Scientists found that neurons in mammalian brains were capable of producing photons of light, or “Biophotons”!

The photons, strangely enough, appear within the visible spectrum. They range from near-infrared through violet, or between 200 and 1,300 nanometers.

Scientists have an exciting suspicion that our brain’s neurons might be able to communicate through light. They suspect that our brain might have optical communication channels, but they have no idea what could be communicated.
