People who experience visual imagination have pupillary responses that optimize the amount of light hitting the retina and change in response to imagined items. This pupillary response does not occur in those with aphantasia.
Do you experience difficulties conjuring up visual images in your mind while listening to spooky stories? You may have aphantasia, researchers report.
Pseudo-Hallucinations: Why Some People See More Vivid Mental Images Than Others – Test Yourself Here
Study reveals people who experience intense visual imagery during a Ganzflicker test have naturally lower frequency rhythms in the visual cortex, making them more susceptible to pseudo-hallucinations.
Aphantasia is marked by the inability to generate visual images in the mind's eye. Researchers explore the neurobiological basis for the disorder.
People with hyperphantasia, the ability to visualize vividly, have stronger connections between their visual brain network and decision-making networks. By contrast, those with aphantasia, an inability to visualize, have weaker connections between the brain regions.
Horror writers may have a hard time attracting those with aphantasia to read their spooky stories. A new study reveals those with aphantasia, a disorder marked by an inability to visualize mental imagery, have a hard time getting spooked by creepy stories. Findings suggest mental imagery may have a closer link to emotional processing and expression than previously believed.
While people with aphantasia lack visual imagery ability, they have intact spatial memory. Findings suggest mental imagery recall and spatial memory may be stored differently in the brain.
Aphantasia, a disorder in which people are lack the ability to mentally visualize imagery, is also associated with a widespread pattern of changes to other important cognitive processes. Many with aphantasia report a reduced ability to recall past events, imagine the future, and dream.
The strength of a person's mental imagery is associated with excitability in the prefrontal cortex and visual cortex. Highly excitable neurons in the visual cortex may reduce a person's ability to imagine mental images. The findings shed light on how aphantasia, a condition where a person can not imaging mental images, may occur.
Researchers are planning to conduct a new neuroimaging study to investigate why some people are unable to create visual images in their imagination.
Researchers report on why some people experience aphantasia, the inability to imagine in images.
Do you have a problem visualizing images? According to researchers, you could have a newly defined condition called aphantasia.
