(LinkedIn) In a review of 55 cases of cortical blindness, vivid imagery was repeatedly preserved despite complete or near-complete bilateral V1 damage. When imagery was impaired, lesions extended beyond V1, often into ventral temporal cortex. https://www.

Schematic representation of the double dissociation between cortical blindness and neurological aphantasia. Left: bilateral V1 damage causes cortical blindness but can spare visual mental imagery when ventral temporal regions, including the fusiform imagery node (FIN), and frontoparietal networks remain intact. Center: schematic summary of the proposed dissociation between the impaired visualperception pathway, dependent on V1, and the preserved imagery pathway, supported by interactions betwee…
