Mocarts: a lightweight radiation transport simulator for easy handling of complex sensing geometries [PDF]

open access: yes, 2016
In functional neuroimaging (fNIRS), elaborated sensing geometries pairing multiple light sources and detectors arranged over the tissue surface are needed. A variety of software tools for probing forward models of radiation transport in tissue exist, but

False positives and false negatives in functional near-infrared spectroscopy: issues, challenges, and the way forward [PDF]

open access: yes, 2016
We highlight a significant problem that needs to be considered and addressed when performing functional near-infrared spectroscopy (fNIRS) studies, namely the possibility of inadvertently measuring fNIRS hemodynamic responses that are not due to ...

fNIRS for future use in auditory diagnostics

open access: yesCurrent 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

Epigenetic modification of the oxytocin receptor gene is associated with emotion processing in the infant brain [PDF]

open access: yes, 2019
The neural capacity to discriminate between emotions emerges early in development, though little is known about specific factors that contribute to variability in this vital skill during infancy.

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

open access: yes, 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

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

Optics Based Label-Free Techniques and Applications in Brain Monitoring

open access: yesApplied Sciences, 2020
Functional near-infrared spectroscopy (fNIRS) has been utilized already around three decades for monitoring the brain, in particular, oxygenation changes in the cerebral cortex.

fNIRS response during walking — Artefact or cortical activity? A systematic review [PDF]

open access: yes, 2017
This systematic review aims to (i) evaluate functional near infrared spectroscopy (fNIRS) walking study design in young adults, older adults and people with Parkinson’s disease (PD); (ii) examine signal processing techniques to reduce artefacts and ...

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

open access: yesExtended 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 ...

Effects of aging on cerebral oxygenation during working-memory performance: A functional near-infrared spectroscopy study [PDF]

open access: yes, 2000
Contains fulltext : 102484.pdf (publisher's version ) (Open Access)Working memory is sensitive to aging-related decline. Evidence exists that aging is accompanied by a reorganization of the working-memory circuitry, but the underlying ...
