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 …

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

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 …

This mini-review is aimed at briefly summarizing the present status of functional near-
infrared spectroscopy (fNIRS) and predicting where the technique should go in the next …

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 spectroscopy (NIRS) can detect vascular changes in cerebral cortical tissue
elicited by functional stimulation. For some 10 years, another optical signal has been …

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

This review celebrates the 30th anniversary of the first in vivo near-infrared (NIR)
spectroscopy (NIRS) publication, which was authored by Professor Frans Jöbsis. At first …

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 …

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 …
