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 …

▪ Abstract Interrogation of tissue with light offers the potential for noninvasive chemical
measurement, and penetration with near-infrared wavelengths (750–1000 nm) is greater …

In this Outlook paper, we explain why an accurate physiological interpretation of functional
near-infrared spectroscopy (fNIRS) neuroimaging signals is facilitated when systemic …

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 …

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 …

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 …

Cognitive neuroscience is a multidisciplinary field focused on the exploration of the neural
substrates underlying cognitive functions; the most remarkable progress in understanding …

Near-infrared spectroscopy is discussed from the viewpoint of human higher-order brain
function analysis. Pioneering work in this field is reviewed; then we describe our concept of …

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

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 …
