Functional Neuroimagingift. 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.

Signal Sources in PETnly tracer amounts of indicator substances are used, not only blood flow and energy metabolism can be measured, but also neurotransmitter synthesis (e.g., dopa decarboxylase activity with .F-6-fluoro-L-dopa) and neuroreceptor binding capacity (many tracers, most frequently labeled with .F or .C have
