“When you go all the way across the head, you’re at such low light levels that simply the color of your skin or thickness of your skull or the hairstyle that you have can make that difference of being ...

The team successfully detected photons transmitted through an entire adult human head (15.5cm diameter) with an attenuation factor of ~10^18, detecting approximately one photon per second.

The brain of the average adult weighs about 3 pounds; approximately 60 percent of that is fat, and the remaining 40 percent is a combination of water, protein, carbohydrates, and salts. It’s ...

Detecting photons through an entire adult head explores the limits of photon transport in the brain, for access to regions of the brain currently inaccessible with noninvasive optical brain ...

Scientists have developed a new technique for non-invasive brain imaging – and it involves shining light all the way through the head, from one side to the other. Currently the best portable, low-cost ...
