mental health care

Translational Psychiatry June 24, 2026 Mauro Pettorruso, Giacomo D’andrea, Antonio Inserra et al.

Clinical trials investigating psychedelic compounds for depression and anxiety-related disorders are yielding promising preliminary results. Psychedelics produce profound alterations in brain function—such as suppression of the default mode network and thalamocortical dysregulation—leading to intense subjective experiences including ego dissolution and mystical-type states. While often...

Out-Of-Body Experiences During Sleep Show Altered-Self Phenomenology Without A Distinct Clinical Profile

PsyArXiv June 21, 2026 Nerea L Herrero, Yohann Corfdir, Cecilia Forcato preprint

Out-of-body experiences (OBEs) during sleep involve a transient disruption of bodily self-consciousness, in which the self or center of awareness is experienced as displaced from the physical body. Although OBEs have been reported in neurological, psychiatric, and dissociative contexts, they also occur in non-clinical populations, raising the question of whether their altered-self phenomenology...

Defining Advanced Meditation A Conceptual Foundation for a Comprehensive Contemplative Science beyond Mindfulness Meditation, Basic Meditation, and Other Non-Meditative Consciousness-Altering Practices

PsyArXiv June 20, 2026 Terje Sparby, Brian Toomey, Malcolm Wright et al. preprint

This article proposes a definition of advanced meditation which in concise form is the states, stages, and endpoints that arise with the maturation and mastery of awareness skills. Advanced meditation involves experiential and structural mental changes, sometimes radical, to volition, affect, cognition, and self-related processing in the direction of effortlessness, intentional control,...

First-Person Psychopharmacology (1PPP): A New Way Forward for Clinical Trials

Journal of Humanistic Psychology June 19, 2026 Radosław Stupak, Pesach Lichtenberg

Despite decades of research, psychiatric pharmacotherapy remains limited in its clinical effectiveness and understanding of therapeutic mechanisms. Dominant approaches, rooted in symptom-scale-driven randomized controlled trials (RCTs) and biological reductionism, often fail to capture the complex, subjective, and context-dependent nature of psychotropic drug effects. In this article, we...

Biotransenergetics and Essential Transe. The Self, the Field, and Transe as Foundations of an Integral Transpersonal Psychotherapy

Dialogo June 18, 2026 Pier Luigi Lattuada

This article presents Biotransenergetics (BTE) as an integral transpersonal psychotherapy grounded in an embodied, participatory, and non-dual epistemology of consciousness. Developed by Pier Luigi Lattuada, BTE proposes a radical redefinition of the therapeutic process through the centrality of the Self, the concept of Transe, and the experiential realization of Essential Transe. The article...

The Neuroscience and Psychology of the Alien Abduction Phenomenon: An Extended Review

June 17, 2026 Pascal Michael preprint

The phenomenon of alien abduction has been widely reported yet remains scientifically contentious. This review synthesizes neuroscientific and psychological findings to elucidate its potential mechanisms. Neural correlates include sleep paralysis, REM intrusion, temporoparietal junction activity, caudate-putamen connectivity, serotonergic modulation (e.g., 5-HT2A receptor) & thanatosis...

Informe de Observación Neurofenomenológica sobre Estados Alterados de Conciencia Inducidos por Psilocibina

Zenodo (CERN European Organization for Nuclear Research) June 17, 2026 Fernando Valinsky preprint

This report presents a detailed phenomenological analysis of a self-observed psilocybin experience conducted under controlled conditions and documented through contemporaneous notes and post-session reconstruction. The study focuses on the structure of subjective experience rather than on pharmacological outcomes alone. Particular attention is given to alterations in bodily awareness, spatial...

Acute Effects of Esketamine on the EEG Power Spectrum and Signal Complexity in Prolonged Disorders of Consciousness: A Prospective Exploratory Cohort Study.

Journal of neurosurgical anesthesiology June 15, 2026 Yi Liang, Wanning Yang, Xinxin Wang et al.

Effective treatments for prolonged disorders of consciousness (pDoC) remain limited. Grounded in the entropic brain hypothesis-that psychedelic agents facilitate consciousness recovery by increasing brain complexity-this study investigated esketamine, a nonclassical psychedelic drug, and its effects on electroencephalographic (EEG) neurophysiological metrics in pDoC patients. In this...
