Aphantasia prohibits people from experiencing visual imagery. While most of us can readily recall decade-old personal experiences (autobiographical memories, AM) with vivid mental images, there is a dearth of information about whether the loss of visual imagery in aphantasics affects their AM retrieval. The hippocampus is thought to be a crucial hu...

... found stark differences between the AM reports of the aphantasics and controls. Figure 1A and 1B display the comparison of the mean internal and external details between aphantasics and controls for their descriptions of remote and recent memories on the AMI. On average, 2-way ANOVA suggested that aphantasics described less internal details than controls, ...

... each subject, we then extracted fMRI signals during AM retrieval and MA. We found that aphantasics showed less AM-associated activation in all hippocampal parts (see Supplementary Material: Figure S1). ...

... showed reduced activation of bilateral hippocampi, F(17, 252) = 3.03, p < .001, including the left anterior, left posterior, right anterior, and right posterior hippocampus (see Figure S1). There was no laterality effect nor differences along the pattern of activation down the anteriorposterior axis between the groups (all ps > .05). ...

Individuals with aphantasia, a nonclinical condition typically characterized by mental imagery deficits, often report reduced episodic memory. However, findings have hitherto rested largely on subjective self-reports, with few studies experimentally investigating both objective and subjective aspects of episodic memory in aphantasia. In this study,...
