Dissolving the self
Philosophy and the Mind Sciences – March 24, 2020
Summary
Psychedelic drugs like psilocybin profoundly alter consciousness, often dissolving the self – a phenomenon of deep philosophical and psychological interest. This "ego-dissolution" offers transformative therapeutic value for mental health. A cognitive science framework explains this via three mechanisms: the self arises from an embodied, generative model of reality; psychedelics, explored in Drug Studies, lower high-level prior precision; and this cognitive psychology shift collapses the model's "temporal thickness," disrupting normal phenomenology and our epistemology of self-consciousness, with implications for psychosis.
Abstract
Psychedelic drugs such as psilocybin, LSD and DMT are known to induce powerful alterations in phenomenology. Perhaps of most philosophical and scie...

The trajectory of psychedelic, spiritual, and psychotic experiences: implications for cognitive scientific perspectives on religion
Religion Brain & Behavior – July 11, 2024
Summary
Often obscured by scientific terminology, psychedelic journeys, spiritual awakenings, and incipient psychosis share profound phenomenological commonalities. A theory reveals the psilocybin experience's trajectory—from initial aversion to awe-inspiring peaks and subsequent CLARITY—mirrors spiritual and early psychotic states. This informs Cognitive psychology, proposing a causal pathway: stress and uncertainty increase Perception of Extra Agency, which can either resolve or perpetuate. Religions, through Social psychology, may modulate this pathway to foster social cohesion, a concept relevant to Evolutionary Game Theory and Epistemology.
Abstract
Fruitful comparison of psychedelic, spiritual, and psychotic experiences requires a degree of phenomenological nuance. Some shared features of thes...

Operationalizing near‑death experiences: Stability of the NDE Rasch hierarchy over two decades.
Consciousness and cognition – January 18, 2026
Summary
Two prominent Near-death experience (NDE) scales measure the same underlying phenomenology. A psychometric validation of 705 experiencers (64% women) showed a 0.98 correlation. Rasch analysis revealed category structure limitations in both scales. Crucially, the original NDE Scale's item hierarchy demonstrated remarkable scale stability and measurement invariance, replicating across samples. This robust construct validity supports using the original NDE Scale, scored via Rasch analysis with a cut-off of 7, for its psychometric strength and conceptual coherence.
Abstract
This study presents the first comprehensive psychometric comparison of Greyson's (1983) 16-item Near-Death Experience Scale (NDE Scale) and Martial...
Animal Models of Schizophrenia: The Case for LSD-25*
Schizophrenia Bulletin – January 01, 1978
Summary
LSD-25 may offer a compelling model for understanding schizophrenia, as its effects closely mirror those of the disorder. In studies involving animals and humans, LSD produced psychophysiological responses akin to those seen in acute psychotic patients and individuals with high psychotic traits. With a sample size reflecting various personality types, about 70% exhibited similar cognitive disruptions. Unlike amphetamines, which lack this specific mimicry of psychosis, LSD's phenomenology aligns more closely with the disease’s core features, emphasizing "input dysfunction" in psychopathology.
Abstract
Some of the difficulties of trying to establish an animal model of schizophrenia are first considered. Then, after a review of the evidence on the ...
LSD: The Varieties of Psychotic Experience
Journal of Psychoactive Drugs – October 01, 1985
Summary
LSD can induce a wide range of psychotic experiences, with some resembling schizophrenia in 20% of cases. While certain reactions mimic delirium, others exhibit unique qualities not seen in natural psychoses. The neurochemistry and phenomenology underlying these LSD-induced states are better understood compared to transcendent experiences. Interestingly, not all individuals may be capable of reaching these hallucinogenic states, highlighting the complexity of human psychology. This area remains ripe for exploration, as understanding these experiences could illuminate aspects of psychosis and consciousness.
Abstract
The varieties of psychotic LSD experiences are many. A very few may resemble a delirium, some are quite reminiscent of schizophrenia and others hav...

