When people lack visual imagination, this is known as aphantasia. Researchers investigated how the lack of mental imagery affects long-term memory. They were able to show that changes in two important brain regions, the hippocampus and the occipital lobe, as well as their interaction, have an influence on the impaired recall of personal memories in aphantasia.
