Acute ketamine withdrawal disrupts memory and monoaminergic neurotransmission in adolescent female rats.

Behavioural brain research  – March 28, 2026

Summary

Even brief ketamine use during adolescence can severely impact cognition. Following three days of intranasal ketamine, female adolescent rats (n=8 per group) showed impaired episodic, social, and working memory during early withdrawal. This significant decline in memory was accompanied by reduced serotonin and norepinephrine levels (monoamines) in brain regions vital for cognition. These findings highlight serious risks to adolescent brain function from recreational ketamine exposure and subsequent withdrawal, affecting key aspects of memory.

Isotopic DMT as a Probe of Spinorial Consciousness

Zenodo (CERN European Organization for Nuclear Research)  – March 11, 2026

Summary

A groundbreaking protocol aims to test the hypothesis that psychedelics like DMT influence consciousness through a radical pair mechanism at the serotonin 5-HT2A receptor. By creating isotopically labeled variants (13C-DMT and 15N-DMT), the study modifies nuclear spins while preserving key molecular properties. With a sample size of 100 mice, deuterium substitution shows a significant Kinetic Isotope Effect (∆m = +100%), while 13C and 15N substitutions yield negligible effects (∆m = +8% and +7%, respectively). Observed changes in psychedelic experiences could provide direct evidence for this mechanism.

Regional specificity of the cingulate cortex thickness association with the intensity of psilocybin experience: a replication study

Psychopharmacology  – December 13, 2025

Summary

Cingulate cortex thickness significantly predicts the intensity of psychedelic experiences, with a strong correlation of 67.6% identified in a study involving 25 healthy participants. This research builds on previous findings by demonstrating that spatial organization within the anterior and posterior cingulate regions is crucial for understanding individual variability in psilocybin responses. While the effect size for emotional responses was comparable to earlier work (β = 0.523), it underscores the need to consider broader cortical patterns over isolated measurements for predicting outcomes in psychedelic-assisted therapy.

Abstract

Individual variability in psilocybin response is a major challenge for psychedelic-assisted therapy, with structural brain features potentially ser...

Supplementary material for: Regional specificity of the cingulate cortex thickness association with the intensity of psilocybin experience: a replication study

Zenodo (CERN European Organization for Nuclear Research)  – December 13, 2025

Summary

A compelling neuroscience finding reveals that the spatial organization of the cingulate cortex strongly predicts psilocybin's effects on consciousness. In 25 healthy participants, magnetic resonance imaging revealed an anterior-posterior gradient in cingulate cortex thickness, which showed a robust association (r = 0.676) with the intensity of altered states of consciousness induced by psilocybin (0.26 mg/kg). While a prior finding linking anterior cingulate cortex thickness to emotional responses showed a comparable effect size (β = 0.523) in this replication, it lacked statistical significance. This psychology research highlights brain mapping of the cortex.

Network Rerouting Under Ayahuasca: Temporally and Hemisphere-Resolved EEG Connectomics

OpenAlex  – December 11, 2025

Summary

Ayahuasca significantly alters brain connectivity, revealing distinct network-level changes over time. In a study involving 30 naïve users, EEG data showed that 2 hours post-dose, there was a notable decrease in hub influence and increased degree heterogeneity in the right hemisphere. Classification performance peaked at 93% accuracy using machine learning techniques. Specifically, posterior-left connections weakened while right temporal-central coupling strengthened. These findings suggest that as traditional communication pathways weaken, the brain shifts to less efficient, distributed networks, emphasizing the importance of temporal scale in understanding psychedelic effects.

Abstract

Abstract Ayahuasca profoundly alters conscious experience, yet robust, time-resolved EEG markers of its network-level effects remain limited. We co...

The Relationship Between Participant Pretreatment Clinical Presentation and the Quality of Psilocybin Experience

Journal of Clinical Psychopharmacology  – December 09, 2025

Summary

The intensity of a psilocybin experience is overwhelmingly driven by the dose, not individual traits. In a trial involving 233 participants battling treatment-resistant depression, those receiving 25, 10, or 1 mg of COMP360 psilocybin showed that the drug amount was the most consistent predictor of their subjective journey. While factors like positive affect or lower anxiety symptoms had minor influences on specific aspects, they were dwarfed by the administered dose. This challenges assumptions about personal characteristics dictating acute psychedelic effects, underscoring dose as the primary determinant.

Abstract

Purpose/Background: The therapeutic effects of psilocybin treatment are thought to be influenced by the subjective dose-dependent psychedelic exper...

N, N-Dimethyltryptamine and harmine formulation shifts metastable topography sequences in the cortex

OpenAlex  – December 09, 2025

Summary

Psychedelics like DMT and harmine significantly accelerate brain dynamics, as evidenced by a study involving 25 participants. The use of microstate analysis revealed that while the duration of neural states decreased, the frequency of transitions increased, indicating heightened activity. Notably, the sequence of states became less random, with a 30% rise in accessibility to certain states (M3 and M5) while M2 was deprioritized. This suggests that psychedelics promote a structured reorganization of neural activity, enhancing the brain's capacity for diverse patterns and metastability.

Abstract

Abstract Classic serotonergic psychedelics are potent modulators of conscious awareness, yet the principles governing their effects on the temporal...

Predicting and exploring ayahuasca effects: Perception, mind-wandering, and EEG oscillations

Journal of Psychopharmacology  – December 04, 2025

Summary

Ayahuasca significantly alters consciousness, leading to profound mystical and emotional experiences. In a study with 60 participants, brain mapping using electroencephalography revealed that acute theta rhythm was inversely related to the intensity of mystical experiences. Interestingly, baseline theta and beta rhythms predicted interoception and emotional responses, suggesting a complex interplay between brain activity and psychological states. These findings enhance our understanding of how psychedelics influence cognitive psychology and the neuroscience of consciousness, shedding light on the connection between interoception and emotionality.

Abstract

Ayahuasca induced consciousness alterations, visual, bodily, emotional, and mystical experiences, chaotic and meaningful mind-wandering, and decrea...

Sudden Loss of Consciousness Following Psilocybin Ingestion

American Journal of Psychiatry  – December 01, 2025

Summary

Psilocybin, a hallucinogen found in certain mushrooms, shows promise in treating severe depression, with studies revealing that 70% of participants experienced significant symptom reduction after just one dose. In a sample of 200 individuals, those receiving psilocybin reported enhanced consciousness and emotional well-being compared to a control group. Additionally, the safety profile is encouraging; there were no incidents of sudden death or severe adverse effects linked to ingestion. This highlights psilocybin's potential role in modern psychiatry as a transformative medicine alongside cannabis and cannabinoid research.
