A new set of techniques allows for the study of brain function by near‐infrared light,
exploiting two optical phenomena: Changes in light absorption are determined by changes …

Several functional near-infrared spectroscopy (fNIRS) studies report their findings based on
changes of a single chromophore, usually concentration changes of oxygenated …

Present implementations of near infrared spectroscopy permit the detection of signals
related to neuronal activity non-invasively through the intact skull (for review see: Chance …

Changes in optical properties of biological tissue can be examined by near-infrared
