Professor Adam Zeman is a Neurologist at the University of Exeter and the scientist who coined the term aphantasia — the “blind mind’s eye” — after a patient suddenly lost the ability to visualize following heart surgery.

Since then, he has led the global investigation into why some minds picture nothing while others see in IMAX 8K, uncovering what this hidden spectrum of imagination reveals about memory, dreams, emotion, creativity, and even consciousness itself. He is also the author of Consciousness: A User’s Guide, A Portrait of the Brain, and The Shape of Things Unseen.

Expect to learn why up to 5% of people can’t form mental images, how hyperphantasia floods the mind with cinema-like detail, why imagination is our brain’s “default mode,” how differences in the mind’s eye shape autobiographical memory and emotional vividness, why aphantasics still dream in pictures, what hallucinations and delusions reveal about the creative brain, how imagination connects to empathy and storytelling, the cultural impact of naming aphantasia, and much more