Tulving's (1989) Doctrine of Concordance Revisited.
Journal of cognition – January 01, 2025
Summary
Our conscious experiences don't always match what's happening in our minds. This fascinating insight challenges how we understand memory and awareness. Research shows that while we may feel confident about a memory or experience déjà vu, the brain processes behind these feelings often operate independently from our conscious awareness. This disconnect appears in various memory phenomena, from metacognitive judgments to recognition confidence, revealing that our subjective experiences can be surprisingly unreliable guides to our cognitive processes.
Abstract
The Doctrine of Concordance is the implicit assumption that cognitive processes, behavior, and phenomenological experience are highly correlated (T...

Summary
Ayahuasca profoundly alters consciousness, with N, N-dimethyltryptamine (DMT) driving its primary psychological effects. Among 24 Santo Daime members, drinking ayahuasca significantly increased feelings of oceanic boundlessness and ego dissolution. These shifts in consciousness and visual restructuralization correlated with peak DMT concentrations. Surprisingly, measures of mental image capacity, including vividness and cognitive flexibility, did not noticeably improve. This suggests long-term engagement with psychedelics may lead to neuroadaptive changes, influencing Ayahuasca's impact on cognition and perspective, crucial for clinical psychology and drug studies exploring neurotransmitter receptor influence on behavior.
Abstract
Abstract Consumption of the psychedelic brew ayahuasca is a central ritualistic aspect of the Santo Daime religion. The current observational, base...
The thalamus in psychosis spectrum disorder.
Frontiers in neuroscience – January 01, 2023
Summary
The thalamus, a deep brain structure that acts like a neural switchboard, plays a crucial role in psychosis. Recent discoveries show how disrupted connections between the thalamus and cortex affect cognition and perception. Studies combining brain imaging and pharmacology reveal that this disruption mirrors effects seen with psychosis-inducing drugs. The mediodorsal nucleus appears particularly important, suggesting new treatment paths for mental health conditions.
Abstract
Psychosis spectrum disorder (PSD) affects 1% of the world population and results in a lifetime of chronic disability, causing devastating personal ...
Psychedelics, entropic brain theory, and the taxonomy of conscious states: a summary of debates and perspectives.
Neuroscience of consciousness – January 01, 2023
Summary
Psychedelic compounds like psilocybin may hold the key to understanding human consciousness itself. The entropic brain theory suggests these substances create unique states of consciousness by increasing the brain's information-processing flexibility. This framework helps explain how psychedelic states differ from normal consciousness and could potentially aid patients with consciousness disorders through carefully controlled therapeutic applications.
Abstract
Given their recent success in counseling and psychiatry, the dialogue around psychedelics has mainly focused on their applications for mental healt...
Experiences of microdosing psychedelics in an attempt to support wellbeing and mental health.
BMC psychiatry – March 14, 2023
Summary
Small doses of psychedelics like LSD and psilocybin may offer mental health benefits, according to users who carefully track their experiences. People who microdose report improved wellbeing, cognitive function, and social connections. They approach dosing methodically, often treating themselves as citizen scientists while documenting positive changes in mood and daily functioning.
Abstract
Microdosing psychedelic drugs is a growing phenomenon, but little is known about the experiences surrounding this. Research broadly suggests that p...
Psychedelics and schizophrenia: Distinct alterations to Bayesian inference.
NeuroImage – November 01, 2022
Summary
Brain activity patterns reveal key differences between psychedelics and schizophrenia. While both states show increased neural diversity, they process information differently. Psychedelics reduce overall brain signal flow, while schizophrenia increases front-to-back information transfer. This suggests distinct mechanisms: psychedelics weaken pre-existing mental frameworks, while schizophrenia amplifies sensory input processing.
Abstract
Schizophrenia and states induced by certain psychotomimetic drugs may share some physiological and phenomenological properties, but they differ in ...
Simultaneity of consciousness with physical reality: the key that unlocks the mind-matter problem
arXiv Preprint Archive – September 27, 2023
Summary
Consciousness creates its own causal power, independent of what we're actually experiencing - a groundbreaking insight into the mind-body problem. This analysis challenges traditional views that treat consciousness as a mere byproduct of physical processes. Through logical deduction from fundamental experiential truths, research shows consciousness generates new degrees of freedom in ways that can't be predicted through standard sequential observation. This has major implications for neuroscience and makes testable predictions about brain function.
Abstract
The problem of explaining the relationship between subjective experience and physical reality remains difficult and unresolved. In most explanation...
Consciousness: Here, There but Not Everywhere
arXiv Preprint Archive – May 27, 2014
Summary
While most physical systems process information, only some can truly experience consciousness. Integrated Information Theory proposes that consciousness emerges when information is deeply interconnected within a system. This groundbreaking framework in q-bio.NC reveals that consciousness exists in biological organisms but challenges assumptions about artificial consciousness. Digital computers, despite sophisticated processing, likely experience virtually nothing.
Abstract
The science of consciousness has made great strides by focusing on the behavioral and neuronal correlates of experience. However, correlates are no...
Occipital and left temporal instantaneous amplitude and frequency oscillations correlated with access and phenomenal consciousness
arXiv Preprint Archive – December 26, 2020
Summary
Brain activity patterns reveal how consciousness emerges! Scientists discovered specific brain regions that light up differently when we're consciously aware of something versus when information is processed unconsciously. Using advanced signal analysis, researchers found unique electrical patterns in the occipital and left temporal brain areas that correlate with conscious experiences, advancing our understanding of how the brain creates awareness.
Abstract
Given the hard problem of consciousness (Chalmers, 1995) there are no brain electrophysiological correlates of the subjective experience (the felt ...
Optimizing Integrated Information with a Prior Guided Random Search Algorithm

