Brain activation for alertness measured with functional near infrared spectroscopy (fNIRS)

Psychophysiology, 2008
AbstractAlertness is a basic psychological function within the construct of attention. The neural basis of alertness has been found in the right frontotemporal cortex and the left ventrolateral prefrontal cortex. The aim of the present study was to establish the measurement of functional brain activity during alertness with functional near infrared ...

Auditory cortex activation is modulated by emotion: A functional near-infrared spectroscopy (fNIRS) study

NeuroImage, 2011
Visual emotional stimuli evoke enhanced activation in early visual cortex areas which may help organisms to quickly detect biologically salient cues and initiate appropriate approach or avoidance behavior. Functional neuroimaging evidence for the modulation of other sensory modalities by emotion is scarce. Therefore, the aim of the present study was to

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 ...

Assessing Driver Frustration Using Functional Near-Infrared Spectroscopy (fNIRS)

2018
Introduction and Aim: Driving is a goal-directed task. During traffic, blocking obstacles occur often eliciting driver frustration, and may result in more risky driving including speeding and aggressive behavior towards other traffic road participants.

Is Functional Near Infrared Spectroscopy (fNIRS) Appropriate for your Research?

Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2016
Functional near infrared spectroscopy (fNIRS) is an emerging neuroimaging technique that has found home in various human factors and ergonomics applications. Why fNIRS? Is it better than EEG or fMRI? Is it an appropriate neuroimaging technique for my research/application? What are the methodological considerations for fNIRS analyses?

The contribution of functional near-infrared spectroscopy (fNIRS) to the presurgical assessment of language function in children

Brain and Language, 2012
Before performing neurosurgery, an exhaustive presurgical assessment is required, usually including an investigation of language cerebral lateralization. Among the available procedures, the intracarotid amobarbital test (IAT) was formerly the most widely used.

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

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

Independent Component Analysis of Event-related Functional Near-infrared Spectroscopy (fNIRS)

2008 International Conference on BioMedical Engineering and Informatics, 2008
Functional near-infrared spectroscopy (fNIRS) is a non-invasive method for studying functional activation via monitoring changes of the hemodynamic properties in brain and event-related experimental in examining cognitive processes is very useful but much more flexible in data analysis. To validate the usefulness of independent component analysis (ICA)

Neuroimaging and cognition using functional near infrared spectroscopy (fNIRS) in multiple sclerosis

Brain Imaging and Behavior, 2014
The present study utilized functional near infrared spectroscopy (fNIRS) to detect neural activation differences in the orbitofrontal brain region between individuals with multiple sclerosis (MS) and healthy controls (HCs) during a working memory (WM) task. Thirteen individuals with MS and 12 HCs underwent fNIRS recording while performing the n-back WM

Functional Near Infrared Spectroscopy System Validation for Simultaneous EEG-FNIRS Measurements

2019
Functional near-infrared spectroscopy (fNIRS) applied to brain monitoring has been gaining increasing relevance in the last years due to its not invasive nature and the capability to work in combination with other well–known techniques such as the EEG. The possible use cases span from neural-rehabilitation to early diagnosis of some neural diseases. In
