After his mother’s death, Alex Wheeler felt guilty about how quickly he was able to move on from the initial shock, especially when compared with his siblings. His perspective on his emotions would come into clearer view when, by chance, he learned of a newly coined neurological phenomenon known as aphantasia, in which individuals are unable to generate images in their mind’s eye. In the short documentary Out of Mind, Wheeler retells his story and connects with the UK neurologist Adam Zeman, whose pioneering research on aphantasia gave it a name and brought it into public view, and the UK artist Amy Right, who also has aphantasia. Through Wheeler’s story, the UK filmmaker Simon Mulvaney explores the fascinating connections between images and emotions at the brain level.
