The letter-fluency task-induced response over the prefrontal cortex is investigated bilaterally on eight subjects using a recently developed compact, eight-channel, time-resolved, near-IR system. The cross-subject mean values of prefrontal cortex oxygen saturation (SO2) were 68.8+/-3.2% (right) and 71.0+/-3.6% (left), and of total hemoglobin concentration (tHb) were 69.6+/-9.6 microM (right) and 69.5+/-9.9 microM (left). The typical cortical activation response to the cognitive task…

Relation between working memory performance and evoked cerebral blood oxygenation changes in the prefrontal cortex evaluated by quantitative time-resolved near-infrared spectroscopy

Qualitative, near-infrared time-resolved spectroscopy is compact and less expensive than functional magnetic resonance imaging, and may be a useful tool to evaluate neural correlates of WM in normal adults.

Frontal cerebral oxygenation asymmetry: intersubject variability and dependence on systemic physiology, season, and time of day

It is shown that frontal cerebral oxygenation asymmetry (FCOA) is a real phenomenon in healthy human subjects at rest and SSPA-fNIRS provides unique insights into this remarkable phenomenon.

Individual Differences in Hemodynamic Responses Measured on the Head Due to a Long-Term Stimulation Involving Colored Light Exposure and a Cognitive Task: A SPA-fNIRS Study

There is substantial intersubject-variability of cerebral hemodynamic responses, which is partially explained by subject-specific systemic physiological changes induced by the CLE-VFT, which means that both subgroup analyses and the additional assessment of systemic physiology are of crucial importance to achieve a comprehensive understanding of the effects of a CLE- VFT on human subjects.

Load-dependent brain activation assessed by time-domain functional near-infrared spectroscopy during a working memory task with graded levels of difficulty.

The present work successfully explored the capability of fNIRS to detect the two neurophysiological categories under investigation and distinguish their activation patterns, using time-domain functional near-infrared spectroscopy.

Color-dependent changes in humans during a verbal fluency task under colored light exposure assessed by SPA-fNIRS

It is shown that the CLE has effects that endure at least 15 min after cessation of the CLE, which underlines the importance of considering the persistent influence of colored light on brain function, cognition, and systemic physiology in everyday life.

Prefrontal Cerebral Oxygenated Hemoglobin Concentration during the Category Fluency and Finger-Tapping Tasks in Adults with and without Mild Cognitive Impairment: A Near-Infrared Spectroscopy Study

The cerebral oxyhemoglobin signal trended toward the highest values during the category fluency task in young participants and during the finger-tapping task in elderly participants regardless of the MCI status, indicating a low discrimination ability between elderly participants with and without MCI.



Frontal brain activation during the Wisconsin Card Sorting Test assessed with two-channel near-infrared spectroscopy

A significant bilateral increase of O2HB in frontal brain regions without hemispheric differences was found during the Wisconsin Card Sorting Test compared with a baseline at rest, indicating an enhanced perfusion of the frontal lobes consistent with local activation.
