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.
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.
