Outline of Final Research Achievements

We investigated the brain information processing underlying eidetic imagery using functional neuroimaging methods (NIRS and fMRI). In addition, an intensive interview and self-report measures of the image abilities of eidetic imagers were used. Our study yielded the following new findings. (1) Eidetic imagers have an extremely high object imagery ability controlled by the ventral pathway and relatively lower spatial imagery ability controlled by the dorsal pathway. (2) Strong eidetic imagers are mostly synesthetes. (3) Our functional neuroimaging data revealed that eidetic evocation is associated with strong activation of the prefrontal area and visual area in the occipital lobe in a fNIRS study. Contrary to our expectation, however, we found no evidence for involvement of the V1 in the evocation of eidetic images in a fMRI study. Based on these findings, a hypothetical brain model of eidetic imagery was introduced.
