Outline of Final Research Achievements

We conducted 5 research projects to elucidate the determinants of individual differences in cognitive control, and to investigate the role of cognitive control in behavior control, working memory, pattern recognition, and visual awareness. Projects on mind wandering, visual working memory, diagram understanding, and binocular rivalry revealed various interactions between task specific brain regions (default mode network [DMN], parietal lobe, higher visual areas, etc.) and prefrontal regions, using fMRI, EEG, and tDCS techniques. A project on individual differences in cognitive control revealed the effects of genetic polymorphisms related to dopamine and acetylcholine functions on both behavioral interference in MSIT task, and on the pattern of functional connectivity among brain regions.
