Abstract It has been proposed that both conscious and unconscious perception are associated with a feedforward sweep of oscillatory activity in the gamma band (>40 Hz), while conscious perception also requires recurrent feedback via beta band ($\sim$20 Hz) oscillations. To investigate the causal relationship between these oscillations and (un)conscious visual perception, we assessed the effect...

End-of-life dreams and visions (ELDVs) and delirium frequently occur near death but differ in core features. Clinical differentiation becomes challenging when they co-occur. This case report illustrates the interplay between ELDVs and delirium, examines the limits of current diagnostic criteria in mixed cases, and outlines a nuanced approach to distinction. We report the case of an elderly...
This study piloted and validated the Russian-language version of R. W. Hood’s Mysticism Scale in an adult sample. Two comparable groups participated (N = 200; age 19–61): 100 with self-reported mystical/transcendent experiences and 100 without such experiences. The adaptation used forward–back translation with expert review. Psychometrics included exploratory factor analysis (KMO = 0.86;...
Ketamine is a unique anesthetic agent that induces dissociative anesthesia, characterized by perceptual detachment, analgesia, and altered states of consciousness. Beyond its widespread use in anesthesia, subhypnotic ketamine dosing has emerged as a rapid-acting antidepressant and a valuable model for probing the neural mechanisms underlying consciousness and neuropsychiatric disorders. At the...
The Altered States of Consciousness Scale (3/5D-ASC or 11-ASC) is widely used to assess non-ordinary states of consciousness, particularly for psychedelic research. However, its original dimensional model (3D-ASC within 5D-ASC) and later 11-subscale structure (11-ASC) have a hierarchically incompatible higher/lower-order structure. Although the 11-ASC offers superior model fit, the 3D-ASC...
This article is devoted to the epistemology of Abu Ali ibn Sina in the context of quantum consciousness theory. It examines the psychological and cognitive characteristics and abilities of Shaykhurrais through the prism of quantum consciousness. Quantum biology is a new scientific field that studies the mechanism of activity and the emergence of consciousness. Classical approaches to its study...
Introduction. In Buddhism, human birth is considered a rare opportunity and the best condition — to put an end to further births and attain the utmost spiritual goals. In comparison to other realms of existence in saṃsāra (animals, pretas, etc.), the human realm is referred to as ‘the fortunate one’ and birth in a human body is called ‘the precious (Tib. rinchen) birth’. Goals. The work seeks...
Treatment-resistant depression (TRD) remains a significant public-health challenge, with many patients failing to respond to conventional therapies. Ketamine has emerged as a rapid-acting intervention, but quantitative outcomes alone do not capture patients' lived experiences, which shape engagement, acceptability, and adherence. We conducted a narrative review of qualitative and mixed-methods...
The specificity of Indian epistemic culture is the inclusion of mystical intuition among cognitive abilities, and the absence of the concept of reason as the highest cognitive ability. In Indian traditional religio-philosophical texts intuition, often referred to as mystical experience, was used by default. In the philosophical works of Aurobindo Ghosh (1872–1950), its epistemological status is...

The study examines how Indian Knowledge Systems (IKS) and modern psychology can be placed in a productive dialogue about cognition, emotion, meaning, and human development. It treats this dialogue as more than a comparison of concepts by highlighting differences in starting assumptions, methods of verification, and aims of psychological knowledge. The aims to clarify where IKS and contemporary...
