For cognitive processes to function well, it is essential that the brain is optimally supplied
with oxygen and blood. In recent years, evidence has emerged suggesting that cerebral …

This year marks the 20th anniversary of functional near-infrared spectroscopy and imaging
(fNIRS/fNIRI). As the vast majority of commercial instruments developed until now are based …

Summary Ultra-slow,∼ 0.1-Hz variations in the oxygenation level of brain blood are widely
used as an fMRI-based surrogate of “resting-state” neuronal activity. The temporal …

The goal of resting-state functional magnetic resonance imaging (fMRI) is to investigate the
brain's functional connections by using the temporal similarity between blood oxygenation …

Resting-state signals in blood-oxygenation-level-dependent (BOLD) imaging are used to
parcellate brain regions and define “functional connections” between regions. Yet a …

Near-infrared spectroscopy (NIRS) is a noninvasive neuroimaging tool for studying evoked
hemodynamic changes within the brain. By this technique, changes in the optical absorption …

The majority of functional neuroscience studies have focused on the brain's response to a
task or stimulus. However, the brain is very active even in the absence of explicit input or …

Functional near infrared spectroscopy (fNIRS) is a versatile neuroimaging tool with an
increasing acceptance in the neuroimaging community. While often lauded for its portability …

Functional MRI (fMRI) can be applied to study the functional connectivity of the human brain.
It has been suggested that fluctuations in the blood oxygenation level-dependent (BOLD) …

Inferring resting-state connectivity patterns from functional magnetic resonance imaging
(fMRI) data is a challenging task for any analytical technique. In this paper, we review a …
