Effective Connectivity Analysis of the Brain Network in Drivers during Actual Driving Using Near-Infrared Spectroscopy
Findings indicate that the hemodynamic activity level of the cerebral cortex increases linearly with increasing cognitive workload, which can be strengthened by a Cognitive workload, but also can be weakened by a superfluous cognitive workload.
Functional connectivity analysis of distracted drivers based on the wavelet phase coherence of functional near-infrared spectroscopy signals
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.
Alteration in Brain Functional and Effective Connectivity in Subjects With Hypertension
Low WPCO and CS indicated a reduced network interaction, suggesting disturbed neurovascular coupling in subjects with hypertension, which may provide evidence of impaired cognitive function in hypertension and can enhance the understanding on neurov vascular coupling.
Frequency‐specific functional connectivity related to the rehabilitation task of stroke patients
Analysis of the brain network patterns of stroke patients while performing a four-limb linkage rehabilitation training using the functional near-infrared spectroscopy (fNIRS) method suggested that the frequency-specific FC methods based on WPCO would provide a potential approach to quantitatively assess the effect of rehabilitation tasks.
Limb linkage rehabilitation training-related changes in cortical activation and effective connectivity after stroke: A functional near-infrared spectroscopy study
The results showed that the stroke patients exhibited an asymmetric (greater activation in the contralesional versus ipsilesional motor region) cortical activation pattern versus healthy controls, which suggested that plastic reorganization of cognitive resources severed to compensate for impairment in stroke patients during the motor rehabilitation task.
Alterations in the coupling functions between cerebral oxyhaemoglobin and arterial blood pressure signals in post-stroke subjects
No significant difference in region-wise CS between affected and unaffected sides was observed in stroke groups, indicating an evidence of globally impaired CA.

The decreased effective connectivity levels among brain regions may be a marker of impaired cognitive function in the mild cognitive impairment group.

Findings suggested that TCC training improved the connection of PFC, MC and OC in myogenic activity, sympathetic nervous system, and endothelial cell metabolic activities; enhanced brain functional connections and relayed the ability of TCC to improve cognition and the anti–memory decline potential.
Effective Connectivity in Response to Posture Changes in Elderly Subjects as Assessed Using Functional Near-Infrared Spectroscopy
Results revealed the age-related changes in reorganization of interregional interactions for different postures in elderly subjects as compared with that in the young group and may provide evidence of impaired cognitive function in the elderly.
