Functional near-infrared spectroscopy

IEEE Engineering in Medicine and Biology Magazine, 2006
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 possible to conduct neuroimaging studies of the cortex in clinical offices and under more realistic, ecologically valid parameters.

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 ...

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,

Applications of functional near-infrared spectroscopy (fNIRS) in neonates

Neuroscience Research, 2021
Functional near-infrared spectroscopy (fNIRS) is a method of monitoring brain oxygenation. This technique investigates hemodynamic changes in the cerebral cortex. fNIRS is widely used in clinical and scientific research. In this review, we focus on the applications of fNIRS on neonates.

Diagnosis of Mild Cognitive Impairment Using Cognitive Tasks: A Functional Near-Infrared Spectroscopy Study.

Current Alzheimer Research, 2021
BACKGROUND Early diagnosis of Alzheimer's disease (AD) is essential to prevent its progression to dementia. Mild cognitive impairment (MCI) can be indicative of early-stage AD.

Cerebrovascular Reactivity Measurement with Functional Near Infrared Spectroscopy

Journal of Visualized Experiments, 2022
Cerebrovascular reactivity (CVR) is the capacity of blood vessels in the brain to alter cerebral blood flow (either with dilation or constriction) in response to chemical or physical stimuli. The amount of reactivity in the cerebral microvasculature depends on the integrity of the capacitance vasculature and is the primary function of endothelial cells.

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 ...

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.

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.
