研究領域	触覚刺激の刺激方法の違いが大脳皮質の活動に及ぼす影響を明らかにする研究一定時間の触覚刺激介入が運動機能および感覚機能に及ぼす影響を明らかにする研究脳卒中患者に対する脳刺激効果の個人特性を明らかにする研究
研究紹介	日常生活の中で、我々は様々な刺激を感じながら生活しています。その中でも触覚（触った感覚）はとても重要な感覚の一つです。脳卒中などの疾患患者は触覚機能が低下していることが多く、この触覚機能の低下が運動機能の低下に結びついていると考えられています。しかしながら、その治療法は未だ確立されていません。そこで、我々は様々な触覚刺激（ツルツルやザラザラなど）介入が運動機能および感覚機能に及ぼす影響を明らかにする研究を行っています。これが明らかになれば、運動障害や感覚障害を持った患者様に対するリハビリテーションに応用できる可能性があると考えています。

Research Introduction	The cortical activity following the mechanical tactile stimulation depends on the tactile stimulation patterns, and prolonged mechanical tactile stimulation or non-invasive brain stimulation modulates the cortical excitability. Therefore, we investigated whether the effects of mechanical tactile stimulus intervention or non-invasive brain stimulation on somatosensory function and cortical function.
