This study aims to assess the posture-related changes in frequency-specific effective connectivity (EC) in elderly subjects by coupling function measured using functional near-infrared spectroscopy (fNIRS). The fNIRS signals were continuously recorded from the bilateral prefrontal cortex (PFC), motor cortex (MC), and occipital lobe (OL) in 17 healthy elderly and 19 healthy young subjects during sitting and standing states. EC was calculated based on Dynamic Bayesian inference in one low…

A Systematic Review of the Application of Functional Near-Infrared Spectroscopy to the Study of Cerebral Hemodynamics in Healthy Aging
TLDR
An age-related reduction in resting-state cerebral oxygenation and connectivity in the prefrontal cortex is revealed, and the beneficial effects of healthy lifestyles and the detrimental effects of cardiovascular disease risk factors on brain functioning among nondemented older adults are described.
Differences in Net Information Flow and Dynamic Connectivity Metrics Between Physically Active and Inactive Subjects Measured by Functional Near-Infrared Spectroscopy (fNIRS) During a Fatiguing Handgrip Task
TLDR
The findings imply that physical activity modulates neurovascular control mechanisms at the endogenic, neurogenic, and myogenic frequency bands resulting in delayed fatigue onset and enhanced performance.
Effects of three different rehabilitation games' interaction on brain activation using functional near-infrared spectroscopy.
TLDR
The results show that the brain regions responded more strongly when activated by the physical and motion-sensing states compared with the button-push training state, and the physicaland motion-Sensing states are more conducive to the rehabilitation of the nervous system.
Monitoring Neural Activity during Motion-Force Control Task Using Functional Near-Infrared Spectroscopy
TLDR
This study indicates the sensitivity of using fNirS to differentiate difficulty levels in haptic tasks, and supports the potential of fNIRS in realistic haptic interaction.
Differences in directed functional brain connectivity related to age and sex
TLDR
The findings support the use of DGM as a measure of directed connectivity in rsfMRI data and provide new insight into the shaping of the connectome during aging.
Differences in directed functional brain connectivity related to age, sex and mental health
TLDR
The findings support the use of DGM as a measure of directed connectivity in rsfMRI data and provide new insight into the shaping of the connectome during aging.
Sensory manipulation results in increased dorsolateral prefrontal cortex activation during static postural balance in sedentary older adults: An fNIRS study
TLDR
The effects of aging on the DLPFC when sensory cues were removed or presented inaccurately during the sensory orientation test (SOT) are understood.
Relevance of Emotional Conflict and Gender Differences in the Cognitive Tasks of Digital Interface Layouts Using NIRS Technology
TLDR
The results showed that there is a gender difference in cognition of the interface layout with combinations of 3 and 4 layout elements in the behavioral experiment and behavioral response was positively correlated with brain function.

Functional connectivity analysis of distracted drivers based on the wavelet phase coherence of functional near-infrared spectroscopy signals
TLDR
The results suggest that the changed FC levels in intervals IV, V, and VI were more likely to reflect the driver’s distraction condition, and the method may be used for the evaluation of drivers’ attention level.

Spectral analysis of near-infrared spectroscopy signals measured from prefrontal lobe in subjects at risk for stroke.
TLDR
The reduction of spontaneous oscillations in subjects at risk for stroke suggests an increased stiffness in the cerebral artery and indicates the possibility of applying spontaneously oscillations, based on the wavelet transform of NIRS signals, to assess the risk in subjects with atherosclerosis.
