Outline of Final Research Achievements

In this study, we investigated the effects of fMRI neurofeedback on EEG. We used an Oddball task with simple visual stimuli, in which stimuli were presented only in the right/ left visual field while the subject was gazing at the fixation point, and the number of rare stimuli was counted. The fMRI neurofeedback was performed on the V1 of only one of the left and right visual fields. The same task was performed in the left and right visual fields, and modulated ERPs were measured in the same areas.

Academic Significance and Societal Importance of the Research Achievements

fMRIニューロフィードバックによるERPへの影響の知見が得られた。結果からニューロフィドバックの効果の限局が可能な点、困難な点があることが推測される。同様の研究を続けることで、特定の認知機能の強化・減弱などが行えるようになることで今後の高齢化社会における認知機能関連の障害などにおいて効果的な治療手法の創出に繋がる可能性がある。
