Abstract | Near-infrared spectroscopy (NIRS) has been largely used in neuroscience as an alternative non-invasive neuroimaging technique, primarily to measure the oxygenation levels of cerebral haemoglobin. Its portability and relative robustness against motion artefacts made it an ideal method to measure cerebral blood changes during physical activity. Usually referred to as ’functional’ NIRS (fNIRS) when used to monitor brain changes during motor or cognitive tasks, this technique often involves the montage the probes on the forehead of the participants to gauge the neurophysiological underpinning of executive functioning. Other applications of NIRS include other aspects of cerebral hemodynamics such as cerebral pulsatility. However, there is an important aspect that fNIRS studies do not seem to have taken into account so far, which relates to the capacity of near-infrared light to modulate cognitive and psychological processes according to what is known as photobiomodulation (PBM). Hence, drawing on a selection of NIRS and PBM experiments, we argue in favour of an integrative view for NIR-based neuroimaging studies, which should embrace a control for the possible effects of light stimulation, especially when fNIRS is considered to test the effect of an intervention. |
