Outline of Final Research Achievements

The purpose of this study was to develop a method for controlling sleep dynamics using noninvasive brain stimulation. We found that noninvasive brain stimulation at specific frequencies during sleep may improve subjective and objective sleep quality. In addition, we constructed a dynamic model of sleep stage transitions (Kishi et al., 2018). We also characterized altered sleep dynamics in patients with sleep bruxism (Kishi et al., 2020).
