Aphantasia and the Language of Imagination: A Wittgensteinian Exploration
Congenital aphantasia, or the complete absence of mental imagery, is a topic that has recently aroused the interest of researchers in many fields including philosophy, psychology and cognitive
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 sensory

In a recent article in this journal, Dos Santos et al. (2018) report a case of ayahuasca use by a man with aphantasia. This account is the first such report of the use of a psychedelic agent by
Aphantasia: The science of visual imagery extremes.
A cognitive profile of multi-sensory imagery, memory and dreaming in aphantasia
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.
Quantifying aphantasia through drawing: Those without visual imagery show deficits in object but not spatial memory
This large-scale online study of aphantasics revealed a dissociation in object and spatial content in their memory representations and provides evidence for separate systems in memory that support object versus spatial information.
A Preliminary Single-case Study of Aphantasia in
difficulties in perceiving/discriminating objects and faces and could read and write, although he could not create images. We assessed his imagery abilities, such as vividness, controllability, and
Mental imagery in animals: Learning, memory, and decision-making in the face of missing information
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.


Is the Charcot and Bernard case (1883) of loss of visual imagery really based on neurological impairment?
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.

Lives without imagery – Congenital aphantasia
Feeling unreal: a PET study of depersonalization disorder.
Depersonalization appears to be associated with functional abnormalities along sequential hierarchical areas, secondary and cross-modal, of the sensory cortex (visual, auditory, and somatosensory), as well as areas responsible for an integrated body schema.
Un cas de dépersonnalisation
Depersonalization names a symptom or syndrome often met with in psychiatric and neurological practice, and which is defined as: ’a feeling of being distant’, or ’not really here’. For example,
Where bottom-up meets top-down: neuronal interactions during perception and imagery.
This investigation revealed that neuronal interactions between occipito-temporal, parietal and frontal regions are task- and stimulus-dependent and mediated by content-sensitive forward connections from early visual areas.
