Baby Thinking Radiologists Use Light To Scan The Inner Workings Of The Brain
December 1, 2007 — Radiologists have developed a new device to understand brain activity. It is a collection of fiber optic cables attached to a flexible cap placed atop the head. The cables send near-infrared light through the skull and into the brain, where it is diffused or scattered before it is collected by receiver cables. The device is able to interpret the light to measure blood circulation and the amount of oxygen in that blood, which helps explain brain activity.
