Being no one, being One: The role of ego-dissolution and connectedness in the therapeutic effects of psychedelic experience
Journal of Psychedelic Studies – September 16, 2022
Summary
A review of 15 studies involving 2,182 participants reveals that psychedelic experiences promoting ego-dissolution and social connectedness significantly improve mental health. While ego-dissolution—a temporary shift in the ego's boundaries—initiates psychological change, sustained feelings of social connectedness offer a lasting positive affect. Clinical psychology can leverage these insights from Psychedelics and Drug Studies. Psychotherapists might emphasize ego-dissolution during preparation and foster social connectedness for integration, enhancing mental health outcomes and informing the broader narrative in social psychology.

Finding the self by losing the self: Neural correlates of ego-dissolution under psilocybin
Human Brain Mapping – May 22, 2015
Summary
The profound psychological experience of ego-dissolution, often induced by the hallucinogen psilocybin, is rooted in distinct brain alterations. A neuroscience study involving 15 healthy subjects revealed that psilocybin led to a feeling of "self" disintegration. This effect correlated with decreased functional connectivity between the medial temporal lobe and cortical regions, a "disintegration" of the brain's salience network, and reduced interhemispheric communication. These insights into Psychology and Psychedelics suggest the ego, vital for mental health and relevant to Psychiatry, relies on these neural systems.

DMT-induced shifts in criticality correlate with ego-dissolution
bioRxiv – February 08, 2025
Summary
Our brains operate at a unique "sweet spot" for processing information. This study explored if a powerful psychedelic, DMT, shifts this brain balance and how that relates to profound changes in self-perception. Researchers measured brain activity in participants given DMT, observing network behavior and subjective reports of ego-dissolution. Findings revealed DMT shifted brain activity away from this optimal balance, making it more chaotic. This change strongly correlated with participants reporting a profound loss of their sense of self. This directly links specific brain state changes to the subjective experience of ego-dissolution, offering new insights into consciousness.

Self unbound: ego dissolution in psychedelic experience
Neuroscience of Consciousness – January 01, 2017
Summary
Profound "ego dissolution" experiences from psychedelics challenge our understanding of the Self. This psychological phenomenon suggests our stable "I" is a useful cognitive fiction, a mental representation integrating diverse cognitive processing. This self-model performs a crucial function, unifying cognition across levels. Cognitive psychology and cognitive science propose this isn't merely a narrative, but a robust psychological mechanism. While it binds attributes, the self does not exist as an enduring entity. Psychedelic drug studies offer unique insights into the psychology of self, revealing the self-model's functional role.
Abstract
Users of psychedelic drugs often report that their sense of being a self or 'I' distinct from the rest of the world has diminished or altogether di...
Looking for the Self: Phenomenology, Neurophysiology and Philosophical Significance of Drug-induced Ego Dissolution
Frontiers in Human Neuroscience – May 23, 2017
Summary
High doses of hallucinogens strikingly dissolve the sense of self, a phenomenon, drug-induced ego dissolution. It challenges the psychology of self; consciousness doesn't always require self-awareness. Neuroscience identifies three drug classes inducing this, disrupting the "embodied self" rooted in multimodal sensory function, not just an illusion. Understanding these neural correlates of consciousness informs cognitive psychology and neurophysiology. It offers psychotherapists insights beyond ego depletion or narcissism, impacting cognition and pain management, akin to the placebo effect. This deep dive into the ego provides a unique lens for phenomenology.
Abstract
There is converging evidence that high doses of hallucinogenic drugs can produce significant alterations of self-experience, described as the disso...
Me, myself, bye: regional alterations in glutamate and the experience of ego dissolution with psilocybin.

LSD Relaxes Structural Constraints on Brain Dynamics and Default Mode Decoupling Tracks Ego Dissolution
OpenAlex – March 05, 2026
Summary
Psychedelics like LSD significantly alter brain function, revealing a remarkable decoupling of low-frequency brain activity from structural constraints. In a study involving 30 participants, LSD led to a 40% increase in flexibility within the default mode network, which is associated with ego dissolution. While low-frequency activity showed widespread reorganization, high-frequency gamma activity underwent selective adjustments. This suggests that psychedelics promote a unique rebalancing of neural dynamics, potentially enhancing therapeutic effects by loosening rigid structural limitations and improving communication among brain networks involved in self-awareness and perception.

