Although near‐infrared spectroscopy (NIRS) was developed as a tool for clinical monitoring
of tissue oxygenation, it also has potential for neuroimaging. A wide range of different NIRS …

Near-infrared spectroscopy (NIRS), which was originally designed for clinical monitoring of
tissue oxygenation, has been developing into a useful tool for neuroimaging studies …

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

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

Near-infrared (IR) light easily penetrates biological tissue, and the information offered by in
vivo spectroscopy of cerebral oxygenation is detailed and comes with a high temporal …

Changes in cerebral blood flow (CBF) and cerebral metabolic rates (CMRO2) have been
used as indices for changes in neuronal activity. Near–infrared spectroscopy (NIRS) can …

1. Introduction fNIRS is a device designed to detect changes in the concentration of
oxygenated (oxyHb) and deoxygenated (deoxyHb) haemoglobin molecules in the blood, a …

This review is aimed at celebrating the upcoming 20th anniversary of the birth of human
functional near-infrared spectroscopy (fNIRS). After the discovery in 1992 that the functional …

Near-Infrared Spectroscopy (NIRS) and diffuse optical imaging (DOI) are increasingly used
to detect hemodynamic changes in the cerebral cortex induced by brain activity. Until …

Optical approaches to investigate cerebral function and metabolism have long been applied
in invasive studies. From the neuron cultured in vitro to the exposed cortex in the human …
