We recently coined the term ‘aphantasia’ to describe the experience of people who lack a ‘mind's eye’ (Zeman, Dewar, & Della Sala, 2015), highlighting the features of lifelong aphantasia in a group of 21 individuals who had contacted us after reading a popular account of a related paper (Zeman et al., 2010) by Carl Zimmer in the science magazine Discover (Zimmer, 2010). Several consistent characteristics emerged: most participants discovered in their ‘teens or twenties, to their surprise, that… Expand
A world without imagination? Consequences of aphantasia for an existential account of self
ABSTRACT Aphantasia is a spectrum disorder, affecting the ability of otherwise healthy individuals to form voluntary or conscious mental images, and in some cases also any form of sensoryExpand
Aphantasia, imagination and dreaming
Aphantasia is a recently discovered disorder characterised by the total incapacity to generate visual forms of mental imagery. This paper proposes that aphantasia raises important theoreticalExpand
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. Expand
What is the relationship between Aphantasia, Synaesthesia and Autism?
TLDR
The relationship between aphantasia and two other neurodevelopmental conditions also linked to imagery differences: synaesthesia, and autism is investigated, finding thatSynaesthesia can be objectively diagnosed in aphantasics, suggesting visual imagery is not necessary for synaesthetic to occur. Expand
(A)phantasia and severely deficient autobiographical memory: Scientific and personal perspectives
TLDR
The story of how I became aware of my own lack of mental imagery and the accompanying deficit in my episodic memory is recounted, and how I have sought scientific understanding of these conditions and how they have affected my life. Expand
The image of memory: relationship between autobiographical memory and mental imagery in Korsakoff syndrome.
TLDR
It is demonstrated that autobiographical retrieval in Korsakoff syndrome is associated with the ability to retrieve (visual imagery) and manipulate mental images (spatial imagery), and spatial imagery in patients with KS and control participants. Expand
Exploring the relationship between grapheme colour-picking consistency and mental imagery
TLDR
Using the consistency score as a proxy measure of grapheme-colour synaesthesia, this work provides more evidence for the suggestion that synaesthetic experience is associated with enhanced mental imagery, even when participants are naive to the research topic. Expand
Individual Differences in Autobiographical Memory
TLDR
This review synthesizes an emerging body of research regarding individual differences in autobiographical memory and focuses on two syndromes that fall at the extremes of the 'remembering' dimension: highly superior autobiographies memory (HSAM) and severely deficient autobiographicalMemory (SDAM). Expand
Mental imagery in animals: Learning, memory, and decision-making in the face of missing information
TLDR
This work describes the behavioral and neurobiological studies investigating the use of a mental image, its theoretical basis, and its connections to current human cognitive neuroscience research on episodic memory, imagination, and mental simulations and provides insight into the mechanisms that mediate the flexible use of an image during ambiguous situations. Expand
The neural correlates of visual imagery vividness – An fMRI study and literature review
TLDR
FMRI was used to examine brain activation while participants looked at, or later imagined, famous faces and famous buildings, and revealed that the low-vividness group activated a more widespread set of brain regions while visualising than the high-violetness group. Expand

Is the Charcot and Bernard case (1883) of loss of visual imagery really based on neurological impairment?
TLDR
Although Monsieur X's damage was initially interpreted as neurological, reports of similar symptoms in the psychiatric field lead us to postulate a functional cause for his impairment as well. Expand
The “Psychogenic” Versus “Organic” Conundrum of Pure Retrograde Amnesia: Is it Still Worth Pursuing?
It is worth providing a definition to prevent any misunderstanding in the forthcoming comments. We will essentially concentrate on PRA for which arguments in favour of putative causal factorsExpand
Organic Retrograde Amnesia
It is of interest to comment upon the paper by Sella et al. (2002, this issue) in the light of Liepmann’s (1910) case report, although the relevance of the latter to the former is limited.Expand
Visual mental imagery in congenital prosopagnosia
TLDR
It is demonstrated that the cPA is a deficit of configural face processing, and it is suggested that the 'VVIQ-PA' (V VIQ-Prosopagnosia) questionnaire can help to confirm the diagnosis of cPA. Expand

Loss of retrograde memory, unaccompanied by the disruption of anterograde memory or at least disproportionate to its severity, is a clinical pattern repeatedly reported in the last twenty years,Expand
Loss of imagery phenomenology with intact visuo-spatial task performance: A case of ‘blind imagination’
TLDR
The case of a patient, MX, who abruptly lost the ability to generate visual images is described, indicating that successful performance in visual imagery and visual memory tasks can be dissociated from the phenomenal experience of visual imagery. Expand
The neurological basis of mental imagery: A componential analysis

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

This is the author’s version of a work that was accepted for publication in Cortex and may have been made to this work since it was submitted for publication. Expand
Neural correlates of the psychedelic state as determined by fMRI studies with psilocybin
TLDR
Psilocybin caused a significant decrease in the positive coupling between the mPFC and PCC, which strongly imply that the subjective effects of psychedelic drugs are caused by decreased activity and connectivity in the brain's key connector hubs, enabling a state of unconstrained cognition. Expand