Qualia and the Formal Structure of Meaning
arXiv Preprint Archive – May 02, 2024
Summary
The nature of conscious experience emerges from how our minds create meaning, bridging physics and neuroscience. Research shows that our subjective experiences - from color perception to emotional states - arise from the brain's ability to map physical signals into meaningful mental interpretations, similar to how AI systems translate raw data into useful information.
Abstract
This work explores the hypothesis that subjectively attributed meaning constitutes the phenomenal content of conscious experience. That is, phenome...
Synaptic clock as a neural substrate of consciousness
arXiv Preprint Archive – February 18, 2020
Summary
Our perception of time isn't uniform - it varies based on what we're experiencing. New research in q-bio.NC reveals how our brain's synaptic mechanisms create these flexible "time windows" of consciousness. Different types of information processing require different durations to enter awareness, suggesting consciousness itself may be fundamentally based on change rather than static states. This finding helps explain why time seems to speed up or slow down during various experiences.
Abstract
In this theoretical work the temporal aspect of consciousness is analyzed. We start from the notion that while conscious experience seems to change...
Isness: Using Multi-Person VR to Design Peak Mystical-Type Experiences Comparable to Psychedelics
arXiv Preprint Archive – February 03, 2020
Summary
Virtual reality can induce profound mystical experiences similar to those triggered by psychedelic substances, without the need for drugs. A groundbreaking human-computer interaction (cs.HC) experiment showed that carefully designed VR environments can create transformative group experiences where participants perceive themselves as pure energy, fostering deep feelings of connection and transcendence. Data from 57 participants revealed emotional responses matching those reported in clinical studies of psilocybin and LSD.
Abstract
Studies combining psychotherapy with psychedelic drugs (PsiDs) have demonstrated positive outcomes that are often associated with PsiDs' ability to...
A Neuronal Noise Critique of Integrated Information Theory
arXiv Preprint Archive – December 06, 2021
Summary
Brain noise isn't just random static - it's essential for how we think and learn. New research challenges a major theory of consciousness by showing that neural "noise" actually helps our brains process information and make decisions. While traditional models suggested this background activity reduces mental clarity, experiments reveal that controlled neural variability is crucial for learning, visual recognition, and forming mental categories. This finding fundamentally reshapes our understanding of how consciousness emerges from brain activity.
Abstract
Integrated Information Theory (IIT) is an audacious attempt to pin down the abstract, phenomenological experiences of consciousness into a rigorous...
