Significance: Time-domain functional near-infrared spectroscopy (TD-fNIRS) has been
considered as the gold standard of noninvasive optical brain imaging devices. However …

We present a lightweight TD-NIRS system, two-wavelength, one detection channel that can
be battery operated and worn as a backpack for freely-moving cerebral and muscle …

Even though research in the field of functional near-infrared spectroscopy (fNIRS) has been
performed for more than 20 years, consensus on signal processing methods is still lacking …

Functional near-infrared spectroscopy (fNIRS) allows the ability to monitor brain activation
by measuring changes in the concentration of oxy-and deoxy-hemoglobin. Until now no …

Similar to functional magnetic resonance imaging (fMRI), functional near-infrared
spectroscopy (fNIRS) detects the changes of hemoglobin species inside the brain, but via …

This review is aimed at presenting the state-of-the-art of time domain (TD) functional near-
infrared spectroscopy (fNIRS). We first introduce the physical principles, the basics of …

We report development, testing, and in vivo characterization of a multichannel optical probe
for continuous wave (CW) functional near-infrared spectroscopy (fNIRS) that relies on silicon …

Abstract Background Application of functional Near InfraRed Spectroscopy (fNIRS) in
neurology is still limited as a good optical coupling and optimized optode coverage of …

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 …

We present a description of evolution of time-resolved systems developed at the Department
of Physics, Politecnico di Milano for tissue oximetry and functional brain imaging. From a …
