A close-up into the brain of a medical model of a human head. Most radiologists thought the idea was crazy. But one doctor was willing to listen.

Scientists reveal the brain emits faint light that reflects mental activity, opening a new path for non-invasive brain ...

They’ve detected photons that traveled from one side of an adult human head to the other—an optical journey spanning over 15 centimeters and requiring passage through skull, brain, and bone.

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 ...

For decades, scientists have used near-infrared light to study the brain in a noninvasive way. This optical technique, known as "fNIRS" (short for "functional near-infrared spectroscopy"), measures ...

Researchers at the University of Glasgow have achieved a milestone in brain imaging by detecting near-infrared light that traveled completely through an adult human head. Using high-powered lasers ...
