The Takeaway
Visualizing a memory requires a feedback signal to travel backward to the brain's visual center, acting like an internal projector. This study shows that in people with aphantasia, this connection is disrupted, meaning they can remember facts about an object but cannot 'see' it.
From the abstract
Working memory (WM) provides a mental sketchpad for simulating sensory experiences associated with mnemonic content. A critical unresolved question is how the brain generates the subjective sensory experience of these internal simulations. Here, we studied individuals with aphantasia, who report a subjective inability to generate visual imagery despite normal WM performance, providing a unique dissociation between objective WM performance and conscious subjective experience.
