Task evoked EEG reveals neural processing differences in aphantasia.

ABSTRACT: Aphantasia, the inability to generate voluntary visual images, affects an estimated 3-4% of the population and provides a valuable model for examining how the brain supports cognition without imagery. Functional MRI studies have reported reduced coordination between visual and higher-order association areas involved in imagery control. However, the temporal characteristics of these neural differences remain unclear, as electroencephalographic (EEG) evidence limited to single-case studies. Here we present the first group-level EEG investigation of aphantasia, comparing 62 individuals with the condition to 59 controls during rest and tasks probing attention and working memory. In the oddball task, participants with aphantasia demonstrated smaller P300 amplitudes, an EEG index of attentional
