Superficial Fluctuations in Functional Near-Infrared Spectroscopy

2019 41st Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2019
Functional near-infrared spectroscopy (fNIRS) is a non-invasive optical functional neuroimaging that has seen rapid development and increasing use in studying human brain under normal and diseased conditions. Compared with blood-oxygenation-level dependent functional magnetic resonance imaging (BOLD fMRI), fNIRS offers advantages including its low cost,

Resting state functional near infrared spectroscopy

2013 Pan American Health Care Exchanges (PAHCE), 2013
The present study investigated the spatial-temporal variation of oxygenated hemoglobin (HbO), deoxygenated hemoglobin (Hb), blood volume (BV) and blood oxygenation (BO) concentration changes in the prefrontal cortex, measured with functional near-infrared spectroscopy (fNIRS) during resting state.

Conducting Hyperscanning Experiments with Functional Near-Infrared Spectroscopy

Journal of Visualized Experiments, 2019
Concurrent brain recordings of two or more interacting persons, an approach termed hyperscanning, are gaining increasing importance for our understanding of the neurobiological underpinnings of social interactions, and possibly interpersonal relationships.

Speaking mode recognition from functional Near Infrared Spectroscopy

2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012
Speech is our most natural form of communication and even though functional Near Infrared Spectroscopy (fNIRS) is an increasingly popular modality for Brain Computer Interfaces (BCIs), there are, to the best of our knowledge, no previous studies on speech related tasks in fNIRS-based BCI.

Functional near infrared spectroscopy (fNIRS)

2020
Functional near infrared spectroscopy (fNIRS) provides an essential bridge between our knowledge of adult human brain function and our current understanding of the developing brain. The capacity for fNIRS to provide localized measures of functional activation within awake and mobile infants, combined with a low set-up time and high tolerance to ...

Detecting Concealed Information Using Functional Near-Infrared Spectroscopy

Brain Topography, 2014
The present study focused on the potential application of fNIRS in the detection of concealed information. Participants either committed a mock crime or not and then were presented with a randomized series of probes (crime-related information) and irrelevants (crime-irrelevant information) in a standard concealed information test (CIT). Participants in

Transfer of calibration function in near-infrared spectroscopy

Chemometrics and Intelligent Laboratory Systems, 1995
Abstract A procedure for the transfer of the regression equation in near-infrared spectroscopy (NIRS), from a first instrument to a second instrument, is presented. The procedure uses partial least squares (PLS) regression twice: in the first step to compute the relationship between the spectra of transfer samples of the two instruments, and in the ...

Functional Near-Infrared Spectroscopy

2010
Functional near-infrared spectroscopy (fNIRS) is an emerging optical brain-imaging technology that offers a relatively non-invasive, safe, portable, and low-cost method of both indirect and direct monitoring of brain activity. Most exciting is its potential to allow more ecologically valid investigations that can translate laboratory work into more ...

Near-infrared spectroscopy of hydrocarbon functional groups

Spectrochimica Acta Part A: Molecular Spectroscopy, 1972
Abstract Near-infrared spectra of 50 linear and branched paraffins have been examined in order to improve the knowledge of the behaviour of the bands originated by functional groups, such as methyl and methylene, making up the hydrocarbon molecules.

Functional Near-Infrared Spectroscopy in Cancer Diagnostics

2020
Functional near-infrared spectroscopy (fNIRS) is commonly used in studies of cerebral blood oxygenation and tissue hemodynamics. In recent years, fNIRS has awakened interest also as a potential tool for cancer diagnostics, particularly for breast cancer.
