In healthy human adults, cerebral concentrations of oxygenated hemoglobin ([HbO 2]) and
deoxygenated hemoglobin ([HbR]) were assessed during brain activation using near …

We used near-infrared spectroscopy (NIRS) to study noninvasively the influence of aging on
changes in the local concentration of oxygenated hemoglobin ([HbO2]), reduced …

Near-infrared spectroscopy (NIRS) is an optical method which allows non-invasive in vivo
measurements of concentration changes of oxygenated hemoglobin (O2Hb) and …

Near infrared spectroscopy (NIRS) is a new technique that permits noninvasive monitoring
of cerebral blood and tissue oxygenation. Recently, we and others have shown that NIRS …

Near-infrared spectroscopy (NIRS) was originally designed for clinical monitoring of tissue
oxygenation, and it has also been developed into a useful tool in neuroimaging studies, with …

Near‐infrared spectroscopy (NIRS), a noninvasive optical technique, can measure changes
in hemoglobin (Hb) concentrations in brain tissue. Jöbsis first described the in vivo …

Papers from four different groups were published in 1993 demonstrating the ability of
functional near infrared spectroscopy (fNIRS) to non-invasively measure hemoglobin …

Near-infrared spectroscopy (NIRS) enables continuous non-invasive quantification of blood
and tissue oxygenation, and may be useful for quantification of cerebral blood volume (CBV) …

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 used near infrared spectroscopy (NIRS) to investigate the vascular and metabolic
response to brain activation in human primary and adjacent secondary visual cortex. NIRS is …
