Non–invasive techniques for the study of human brain function based on changes of the
haemoglobin content or on changes of haemoglobin saturation have recently been …

Near-infrared spectroscopy (NIRS) of the human brain is aiming at the non-invasive
determination of concentration changes of oxy-and deoxyhemoglobin in the cortex …

Abstract We used Monte Carlo simulations and the diffusion approximation to estimate
correction terms for the analysis of reflectance spectra of cortical intrinsic optical signals …

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 …

Near-infrared (NIR) spectroscopy has been used in studies of the cerebral hemodynamic
response to visual processing. In this paper, we present theoretical results from finite …

Near infrared spectroscopy (NIRS) is used to measure global changes in cerebral
haemodynamics. We have adapted the technique to measure regional changes in response …

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

Various factors, including variations in the concentration of hemoglobin, determine changes
in the transparency of living tissue to near‐infrared light. Hence, optical measures have …

Recent work aimed at providing an absolute measurement of tissue haemoglobin saturation
and a new instrument development, the spatially resolved spectrometer (SRS), are …

Using near–infrared spectroscopy, we investigated the time–course of the concentrations of
oxygenated haemoglobin,[oxy–Hb], and deoxygenated haemoglobin,[deoxy–Hb], in the …
