| Outline of Research at the Start |
本研究では、身体の揺動感覚を惹起する低周波前庭電流刺激が、睡眠の導入・促進効果を有するかを明らかにすることを目的とする。特に、睡眠中および睡眠前30分間の持続的前庭電流刺激が、それぞれ入眠過程の脳状態及び自律神経活動のダイナミクスに及ぼす影響を明らかにし、睡眠の質を改善し得るかを明らかにする。

| Outline of Final Research Achievements |
The purpose of this study was to determine whether galvanic vestibular stimulation has an effect on sleep onset and facilitation. Sleep was evaluated by polysomnographic recordings consisting of electroencephalography, electrooculography, and electromyography. The experiment was designed so that after the acclimation condition, the Stimulation and Sham conditions were performed in random order. Data analysis suggested that current stimulation of appropriate intensity to the vestibular systems had a sleep induction and facilitation effect in healthy young adults. In addition to these studies, we proposed a conceptual model of sleep dynamics in humans as a basis for sleep manipulation research using noninvasive brain stimulation and quantification of individual differences in sleep dynamics.
