Functional neuroimaging. Optical approaches.
Optical methods assess different types of light tissue interactions such as light absorption, fluorescence, phosphoresence, scattering, and Doppler shift. In this article, it is reviewed how these different types of light-tissue interactions can be measured and how these measurements can be related to brain function. Based on these considerations, a new classification scheme of functional optical methods is proposed.
