Outline of Final Research Achievements

The primary goal of the research was to determine the changes in brain activity induced by transcranial direct current stimulation (tDCS) that are related to facilitation in behavioral performance during training on various tasks. The three tasks that are studied includes 1. A visual search task, 2. A guitar improvisation task, and 3. An airplane landing task. All of these studies employed a pre- and post- training session in which tDCS was given for approx. 30 minutes while feedback training was employed in either real stimulation or sham stimulation conditions. Even though we did not find an overall performance facilitation by tDCS, the results of these studies did find interesting changes in brain activity in some individuals that were related to facilitating performance. Essentially behavioral performance facilitation could be predicted in individuals in the tDCS stimulation group based on the degree of modulated brain activity but could not be predicted in the tDCS sham group.

Academic Significance and Societal Importance of the Research Achievements

一般的に、経頭蓋直流電気刺激(tDCS)は、様々な知覚、運動、認知課題のパフォーマンスや学習促進に有効であると考えられているが、本研究によりパフォーマンスの促進については差異があることがわかった。パフォーマンスの促進は脳活動の識別可能な変調によって特徴付けられることから、当該促進に関与する脳回路を特定したという点で学術的に重要である。また、学習効果向上ために個人特有の刺激パラダイムを調節したり、認知障害や精神障害等の治療に用い得ることから、社会的意義がある。tDCSの限界と、行動パフォーマンス促進の成功に相関する基礎的な脳活動の理解を深めることで、より良い新たなtDCSの実施が可能となる。
