Brain Emits Light: New Study Explores Monitoring Potential
Imagine your brain is like a lightbulb, but instead of bright light, it emits very faint light signals.
Scientists have found these tiny light emissions, called UPEs, coming from the human brain.
They studied people in the dark and noticed the light changed when people did different things like closing their eyes or hearing sounds.
This research could lead to new ways of watching how the brain works without needing to open someone's head.
It is still early research, but this new technique might help doctors understand and treat brain problems in the future.
Scientists discovered that the human brain emits faint light signals.
These ultraweak photon emissions (UPEs) may fluctuate with mental activity.
The study involved 20 healthy adults in total darkness using light-sensitive sensors.
Researchers observed rhythmic patterns in light emissions, especially with visual and auditory processing.
The findings suggest UPEs could offer a new way to monitor brain function.
- Who
- Researchers from Algoma University, Tufts University, and Wilfrid Laurier University led the study.