Classic Psychedelics and Human–Animal Relations
International Journal of Environmental Research and Public Health – July 01, 2022
Summary
Profound ego dissolution during classic psychedelic experiences appears to significantly alter human-animal relations. Data from 2822 US adults, representative of diverse ethnic groups, shows ego dissolution strongly correlated with reduced speciesism (β = −0.17) and increased animal solidarity (β = 0.18), alongside a greater desire for animal welfare (β = 0.10). Lifetime psychedelic use also showed associations, though weaker. This work in social psychology and animal studies explores how altered states, relevant to the psychology of the 'ego', might shift our connection to other species. These findings, however, do not establish causality.

Consciousness alterations in a cohort of young Swiss men: Associations with substance use and personality traits.
Frontiers in psychiatry – January 01, 2022
Summary
Over 32% of 2,796 young Swiss men reported experiencing substance-induced altered states of consciousness, with 20.5% experiencing ego dissolution and 16.7% visual pseudo-hallucinations. Notably, former and current psychedelic users showed significant associations with all three types of altered states and perceived positive life influences. In contrast, sociability was negatively linked to these experiences. Additionally, higher anxiety-neuroticism correlated with ego dissolution and anxiety/paranoia, while sensation seeking was positively associated with both ego dissolution and visual pseudo-hallucinations, highlighting the complex interplay between personality traits and substance use.
Abstract
Substance-induced consciousness alterations (CA) have mainly been studied among users of psychedelics but not among people using street drugs. Expl...
Dissolving yourself in connection to others: shared experiences of ego attenuation and connectedness during group VR experiences can be comparable to psychedelics
arXiv Preprint Archive – May 17, 2021
Summary
Virtual reality can create profound experiences of connection and ego dissolution comparable to psychedelic drugs, but without substances. In groundbreaking human-computer interaction (cs.HC) research, participants experienced their bodies as luminous energy forms in shared virtual spaces, allowing them to merge and connect with others in unprecedented ways. Using four established measurement scales, these virtual experiences produced levels of self-transcendence and group bonding statistically similar to those reported in psychedelic studies.

With a growing body of research highlighting the therapeutic potential of experiential phenomenology which diminishes egoic identity and increases ...
Health Benefits and Positive Acute Effects of Psilocybin Consumption: A Quantitative Textual Analysis of User Self-Reported Data
Journal of Psychoactive Drugs – June 22, 2023
Summary
Profound mystical experiences driven by the hallucinogen psilocybin, including ego-dissolution, offer significant mental health benefits. An analysis of 846 public online self-reports revealed how context and setting profoundly shape these psychedelic experiences. The findings, relevant for clinical psychology and psychiatry, highlight somatic and visual alterations, connectedness, and cognitive shifts. Understanding these outcomes from a drug studies perspective is crucial for future psychotherapeutic applications, moving beyond basic biochemical analysis to inform safe and effective use of this alkaloid.

Classic psychedelic use and current meditation practice.
Mindfulness – April 01, 2023
Summary
People who have experienced psychedelics like LSD and psilocybin are more likely to maintain regular mindfulness meditation practices. A large U.S. study of over 2,800 people found that those who gained psychological insights during psychedelic experiences were especially drawn to both mindfulness and compassion-focused meditation practices, suggesting these substances may help cultivate lasting wellness habits.
Abstract
Previous research has investigated potential synergies between classic psychedelics and meditation practice, but relatively little remains known ab...
Persisting decreases in state and trait anxiety post-psilocybin: A naturalistic, observational study among retreat attendees
OpenAlex – March 02, 2022
Summary
Psilocybin-containing truffles produced rapid, lasting anxiety reductions in a supportive group setting. For 52 volunteers, consuming an average of 27.1 mg of psilocin, an alkaloid, led to medium to large decreases in state and trait anxiety, persisting for a week. This offers a promising avenue for clinical psychology and psychiatry, where current treatments yield 51-58% response rates. The powerful psychedelic experience, influencing neurotransmitter receptors, enhanced mindfulness and reduced neuroticism, impacting behavior and psychological well-being.

Decreases in State and Trait Anxiety Post-psilocybin: A Naturalistic, Observational Study Among Retreat Attendees
Frontiers in Psychiatry – July 07, 2022
Summary
Psilocybin, a psychedelic compound from truffles, significantly reduced anxiety in a supportive group setting. Among 46 participants, average psilocin consumption was 27.1 mg. State and trait anxiety measures showed medium reductions (effect sizes around 6) the morning after, persisting for a week (effect sizes around 7-8) in 23 individuals. This highlights psilocybin's potential in clinical psychology and psychiatry for anxiety management, possibly influencing neurotransmitter receptors. Mindfulness also increased, demonstrating broader psychological effects of psychedelics.
