Investigation of frontal lobe activation with fNIRS and systemic changes during video gaming

Frontal lobe activation caused by tasks such as videogames can be investigated using multichannel near-infrared spectroscopy (fNIRS), sometimes called optical topography. The aims of this study are to investigate the effects of video gaming (fighting …

NIRS measurements with elite speed skaters: Comparison between the ice rink and the laboratory

Wearable, wireless near-infrared (NIR) spectrometers were used to compare changes in on-ice short-track skating race simulations over 1,500 m with a 3-min cycle ergometry test at constant power output (400 W). The subjects were six male elite …

Saturation of hemoglobin in intracranial arteries is similar in patients with hemodynamically relevant and irrelevant stenosis of the internal carotid artery

The aim of this study was to establish if patients with hemodynamically relevant or irrelevant stenoses of the extracranial internal carotid artery have different intracranial arterial oxygen saturation as measured by transcranial pulse oximetry …

New methods for monitoring cerebral oxygenation and hemodynamics in patients with subarachnoid hemorrhage

Radiographic cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH) do not reflect cerebral hemodynamics and oxygenation and may occur in the absence of clinical deficit and vice-versa. This report is to describe preliminary findings in further …
