This study shows psilocybin reorganizes brain activity into context-sensitive patterns linked to subjective experience and mindset changes.

The paper uses an unsupervised computer-vision pipeline to analyze drawings of stroboscopically induced visual hallucinations, identifying recurring and novel geometric patterns.

This study investigates how sensorimotor spatial dependencies affect conscious access to virtual 3D objects, finding no significant differences in breakthrough times across different coupling rules.

This study uses dynamical independence to analyze how different anaesthetics affect emergent neural dynamics in the human brain, revealing drug-specific changes in structure and organization.

This paper introduces Dynamical Independence (DI) to identify emergent macroscopic dynamics in a biophysical neural model by analyzing the balance between integration and segregation.

This study examines the electrophysiological state of the isolated cortex after hemispherotomy in awake humans, finding sleep-like activity without spindles.

This study examines how external stimuli modulate brain entropy during a psychedelic experience, finding that eye closure enhances entropy changes and that video stimuli disrupt the relationship between brain activity and subjective experience.

This paper uses deep neural networks to model and generate synthetic visual hallucinations that reflect distinct phenomenological characteristics of different aetiologies.

This paper introduces CSER, a new complexity estimator for neural signals that overcomes limitations of LZ by providing spectral decomposition and higher temporal resolution, revealing gamma band dominance and early entropy changes in consciousness states.

This study compares neural dynamics changes in schizophrenia and psychedelic-induced states using M/EEG data, finding distinct patterns in information transfer and Bayesian inference alterations.

The paper introduces a predictive processing model of time perception that incorporates memory, attention, and stimulus content, validated through experiments with 13,000 participants.

This paper uses Active Inference to simulate and model different forms of interoceptive control, including homeostatic, allostatic, and goal-directed, and their dysfunctions.

This study compares the phenomenological similarities between induced and naturally occurring grapheme-colour synaesthesia through qualitative analysis of interviews.

This study investigates the effect of dopamine D2 agonist cabergoline on conscious perception tasks and finds no significant impact on visual masking, attentional blink, or probabilistic discrimination.

The paper reconstructs trial-by-trial subjective time estimates from visual cortex BOLD activity during naturalistic video viewing, showing it reflects subjective experience rather than clock time.

This study examines changes in directed functional connectivity during the psychedelic state using MEG and finds a general decrease in directed connectivity for LSD, psilocybin, and low-dose ketamine.

This study investigates EEG signal diversity during stroboscopically-induced altered states of consciousness and finds increased diversity compared to wakeful rest, aligning with psychedelic state findings.

The paper shows humans can acquire and maintain multiple duration priors based on sensory signal type, both within and across senses.

This paper introduces a new behavioural measure of confidence, m-distance, that is invariant to decision bias and task performance, and demonstrates its robustness through computational simulations.

The paper investigates the Uniformity Illusion and finds that it does not result from changes in sensory encoding but depends on high-level processes.

This study proposes a model of human time perception based on perceptual classification, showing that an artificial neural system can estimate duration by tracking salient activation changes in response to natural scenes.

The paper introduces a VR platform using deep convolutional neural networks and panoramic videos to simulate visual hallucinations, showing it can replicate psychedelic-like experiences without causing temporal distortion.

This study investigates neurophysiological responses to duration and rhythm prediction violations across visual and auditory modalities, finding common supramodal mechanisms for duration prediction.

This study attempts to replicate findings that theta-burst TMS on DLPFC impairs metacognitive awareness but finds no such effect, highlighting methodological differences.
