Cover Story: The study examines the influence of flashing light at the critical fusion frequency on cortical excitability in the human brain. An EEG recording revealed that selective chromatic flicker stimulation, combined with light scattering, enhances magnocellular stimulation and parvocellular pathway inhibition. This resulted in increased high-frequency brain oscillations (i.e., beta and gamma waves), indicating neuroplastic modulation. Furthermore, the article introduces a new non-invasive way to obtain the E/I ratio and a new metric to calculate the peak shift of the main frequency ranges. These results suggested that non-invasive visual flicker stimulation is a promising tool for rebalancing cortical excitation/inhibition dynamics and has therapeutic application for neurological and psychiatric diseases such as Alzheimer's, epilepsy, depression, and schizophrenia. View this paper
