Combining spatially-and time-resolved spectroscopies, we attempted to quantitatively
evaluate the contribution ratio of the partial mean pathlength of cerebral tissue to the …

The basic parameters for physiological measurements provided by near-infrared
spectroscopy are the local absorption and scattering coefficients. For the adult human head …

Abstract Near Infrared Spectroscopy (NIRS) is an optical technique that measures tissue
absorbance of light at several wavelengths in the 700-1000 nm spectral region. From the …

The influence of skin on the bias and reproducibility of regional cerebral oxygenation
measurements is investigated using cw near-infrared spectroscopy (NIRS). Receiving …

Near infrared (IR) spectroscopy can give continuous, direct information about cerebral
oxygenation in vivo by providing signals from oxygenated and deoxygenated haemoglobin …

It has been shown that near-infrared spectroscopy (NIRS) permits the assessment of
functional brain activation. 8, 9, 14, 21 Four studies were dedicated to the visual system …

Resolving for changes in concentration of tissue chromophores in the human adult brain
with near-infrared spectroscopy has generally been based on the assumption that optical …

Changes in optical properties of biological tissue can be examined by near-infrared
spectroscopy (NIRS). The relative transparency of tissues including the skull to near-infrared …

We present near-infrared spectroscopy measurement of absolute cerebral hemoglobin
concentration and saturation in a large sample of 36 healthy elderly (mean age, 85±6 years) …

Analysis of the optical intrinsic signal of an exposed cortex has been applied to
measurement of functional brain activation. It is important for accurate measurement of …
