40 Hz Light and Brain Chemistry Research
Researchers at the Georgia Institute of Technology investigated how rhythmic 40 Hz light influences chemical signaling in the brain. Their findings showed that brief exposure to 40 Hz flickering light was associated with changes in cytokine activity—molecules involved in the brain’s communication and immune responses.
This study contributes to growing research on how gamma-frequency light interacts with brain chemistry and may help scientists better understand the biological processes linked with cognitive health.
