Your Brain Is Glowing, and Scientists Can't Figure Out Why

Researchers have detected biophotons emitted by the human brain from outside the skull for the first time. The study found that emissions changed when participants switched between cognitive tasks, suggesting a potential role for these ultraweak photon emissions (UPEs) in brain function. While brain activity and biophoton emissions weren't directly correlated, the findings indicate a complex relationship between cognition and light production in the brain. This discovery raises new questions about biophotons in neural processes and may lead to novel non-invasive ways to measure brain activity.
