Optimal hemodynamic response model for functional near-infrared spectroscopy

open access: yesFrontiers in Behavioral Neuroscience, 2015
Functional near-infrared spectroscopy (fNIRS) is an emerging non-invasive brain imaging technique and measures brain activities by means of near-infrared light of 650-950 nm wavelengths.

Functional near-infrared spectroscopy for intraoperative brain mapping [PDF]

open access: yesNeurophotonics, 2019
Functional near-infrared spectroscopy (fNIRS) is a relatively new seizure-free technique and its value for intraoperative brain mapping is unknown. We examine the feasibility of fNIRS for intraoperative functional brain mapping. A 1 × 1    cm 2 density fNIRS probe specially designed for intraoperative use was used to map brain function in adult ...

Functional Near Infrared Spectroscopy (fNIRS) synthetic data generation [PDF]

open access: yes2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
Accurately modelled computer-generated data can be used in place of real-world signals for the design, test and validation of signal processing techniques in situations where real data is difficult to obtain. Bio-signal processing researchers interested in working with fNIRS data are restricted due to the lack of freely available fNIRS data and by the ...

Frequency-Domain Techniques for Cerebral and Functional Near-Infrared Spectroscopy

open access: yesFrontiers in Neuroscience, 2020
This article reviews the basic principles of frequency-domain near-infrared spectroscopy (FD-NIRS), which relies on intensity-modulated light sources and phase-sensitive optical detection, and its non-invasive applications to the brain.
