Strange Luminescence Detected in Human Brains, According to New Research
In a groundbreaking study led by Dr. Nirosha Murugan, a Tier 2 Canada Research Chair in Biophysics at Algoma University, Ontario, the role of ultraweak photon emissions (UPE) in the human brain has been brought to light.
The study, which recruited 20 adults, aimed to investigate if the brain's UPE changes depending on what the brain is doing. During simple tasks like opening and closing their eyes and listening to sound recordings, the brains emitted this light in slow rhythmic patterns, at a frequency slower than once per second, that seemed to steady over the course of each two-minute task [1][3][5].
These faint light emissions, trillions of times weaker than a light bulb, are produced continuously by metabolic and oxidative processes within brain cells. As excited molecules return to resting states, they emit UPE [3][5]. The brain, which accounts for approximately 20% of the body's total energy, emits more UPE than most other tissues due to its intense metabolic activity and abundance of light-sensitive molecules like flavins and serotonin [3][5].
The potential implications for neuroscience and brain disorders are significant. UPE could offer a new passive way to monitor brain activity (photoencephalography), detecting brain states without electrodes or invasive tools [1][5]. Variations in UPE might allow early detection of neurological disorders such as epilepsy, dementia, or depression by revealing underlying changes in brain metabolism or oxidative stress [1].
Researchers hypothesize that UPE may not be merely a metabolic byproduct but possibly involved in cell communication within the brain, opening a "hidden dimension" to understanding brain function [1][3]. Changes in UPE emissions correlate with age and oxidative stress, potentially providing biomarkers for brain aging or pathology [3][5].
UPEs travel through the skull, raising the possibility that they could influence other brains in the environment. Dr. Murugan hopes her team's findings will initiate new conversations about the role of light in brain function [6].
Dr. Murugan, an assistant professor in the Department of Health Sciences at Wilfrid Laurier University in Ontario, Canada, believes that studying UPE could reveal a hidden dimension of the inner workings of our minds [4]. Measuring UPE offers a promising frontier for neuroscience research with potential for advancing brain diagnostics and understanding fundamental brain processes related to cognition and disease [1][3][5].
