A Large-Scale Computer-Vision Mapping of the Geometric Structures of Stroboscopically-Induced Visual Hallucinations

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

Investigating the role of sensorimotor spatial dependencies in shaping conscious access to virtual 3D objects

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.

Modelling Phenomenological Differences in Aetiologically Distinct Visual Hallucinations Using Deep Neural Networks

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

Extensive Phenomenological Overlap between Induced and Naturally-Occurring Synaesthetic Experiences

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

Increased spontaneous EEG signal diversity during stroboscopically-induced altered states of consciousness

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 Hallucination Machine: A Deep-Dream VR platform for Studying the Phenomenology of Visual Hallucinations

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.

Theta-burst transcranial magnetic stimulation to the prefrontal or parietal cortex does not impair metacognitive visual awareness

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