Enhancing fNIRS Analysis Using EEG Rhythmic Signatures: An EEG-Informed fNIRS Analysis Study
IEEE Transactions on Biomedical Engineering, 2020Neurovascular coupling represents the relationship between changes in neuronal activity and cerebral hemodynamics. Concurrent Electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS) recording and integration analysis has emerged as a promising multi-modal neuroimaging approach to study the neurovascular coupling as it provides ...

fNIRS-based online deception decoding
Journal of Neural Engineering, 2012Deception involves complex neural processes in the brain. Different techniques have been used to study and understand brain mechanisms during deception. Moreover, efforts have been made to develop schemes that can detect and differentiate deception and truth-telling.

Social hyperscanning with fNIRS
Gesture, 2020Abstract The interest of neuroscience has been aimed at the investigation of the neural bases underlying gestural communication. This research explored the intra- and inter-brain connectivity between encoder and decoder. Specifically, adopting a “hyperscanning paradigm” with the functional Near-infrared Spectroscopy (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 ...

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 ...

Near-infrared spectroscopy (NIRS) was originally designed for clinical monitoring of tissue oxygenation, and it has also been developed into a useful tool in neuroimaging studies, with the so-called functional NIRS (fNIRS). With NIRS, cerebral activation is detected by measuring the cerebral hemoglobin (Hb), where however, the precise correlation ...

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 ...

Assessment of mental workload by EEG+FNIRS
2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016We 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

Mental stress grading based on fNIRS signals
2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016In this study, we propose functional near infrared spectroscopy (fNIRS) to objectively grade different levels of mental stress. The levels of stress were set based on the difficulty of arithmetic task, time pressure and negative feedback about peer performance. We examined the proposed approach on twelve human subjects using the Montreal Imaging Stress

Cognitive Performance Assessment Using fNIR
Archives of Physical Medicine and Rehabilitation, 2019First, the present study investigated the relationship between cognitive demand and two performance measures that measure outcome and response time. Second, it investigated the utility of functional Near InfraRed Spectroscopy (fNIR) a brain imaging device to measure the hemodynamic response in the prefrontal cortex during the performance measures as a ...
