Hallucinations in medical conditions

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.

Unreal? A Behavioral, Physiological, and Computational Model of the Sense of Reality

This study investigates the Sense of Reality through virtual reality simulations, finding that it varies with hallucination magnitude and is linked to physiological responses and a computational model comparing sensory input to an internal world model.

Not enough pleasure? Influence of hallucination proneness on sensory feedback processing of positive self-voice

The paper investigates how hallucination proneness affects attentional control and sensory feedback processing of positive self-voice using EEG, finding no significant modulation by HP.

Flicker and Ganzfeld induced visual hallucinations differ in frequency and content

This study compares flicker and Ganzfeld techniques to determine if they share a common mechanism for inducing visual hallucinations, finding similar patterns in frequency and complexity.

EEG resting state alpha dynamics predict individual proneness to auditory hallucinations

The paper uses EEG resting state alpha dynamics to predict individual proneness to auditory hallucinations by analyzing brain state occupancy and duration.

Resting State Neural Networks at Complex Visual Hallucinations in Charles Bonnet Syndrome

The paper investigates resting state neural networks in Charles Bonnet Syndrome patients compared to those with visual loss and healthy controls, finding decreased and increased connectivity in specific brain regions.

Brain Networks Detectable by fMRI during On-Line Self Report of Hallucinations in Schizophrenia

The paper analyzes fMRI data to identify brain networks involved in radio speech listening and hallucination experiences in schizophrenia, finding speech-duration-dependent responses but not hallucination-duration-dependent ones.

Sensorimotor hallucinationsin Parkinson's disease

This study uses robotics to induce hallucinations in Parkinson's disease patients and identifies a disrupted neural network associated with sensorimotor hallucinations.

Neural activity precedes conscious awareness of being in or out of a transient hallucinatory state

The paper shows that neural activity in the ventro-medial frontal cortex precedes conscious awareness of entering or exiting a transient hallucinatory state.
