Adam Zeman

Adam Zeman is Honorary Professor of Cognitive and Behavioural Neurology at the University of Exeter Medical School and Honorary Fellow at the University of Edinburgh. He is best known for coining the term aphantasia in 2015 and subsequently identifying and naming hyperphantasia, the opposite extreme of exceptionally vivid mental imagery. His work has helped spark a rapidly expanding field of research into individual differences in mental imagery. His books include A Portrait of the Brain (Yale University Press, 2008), The Shape of Things Unseen (Bloomsbury, 2025), and, forthcoming, Phantasia (Allen Lane, UK; Basic Books, US).
