The capacity for imagery, enabling us to visualise absent items and events, is a ubiquitous feature of our experience. This paper describes the case of a patient, MX, who abruptly lost the ability to generate visual images. He rated himself as experiencing almost no imagery on standard questionnaires, yet performed normally on standard tests of perception, visual imagery and visual memory. These unexpected findings were explored using functional MRI scanning (fMRI). Activation patterns while… Expand
The human imagination: the cognitive neuroscience of visual mental imagery
  • J. Pearson
  • Psychology, Medicine
  • Nature Reviews Neuroscience
  • 2019
TLDR
Recent insights into the neural mechanisms that underlie visual imagery are discussed, how imagery can be objectively and reliably measured, and how it affects general cognition are discussed. Expand
Visual and Motor Mental Imagery After Brain Damage
This chapter presents evidence from brain-damaged patients relevant to the debate concerning the neural underpinnings of visual and motor mental imagery capacities. For visual mental imagery, theExpand
A cognitive profile of multi-sensory imagery, memory and dreaming in aphantasia
TLDR
It is shown that compared to control participants with imagery ability, aphantasic individuals report decreased imagery in other sensory domains, although not all report a complete lack of multi-sensory imagery, suggesting a constructive role for visual imagery in representing episodic events. Expand
Hemispheric asymmetries in visual mental imagery.
TLDR
A critical review of the available literature on the hemispheric laterality of visual mental imagery, by looking at cross-method patterns of evidence in the domains of lesion neuropsychology, neuroimaging, and direct cortical stimulation suggests that visualmental imagery relies on large-scale brain networks, with a crucial participation of high-level visual regions in the temporal lobe. Expand
Visual working memory performance in aphantasia
TLDR
The results indicate that although a lack of mental imagery can be compensated for under some conditions, mental imagery has a functional role in other areas of visual cognition, one of which is high-precision working memory. Expand
Aphantasia: The science of visual imagery extremes.
TLDR
Preliminary evidence suggests that lifelong aphantasia is associated with prosopagnosia and reduction in autobiographical memory; hyperphantasia are associated with synesthesia; and aphantasic individuals can be highly imaginative and complete many tasks that were previously thought to rely on visual imagery, demonstrating that visualization is only one of many ways of representing things in their absence.

Visual mental imagery engages the left fusiform gyrus, but not the early visual cortex: a meta-analysis of neuroimaging evidence
TLDR
A revised neural model of VMI is proposed that draws inspiration from recent cytoarchitectonic and lesion studies, whereby fronto-parietal networks initiate, modulate, and maintain activity in a core temporal network centered on the fusiform imagery node, a high-level visual region in the left fusodus gyrus.

TLDR
A revised neural model of VMI is proposed that draws inspiration from recent cytoarchitectonic and lesion studies, whereby fronto-parietal networks initiate, modulate, and maintain activity in a core temporal network centered on the fusiform imagery node, a high-level visual region in the left fusodus gyrus.

The differential contributions of visual imagery constructs on autobiographical thinking
TLDR
The results indicate that while object imagery was significantly correlated with several phenomenological characteristics, such as the level of sensory and perceptual details for past events – but not for future events – spatial imagery predicted thelevel of episodic specificity for both past and future events. Expand
The Architect Who Lost the Ability to Imagine: The Cerebral Basis of Visual Imagery
TLDR
The neuropsychological data from an architect who lost his ability for visual imagery following a bilateral posterior cerebral artery (PCA) stroke is reported and it is suggested that these areas, and perhaps the region in the left fusiform gyrus, play an important role in the cerebral network involved in visual imagery.

The neural correlates of visual mental imagery: An ongoing debate
TLDR
Double dissociation in brain-damaged patients provides a strong challenge to models postulating a functional and anatomical equivalence of perception and imagery, and suggests that these functions have partly distinct neural correlates. Expand
The Relationship Between Visual Perception and Visual Mental Imagery: A Reappraisal of the Neuropsychological Evidence
TLDR
Artistic evidence suggests that occipital damage is neither necessary nor sufficient to produce imagery deficits, and that visual mental imagery abilities might require the integrity of brain areas related to vision, but at a higher level of integration than previously proposed. Expand
Multiple-domain dissociation between impaired visual perception and preserved mental imagery in a patient with bilateral extrastriate lesions
TLDR
The results suggest that mental imagery abilities need not be mediated by early visual cortices, and provide evidence to support the view that visual perception and visual mental imagery are subserved by independent functional mechanisms, which do not share the same cortical implementation. Expand
Unilateral neglect restricted to visual imagery
TLDR
A patient with a persistent disorder in visual imagery for familiar piazzas in the absence of any neglect for stimuli located in a far or near space or on his own body is described. Expand
Selective deficit of mental visual imagery with intact primary visual cortex and visual perception
TLDR
This study indicates that visual imagery deficits can occur independently from deficits of visual perception; visual imagery deficit can occur when the primary visual cortex is intact and the left temporal lobe plays an important role in visual mental imagery. Expand

TLDR
An attempt to interpret the patterns of deficits and preserved abilities in reports of loss of mental imagery following brain damage in terms of a componential information-processing model of imagery found a consistent pattern of deficit in a subset of patients. Expand
Effects of peripheral and central visual impairment on mental imagery capacity
TLDR
Interestingly, in brain-damaged patients, neurovisual disorders following occipital or parietal lesions are not systematically associated with representational deficits, thus demonstrating that visual perception and visual imagery may not rely on the same cortical structures as previously hypothesized.

Intact visual imagery and impaired visual perception in a patient with visual agnosia.
TLDR
A model in which imagery and perception are strongly associated but are also functionally specialized is proposed, in which C.K. was able to draw objects in considerable detail from memory, and his knowledge of the visual appearance of objects was preserved on a variety of mental imagery tasks.
