Outline of Final Research Achievements |
Perceptual learning is defined as an experience-dependent permanent and consistent change in the perception of a stimulus array, following practice with that array. In this study, we revealed individual differences in perceptual learning effects, which involved differences in alpha oscillation changes in the primary somatosensory cortex. Additionally, we examined whether transcranial alternating current stimulation of the primary somatosensory cortex at alpha frequency, which enhances neural alpha oscillation, could enhance the perceptual learning effect. The results suggested that the perceptual learning effect was not enhanced.

Academic Significance and Societal Importance of the Research Achievements |
これまでに,感覚機能を向上させるために,知覚学習を用いた介入手法が検討されてきた.本研究は知覚学習効果には個人差があり,その個人差を引き起こす要因のひとつに感覚情報を処理する皮質領域の律動活動が関与している可能性を示した.知覚学習効果の個人差を説明する要因については検討すべき事項が残されているが,今後さらなる検証を進めて,知覚学習効果を増強する介入方法を開発していきたい.
