A research group led by Project Associate Professor Yoshio Noda of the Department of Neuropsychiatry, Keio University School of Medicine, conducted a clinical study on healthy individuals using glasses that emit 40 Hz gamma-band violet light. They demonstrated for the first time in the world that this light stimulation, compared to 40 Hz white control light, induces brain wave changes that may be related to cognitive function.
This clinical study was conducted as a Phase I trial for a larger clinical study targeting patients with mild depression. In this study, we confirmed significant changes in brain waves due to short-term exposure to violet light and verified the safety of this light exposure.
The results of this research were published on June 15, 2021, in the interdisciplinary general journal "Journal of Personalized Medicine."
