Visual hallucinations can occur in healthy subjects during prolonged visual deprivation. We investigated the visual percepts and the associated brain activity in a 37-year-old healthy female subject who developed visual hallucinations during three weeks of blindfolding, and then compared this activity with the cortical activity associated with mental imagery of the same patterns. We acquired fMRI data with a Siemens 3T Magnetom Allegra towards the end of the deprivation period to assess… Expand
Visual imagery and visual perception induce similar changes in occipital slow waves of sleep
TLDR
Preliminary results demonstrate that short-term alterations in visual experience may trigger slow wave changes in cortical visual areas and suggest that plasticity-related EEG changes during sleep may reflect externally induced (‘bottom-up’) visual experiences, as well as internally generated processes. Expand
Visual imagery and visual perception induce similar changes in occipital slow waves of sleep.
TLDR
It is demonstrated that short-term alterations in visual experience may trigger slow-wave changes in cortical visual areas and suggested that plasticity-related EEG changes during sleep may reflect externally induced ("bottom up") visual experiences, as well as internally generated ("top down") processes.

The neural mechanisms of hallucinations: A quantitative meta-analysis of neuroimaging studies
TLDR
The need for unified theoretical frameworks that account for the full range of hallucinatory experiences is discussed, with greater activity in auditory cortex during AVHs and in visual cortex during VHs supports models proposing over-stimulation of sensory cortices in the generation of these perceptual anomalies. Expand
Individual differences shape the content of visual representations
TLDR
The evidence for the pictorial content of visual representations activated for VI, VWM, and preparatory templates is reviewed, and the importance of accounting for various individual differences in conducting research on this topic is highlighted. Expand
Fantasy, dream, vision, and hallucination: Approaches from a parallactic neuro-psychoanalytic perspective
ABSTRACT In this paper, we present a model of a specific category of complex thought and memory processes – figurative representations – which are viewed from a parallactic, psychoanalytic andExpand
Hallucinations on demand: the utility of experimentally induced phenomena in hallucination research
TLDR
It is argued that experimentally induced phenomena can bring hallucinations within reach of more objective behavioural and neural measurement and suggested that existing strategies that group pathological hallucinations into meaningful subtypes based on hallucination characteristics can guide extrapolation from hallucination models to other hallucinatory phenomena. Expand
Orientation-Specific Aftereffects to Mentally Generated Lines
TLDR
This study replicated the previously detected direct TAE induced by line imagination with altered design-variations to control possible perceptual task confounds and tried to induce two other orientation-specific aftereffects: indirect TAE and contrast-threshold elevation aftere affect by mental imagery.

Information gain in the brain's resting state: A new perspective on autism
TLDR
It is proposed that the excessive production of information in the absence of relevant sensory stimuli or attention to external cues underlies the cognitive differences between individuals with and without autism. Expand
Olfactory input is critical for sustaining odor quality codes in human orbitofrontal cortex
TLDR
It is shown that a 7-d period of olfactory deprivation induces reversible changes in odor-evoked fMRI activity in piriform cortex and orbitofrontal cortex and this suggests that transient changes in these key OFC regions are instrumental in sustaining odor perception integrity in the wake of disrupted sensory input. Expand
The “Bottom-Up” and “Top-Down” Components of the Hallucinatory Phenomenon
This chapter provides an overview of the literature on bottom-up and ­top-down processes that have been suggested as mechanisms in the generation and/or perpetuation of hallucinations, both in theExpand

TLDR
It is indicated that rapid and complete visual deprivation is sufficient to induce visual hallucinations in normal subjects. Expand
Mechanisms of migraine aura revealed by functional MRI in human visual cortex
TLDR
High-field functional MRI with near-continuous recording during visual aura in three subjects observed blood oxygenation level-dependent signal changes that strongly suggest that an electrophysiological event such as CSD generates the aura in human visual cortex. Expand
The anatomy of conscious vision: an fMRI study of visual hallucinations
TLDR
Functional magnetic resonance imaging is used to study patients with the Charles Bonnet syndrome to find that hallucinations of color, faces, textures and objects correlate with cerebral activity in ventral extrastriate visual cortex, that the content of the hallucinations reflects the functional specializations of the region and that patients who hallucinate have increased ventralside activity, which persists between hallucinations.

TLDR
Previously overlooked neuropsychological evidence on the relation between imagery and perception is reviewed, and its relative immunity to the foregoing alternative explanations is discussed. Expand
A functional neuroanatomy of hallucinations in schizophrenia
TLDR
A group study of five patients with classic auditory verbal hallucinations despite medication, demonstrating activations in subcortical nuclei (thalamic, stri-atal), limbic structures (especially hippocampus), and paralimbic regions (parahippocampal and cingulate gyri, as well as orbito-frontal cortex).

TLDR
It is suggested that perturbation of a distributed matrix may explain the production of similar, complex mental phenomena by relatively blunt insults at disparate sites. Expand
[Spatial misperceptions in amblyopic vision: abnormal activation of the primary visual cortex?].
TLDR
The results of the imaging experiment suggest that the occurrence of spatial distortions might explain the higher activation in the primary visual cortex of some amblyopic subjects, and suggests an involvement of higher-order, extrastriate visual areas of the dorsal, "where" visual pathway in amblyopia.
