As many as two million people in the United Kingdom repeatedly see people, animals, and objects that have no objective reality. Hallucinations on the border of sleep, dementing illnesses, delirium, eye disease, and schizophrenia account for 90% of these. The remainder have rarer disorders. We review existing models of recurrent complex visual hallucinations (RCVH) in the awake person, including cortical irritation, cortical hyperexcitability and cortical release, top-down activation… 

Tricks of the mind: Visual hallucinations as disorders of attention

Investigating visual misperceptions in Parkinson's disease: A novel behavioral paradigm

It is proposed that the BPP may offer a novel approach for exploring the neural correlates underlying visual hallucinations and misperceptions in PD, and patients with impaired performance on the B PP had higher rates of hallucinations, increased symptoms of RBD, and poorer performance on set shifting, suggesting disrupted processing within the attentional control networks.

Visual misperceptions and hallucinations in Parkinson's disease: Dysfunction of attentional control networks?

A novel hypothesis is proposed that hallucinations in PD reflect the relative inability to recruit activation in the dorsal attention network in the presence of an ambiguous percept, leading to overreliance on default mode network processing and salience arising from the ventral attention network.

Hallucinations: The Science of Idiosyncratic Perception

This book review the latest research on the cognitive and neural bases of hallucinations and outline their unique neurobiology by drawing on evidence from brain imaging and neurotransmission studies to put forward a comprehensive, multicomponent model of hallucinations.

The Phenomenology and Neurobiology of Visual Distortions and Hallucinations in Schizophrenia: An Update

The potential role of alterations at multiple points in the visual pathway, including the retina, the roles of multiple neurotransmitters, and the role of a combination of disinhibited default mode network activity and enhanced state-related apical/contextual drive in determining the onset and content of VH are emphasized.

Hallucinations as top-down effects on perception.

Visual hallucinations in Parkinson's disease: Theoretical models

This review considers the leading hypothetical frameworks for visual hallucinations in Parkinson's disease, summarizing the key aspects of each in an attempt to highlight the aspects of the condition that such a unifying hypothesis must explain.

Compensatory shifts in visual perception are associated with hallucinations in Lewy body disorders

The results suggest that participants with hallucinations compensate for perceptual deficits by relaxing perceptual criteria, at a cost of seeing things that are not there, and that visual cues regularize perception, which may provide a mechanism for understanding the interaction between environments and hallucinations.

The Subcortical Confinement Hypothesis: A Neurological Model for Schizotypal Hallucinations

Introduction: Different types of hallucinations are symptomatic of different conditions. Schizotypal hallucinations are unique in that they follow existing delusional narrative patterns: they are



Repeated visual hallucinations in Parkinson's disease as disturbed external/internal perceptions: Focused review and a new integrative model

This work suggests that VH should be considered as a dysregulation of the gating and filtering of external perception and internal image production and suggests new, testable hypotheses regarding their pathophysiology and therapy.

Cognitive basis of hallucinations in schizophrenia: role of top-down information processing

Properties of Complex Hallucinations Associated with Deficits in Vision

Combined use of multiple-correspondence analysis and hierarchical cluster analysis reveals a set of features that characterize the ‘typical’ Charles Bonnet hallucinatory experience that ranges from discrete perceptual experiences to multiple, changing experiences.

Complex visual hallucinations. Clinical and neurobiological insights.

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.

A man who described continuous visual hallucinations of object fragments in the left visual field following a stroke in the right occipital cortex was studied, who performed normally on standardized measures of visual perception and other cognitive abilities.

Auditory hallucinations: Failure to inhibit irrelevant memories

It is proposed that a combination of deficits in inhibition and (episodic) memory provides a useful model of AH, which can accommodate many of the characteristic features of the symptom and fits well with the neuroanatomical circuitry that is believed to underlie the occurrence of AH.

Visual command hallucinations in a patient with pure alexia.

Syntacto-semantic visual hallucinations may represent a separate category of textual hallucinations related to the cortical network implicated in the auditory hallucinations of schizophrenia, as the patient had a pure alexic syndrome, a known consequence of VWFA lesions.

Hallucinations in schizophrenia, sensory impairment, and brain disease: A unifying model

A unified pathophysiological framework for hallucinations in neurological and psychiatric conditions is proposed, which integrates previously unrelated neurobiological and psychological findings.
