Dr. Merlin Monzel is a neuroscientist and one of the world’s foremost researchers on aphantasia — the condition where individuals live without the ability to visualize mental images.

For decades, millions of people didn’t know they were missing anything — until science caught up. Dr. Monzel’s groundbreaking work is revealing what happens when the mind’s eye goes dark, and how it changes memory, emotion, identity, imagination, trauma, and even consciousness itself.

Expect to learn what mental imagery is really for, why people with aphantasia can still dream vividly, how missing imagery affects autobiographical memory and emotional recall, why traditional therapy might fail aphantasic patients, how aphantasia might protect against PTSD, how memory becomes a script instead of a scene, what brain scans reveal about connectivity between the hippocampus and visual cortex, whether imagination can be trained or restored, and why studying aphantasia may offer deep insights into the nature of consciousness — and what makes us feel like a self at all.
