For the most part, anyone who wants to see what’s going on inside someone else’s brain has to make a tradeoff when it comes to which tools to use. The electroencephalograph (EEG) is cheap and portable ...

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.

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 ...

What unique processes conspire to create a healthy, functional human brain? How can we be so genetically similar to, say, chimpanzees, and yet be light-years more sophisticated cognitively and ...
