Frontal and motor cortex oxygenation during maximal exercise in normoxia and hypoxia.
Reductions in prefrontal oxygenation near maximal exertion may limit exercise performance by impairing executive functions that influence the decision to stop exercising; however, whether deoxygenation also occurs in motor regions that more directly affect central motor drive is unknown. Multichannel near-infrared spectroscopy was used to compare changes in prefrontal, premotor, and motor corti...
متن کاملPrefrontal Activation during Emotional Experience as Measured by Nirs
To investigate brain activation in the prefrontal cortex (PFC) during emotional experiences, we examined blood oxygenation changes of healthy female volunteers by using multi-channel Near Infrared Spectroscopy (NIRS). Results directly confirmed that the PFC was activated during emotional tasks suggesting that the levels of oxy-Hb increased significantly larger in negative periods compared with ...
متن کاملPrefrontal cortex oxygenation during incremental exercise in chronic fatigue syndrome.
This study examined the effects of maximal incremental exercise on cerebral oxygenation in chronic fatigue syndrome (CFS) subjects. Furthermore, we tested the hypothesis that CFS subjects have a reduced oxygen delivery to the brain during exercise. Six female CFS and eight control (CON) subjects (similar in height, weight, body mass index and physical activity level) performed an incremental cy...
متن کاملNIRS-measured prefrontal cortex activity in neuroergonomics: strengths and weaknesses
INTRODUCTION Contemporary daily life is more and more characterized by ubiquitous interaction with computational devices and systems. For example, it is commonplace for a person walking a busy street, to be engaged in conversation with a distant person using telephony, while simultaneously receiving directions via a GPS-enabled web application on their mobile device. This overwhelming increase ...
متن کاملChanges in skeletal muscle oxygenation during exercise measured by near-infrared spectroscopy on ascent to altitude
INTRODUCTION We sought to quantify changes in skeletal muscle oxygenation during exercise using near-infrared spectroscopy (NIRS) in healthy volunteers ascending to high altitude. METHODS Using NIRS, skeletal muscle tissue oxygen saturation (StO2) was measured in the vastus lateralis of 24 subjects. Measurements were performed at sea level (SL; 75 m), at 3,500 m, on arrival at 5,300 m (5,300 ...
