Can We Measure Correlates of Neuronal Activity with Non-Invasive Optical Methods?987) and therefore penetrates several centimeters inside the head and other body structures. Thus, near-infrared light can be used to study absorption and scattering properties of living tissues. This includes non-invasive, quantitative spectroscopic measurements of the concentration of substances w

Cerebral Oxygenation States as Revealed by Near-Infrared Spectrophotometryitoring of tissue oxygenation. However, even now the quantification of hemoglobin signals and the knowledge of the redox behavior of cytochrome oxidase in vivo, as well as the measurement of cytochrome in the presence of normal blood circulation still pose unresolved issues.

Near-Infrared Spectroscopy in Functional Activation Studiesation in human adults.. If NIRS is to establish its place in functional brain research it must be proven that the changes monitored reflect the activation state of the cortex in response to a stimulus. This article gives an overview of the studies performed. On the basis of the reported findings and

Correlation between Absolute Deoxyhaemoglobin Measured by Near Infrared Spectroscopy (NIRS) anrd MR image contrast relies upon tissue differences in MR visible hydrogen spin density, spin-lattice (T1) relaxation and spin-spin (T2) relaxation. In soft tissue, the variation of MR visible hydrogen spin density between tissues types is small (up to 30%) whereas T1 and T2 relaxation times can var
