Unraveling the secret luminescence of the human brain
Turns out, our brains give off tiny flashes of light—called biophotons—while processing energy.
Researchers from Algoma University in Canada, led by biologist Hayley Casey, investigated this glow and think it could change how we track brain health.
TL;DR
How the study was conducted
Volunteers chilled in a dark room wearing EEG caps while super-sensitive detectors picked up these faint light signals.
The team found that the brightness changed with different brain states and wasn't just background noise.
Implications of the study
If scientists can read these light patterns, we might one day check on our brains without any needles or scans.
This could mean easier ways to spot issues early and learn more about how every person's brain works.
