Researchers found that visual imagery recruits ventral and dorsal streams, with deficits often caused by white-matter disconnection. This suggests aphantasia is a network-level condition where higher-order systems fail to engage visual representations.

Engineered pareidolia functions as externally scaffolded mental imagery where minimal visual cues recruit internal templates. This provides a quantifiable bridge between creative perception, imagination, and clinical neuropsychology.

An architect who said his imagery had been vivid lost almost all of it after a stroke on both sides of the back of the brain, scoring close to the lowest possible score on an imagery questionnaire. He also had trouble recognizing faces and seeing colors, yet four other stroke patients, including another architect, kept their imagery although their test results largely overlapped with his. Brain scans showed only small areas in the right lingual gyrus and left fusiform gyrus damaged in him alone, so the authors propose these, especially the left fusiform area, as candidate regions for visual imagery.
