Identification of the cognitive interference effect related to stroop stimulation: Using dynamic causal modeling of effective connectivity in functional near-infrared spectroscopy (fnirs)

Background: The Stroop test is a well-known model to denote the decline in performance under the incongruent condition, which requires selective attention and control of competitive responses. Functional near-infrared spectroscopy can identify …

Aging effects on prefrontal cortex oxygenation in a posture-cognition dual-task: an fNIRS pilot study

Background: The aging process alters upright posture and locomotion control from an automatically processed to a more cortically controlled one. The present study investigated a postural-cognitive dual-task paradigm in young and older adults using …

Associations of class-time sitting, stepping and sit-to-stand transitions with cognitive functions and brain activity in children

Previous research showed that children's physical activity is positively related to executive functions, whilst screen time shows negative associations. However, it is unclear how school-based sitting time and transitions from sitting to standing …

Flow experience and the mobilization of attentional resources

The present study attempts to better identify the neurophysiological changes occurring during flow experience and how this can be related to the mobilization of attentional resources. Self-reports of flow (using a flow feelings scale) and attention …

Vigilance task-related change in brain functional connectivity as revealed by wavelet phase coherence analysis of near-infrared spectroscopy signals

This study aims to assess the vigilance task-related change in connectivity in healthy adults using wavelet phase coherence (WPCO) analysis of near-infrared spectroscopy signals (NIRS). NIRS is a non-invasive neuroimaging technique for assessing …
