It is interesting but less so when you know that humans are mildly bioluminescent.

From the post:
>A new study published in iScience provides evidence that the human brain emits extremely faint light signals that not only pass through the skull but also appear to change in response to mental states. Researchers found that these ultraweak light emissions could be recorded in complete darkness, and they appeared to shift in response to simple tasks like closing the eyes or listening to sound. The findings suggest that this faint brain light may carry information about brain activity—possibly opening the door to a new way of studying the brain (photoencephalography).
It also goes the other way, with high intensity near infra-red light penetrating deep into brain tissue and directly stimulating neurons. The "science" boffins seem intent on using precise lasers or LED lights, but a roaring fire will do fine.
I always wondered why I've always heard that smart people were "bright."
Good one
