Near-infrared spectroscopy (NIRS) is a noninvasive technique for continuous monitoring of
the amounts of total hemoglobin (total-Hb), oxygenated hemoglobin,(oxy-Hb) and …

Brain activity is associated with changes in optical properties of brain tissue. Optical
measurements during brain activation can assess haemoglobin oxygenation, cytochrome-c …

The purpose of the this article is to describe an emerging neuroimaging technology,
functional near-infrared spectroscopy (fNIRs), which has several attributes that make it …

Functional near-infrared spectroscopy (fNIRS) is an emerging functional neuroimaging
technology offering a relatively non-invasive, safe, portable, and low-cost method of indirect …

Near infrared spectroscopy (NIRS) can detect changes in the concentrations of oxy-
hemoglobin ([HbO]) and deoxy-hemoglobin ([Hb]) in tissue based upon differential …

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 …

This paper gives an overview of principles, technologies, and applications using near
infrared spectrometry and imaging (NIRS and NIRI) to study brain function. The physical …

Previous modeling of near-infrared (NIR) light distribution in models of the adult head
incorporating a clear nonscattering cerebrospinal fluid (CSF) layer have shown the latter to …

Functional near-infrared spectroscopy (fNIRS) is an optical diffusion technique that allows
the non-invasive imaging of cortical activity. During the last two decades, rapid technical and …
