NICA: A Novel Toolbox for Near-Infrared Spectroscopy Calculations and Analyses

Frontiers in Neuroinformatics, 2020
Functional near-infrared spectroscopy (fNIRS) measures the functional activity of the cerebral cortex. The concentration changes of oxygenated (oxy-Hb) and deoxygenated hemoglobin (deoxy-Hb) can be detected and associated with activation of the cortex in

Assessment of cerebrovascular dysfunction after traumatic brain injury with fMRI and fNIRS

NeuroImage: Clinical, 2020
Traumatic cerebral vascular injury (TCVI) is a frequent, but under-recognized, endophenotype of traumatic brain injury (TBI).  It likely contributes to functional deficits after TBI and TBI-related chronic disability, and represents an attractive target ...

Functional near-infrared spectroscopy in the neuropsychological assessment of spatial memory: A systematic review

Acta Psychologica, 2022
Functional near-infrared spectroscopy (fNIRS) is a non-invasive optical imaging technique that employs near-infrared light to measure cortical brain oxygenation. The use of fNIRS has increased exponentially in recent years.

fNIRS for future use in auditory diagnostics

Current Directions in Biomedical Engineering, 2016
Functional near-infrared spectroscopy (fNIRS) is an emerging technique for the assessment of functional activity of the cerebral cortex. Recently fNIRS was also envisaged as a novel neuroimaging approach for measuring the auditory cortex (AC) activity in

Event-related functional near-infrared spectroscopy (fNIRS): Are the measurements reliable?

NeuroImage, 2006
The purpose of the present study was to investigate the retest reliability of event-related functional near-infrared spectroscopy (fNIRS). Therefore, isolated functional activation was evoked in the occipital cortex by a periodic checkerboard stimulation.

Cortical correlates of speech intelligibility measured using functional near-infrared spectroscopy (fNIRS) [PDF]

Hearing Research, 2018
Functional neuroimaging has identified that the temporal, frontal and parietal cortex support core aspects of speech processing. An objective measure of speech intelligibility based on cortical activation in these brain regions would be extremely useful to speech communication and hearing device applications. In the current study, we used noise-vocoded

Functional Near-Infrared Spectroscopy (fNIRS): Principles and Neuroscientific Applications

, 2012
fNIRS is a device designed to detect changes in the concentration of oxygenated (oxyHb) and deoxygenated (deoxyHb) haemoglobin molecules in the blood, a method commonly used to assess cerebral activity. Over the last decade, functional near-infrared spectroscopy (fNIRS) has widely extended its applications due to its capacity to quantify oxygenation in

Disentangling the effects of near-infrared light stimulation and exercise on cognitive function in fNIRS studies

NeuroImage
Functional near-infrared spectroscopy (fNIRS) studies often aim to measure changes in the brain's hemodynamic response in relation to a specific intervention.

How Stress Affects Functional Near-Infrared Spectroscopy (fNIRS) Measurements of Mental Workload [PDF]

Extended Abstracts of the 2018 CHI Conference on Human Factors in Computing Systems, 2018
Recent work has demonstrated that functional Near-Infrared Spectroscopy has the potential to measure changes in Mental Workload with increasing ecological validity. It is not clear, however, whether these measurements are affected by anxiety and stress of the workload, where our informal observations see some participants enjoying the workload and ...
