Takamura and colleagues · Cortex
Aphantasic individuals showed eye movement patterns similar to visualizers when exploring mental maps despite reporting no subjective imagery. This suggests aphantasia may reflect reduced metacognitive access to imagery rather than a total absence of representational content.
New and colleagues · Cortex
Aphantasia is linked to higher rates of neurodevelopmental, neurological, and psychiatric disorders compared to typical imagery. This highlights the need for multisensory evaluations and tailored interventions for neurodiverse profiles.
Monzel and colleagues · Cortex
People with aphantasia recalled fewer letters than others from a grid flashed for 50 milliseconds, but not from one shown for 5 seconds. This suggests imagery helps hold a split-second visual trace, while other strategies work given more time.
Bartolomeo and Arcangeli · Cortex
Researchers argue that congenital aphantasia is not "imagery blindsight" because individuals retain high-level accuracy and conscious access to information via non-visual routes. This suggests aphantasia involves a selective inability to format information into a quasi-visual experience.
Silvanto · Cortex
A commentary argues that whether to treat aphantasia depends on subtype. Imagery lost after trauma or stress is the clearest candidate, with care aimed at underlying problems; lifelong absent imagery without impairment is variation, not pathology.
Tomastikova and Silson · Cortex
Researchers found that mental imagery of people, but not buildings, significantly primed subsequent perception in a binocular rivalry task. This suggests that the functional impact of imagery on perception is category-specific rather than a universal effect.
Rollo and colleagues · Brain and Cognition
Bilateral temporal cortex stimulation significantly reduced the volitional control of auditory imagery while leaving vividness largely unaffected. This suggests that the ability to manipulate internal sounds relies on specific temporal-cortical dynamics distinct from those supporting image clarity.
Kutsche and colleagues · Cortex
Lesions causing aphantasia are all functionally connected to a specific region in the left ventral visual pathway called the fusiform imagery node. This provides causal evidence that this node's connections are key for voluntary visual imagery.
Gardner, Saurels and Arnold · Cortex
Researchers found that while imagining dark versus bright scenes modulates the pupillary response, this physiological change does not correlate with subjective imagery vividness ratings. This suggests pupillometry is not a reliable objective index for individual differences in imagery strength.
Lebon · Cortex
Individuals with aphantasia show decodable activity in early visual cortices during imagery tasks despite lacking conscious visual experience. This suggests that neural activation in V1 does not necessarily equate to subjective mental imagery.
Koenig-Robert, Keogh and Pearson · Cortex
Some people with aphantasia report gaining visual imagery after using psychedelics, possibly due to increased neural plasticity and connectivity. This sudden onset of imagery could increase the risk of intrusive thoughts and other mental health challenges.
Megla, Prasad and Bainbridge · Cerebral Cortex
Researchers found that an aphantasic twin had surprisingly similar brain activity to their imager twin during memory tasks despite lacking visual imagery. This suggests aphantasia may be a spectrum with more preserved visual information than previously thought.
Scholz, Monzel and Liu · Current Biology
Neural activity in aphantasia during imagery tasks lacks the perception-like representational overlap found in typical imagers. This suggests that neural activity in aphantasics reflects alternative non-perceptual strategies rather than unconscious mental imagery.
Liu and colleagues · Cortex
In a 7-tesla brain imaging study of 10 people with aphantasia and 10 typical imagers, attempted imagery activated similar visual areas in both groups. In aphantasia, a key imagery region was less connected with frontal and parietal areas.
Chang and colleagues · Current Biology
Researchers found that stimulus-specific information can be decoded from the early visual cortex of people with aphantasia during imagery attempts. This suggests that aphantasia involves a representational break between neural activity and conscious experience.
Arnold and colleagues · Cortex
Among university students, those who rated their imagery as less vivid were less likely to picture something, like a pink elephant, when told not to. This suggests weaker imagery may bring more resistance to unwanted images.
Zeman and colleagues · Cortex
Researchers define aphantasia as the absence of voluntary sensory imagery, often extending beyond vision to other modalities. This formal definition establishes a standardized framework for classifying multisensory and global imagery deficits.
Montabes de la Cruz and colleagues · Current Biology
Aphantasic individuals show reduced decoding of auditory information in the early visual cortex compared to sighted and blind controls. This suggests that aphantasia involves a broader impairment of top-down feedback to visual brain areas.
Cabbai and colleagues · Current Biology
In an fMRI study, the type of sound people with aphantasia heard could be decoded from their primary visual cortex, though they reported no imagery. A higher region, the precuneus, tracked whether imagery was experienced.
Milton · Current Biology
Aphantasia is linked to disrupted sensory representations in the primary visual cortex during voluntary imagery. This suggests that impaired feedback from higher-level brain regions to the visual cortex may cause the absence of a mental eye.
