Visual perspective, distance, and felt presence of others in dreams.

Consciousness and Cognition August 1, 2023 Burak Erdeniz, Ege Tekgün, Bigna Lenggenhager et al. 2 citations

The peripersonal space, that is, the limited space surrounding the body, involves multisensory coding and representation of the self in space. Previous studies have shown that peripersonal space representation and the visual perspective on the environment can be dramatically altered when neurotypical individuals self-identify with a distant avatar (i.e., in virtual reality) or during clinical...

Anthropology of Consciousness July 31, 2023 Christopher Santiago

My art (Figures 1-7) revolves around the theory and practice of cultural resistance, which I call the ‘dreamweapon’ or the shamanic aspect of the fight for social justice. Through repetitive patterns, highly saturated colours, stark black and white alteration and abstracted anthropomorphisms, these paintings unleash an excess of spirits, a profusion of phantasmata, pineal eyes in ecstatic...

Fundamentals of Yoga Meditation: Physical and Mental Benefits

July 26, 2023 Wazir C Vasudeva

5-HT2AR and NMDAR psychedelics induce similar hyper-synchronous states in the rat cognitive-limbic cortex-basal ganglia system.

Communications Biology July 26, 2023 Ivani Brys, Sebastian A Barrientos, Jon Ezra Ward et al. 33 citations

The profound changes in perception and cognition induced by psychedelic drugs are thought to act on several levels, including increased glutamatergic activity, altered functional connectivity and an aberrant increase in high-frequency oscillations. To bridge these different levels of observation, we have here performed large-scale multi-structure recordings in freely behaving rats treated with...

Between the mind and the senses: Jean Mitry’s approach to cinematic consciousness

AN-ICON July 21, 2023 Federica Cavaletti

Representing altered states of consciousness, even through the most phantasmal of technical images, is an inherent contradiction; once we attribute a physical body, i.e. objectivity, to mental images, we deny what Husserl considers their very essence. Jean Mitry draws from this assumption when discussing filmic access to mental states from a phenomenological perspective. The following essay...

Measuring acute effects of subanesthetic ketamine on cerebrovascular hemodynamics in humans using TD-fNIRS.

Scientific Reports July 19, 2023 Adelaida Castillo, Julien Dubois, Ryan M. Field et al. 19 citations

Quantifying neural activity in natural conditions (i.e. conditions comparable to the standard clinical patient experience) during the administration of psychedelics may further our scientific understanding of the effects and mechanisms of action. This data may facilitate the discovery of novel biomarkers enabling more personalized treatments and improved patient outcomes. In this single-blind,...

Comparing Neural Correlates of Consciousness: From Psychedelics to Hypnosis and Meditation

Biological Psychiatry: Cognitive Neuroscience and Neuroimaging July 17, 2023 Flora Moujaes, Nathalie M. Rieser, Christophe Phillips et al. 19 citations

BACKGROUND: Pharmacological and nonpharmacological methods of inducing altered states of consciousness (ASCs) are becoming increasingly relevant in the treatment of psychiatric disorders. While comparisons between them are often drawn, to date no study has directly compared their neural correlates. METHODS: To address this knowledge gap, we directly compared 2 pharmacological methods...
