GLASGOW — Doctors may be a step closer to peering deep into your brain to spot strokes or tumors without expensive MRI machines or invasive procedures. That’s because researchers at the University of ...

To achieve this, the team used powerful lasers and highly sensitive detectors in a carefully controlled experiment. They directed a pulsed laser beam at one side of a volunteer's head and placed a ...

They directed a pulsed laser beam at one side of a volunteer's head and placed a detector on the opposite side. The setup was designed to block out all other light and maximize the chances of catching ...

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 ...

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 imaging.
