Brain Decoding Using fNIRS

Proceedings of the AAAI Conference on Artificial Intelligence, 2021
Brain activation can reflect semantic information elicited by natural words and concepts. Increasing research has been conducted on decoding such neural activation patterns using representational semantic models. However, prior work decoding semantic meaning from neurophysiological responses has been largely limited to ECoG, fMRI, MEG, and EEG ...

fNIRS measurements in migraine

SPIE Proceedings, 2005
Migraine is a complex chronic neurovascular disorder in which the interictal changes in neuronal excitability and vascular reactivity in the cerebral cortex were detected. The extent and direction of the changes in cerebral blood flow that affect cerebral hemodynamics during attacks, however, are still a matter of debate. This may have been due to

A Wearable Wireless fNIRS System

Proceedings of the 2018 8th International Conference on Bioscience, Biochemistry and Bioinformatics, 2018
Neurovascular coupling mechanisms in functional brain activity has always been important areas of brain science. Functional near-infrared spectroscopy (fNIRS) has been utilized in the recent decades for examining functional brain activity by measuring the changes in the concentrations of oxygenated and deoxygenated hemoglobin.

Statistical analysis of fNIRS data: A comprehensive review

open access: yesNeuroImage, 2014
Functional near-infrared spectroscopy (fNIRS) is a non-invasive method to measure brain activities using the changes of optical absorption in the brain through the intact skull. fNIRS has many advantages over other neuroimaging modalities such as positron emission tomography (PET), functional magnetic resonance imaging (fMRI), or magnetoencephalography

Is EEG causal to fNIRs?

2016 IEEE International Conference on Bioinformatics and Biomedicine (BIBM), 2016
Causality analysis of simultaneous measurements of the brain's electrical activity and its hemodynamic activity provides the opportunity to study the neural underpinning of hemodynamic fluctuations. This multimodal analysis can also be used to extract valuable information regarding the location of the generators of various electrical events such as ...

Translating fMRI to fNIRS

2013 6th International IEEE/EMBS Conference on Neural Engineering (NER), 2013
Blood oxygenation level dependent (BOLD) functional magnetic resonance (fMRI) imaging and functional near infrared spectroscopy (fNIRS) have been widely used to investigate hemodynamic responses to functional stimulation in the human brain. In the present study, we propose a time dependent multi layered Monte Carlo (TD-MCML) simulation approach for ...

Assessment of mental workload by EEG+FNIRS

2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016
We investigated the use of a multimodal functional neuroimaging system in quantifying mental workload of healthy human volunteers. We recorded behavioral performance measures as well as electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS) simultaneously from subjects performing n-back tasks. The EEG and fNIRS signals were used
