Abstract The past few decades have seen a rapid increase in the use of functional near‐infrared spectroscopy (fNIRS) cognitive neuroscience. This fast growth is due to several advances that fNIRS offers over other neuroimaging modalities such as magnetic resonance imaging and electroencephalography/magnetoencephalography. In particular, harmless, tolerant bodily movements, highly portable, being suitable for all possible participant populations, from newborns elderly experimental settings, both inside outside laboratory. this review we aim provide comprehensive state‐of‐the‐art basics, technical developments, applications. discuss some open challenges potential neuroscience research, with particular focus on naturalistic environments social

False positives and false negatives in functional near-infrared spectroscopy: issues, challenges, and the way forward

Neurophotonics, Journal Year: 2016, Volume and Issue: 3(3), P. 031405 - 031405

Published: March 9, 2016

We highlight a significant problem that needs to be considered and addressed when performing functional near-infrared spectroscopy (fNIRS) studies, namely the possibility of inadvertently measuring fNIRS hemodynamic responses are not due neurovascular coupling. These can misinterpreted as brain activity, i.e., “false positives” (errors caused by wrongly assigning detected response activity), or mask negatives” observed in presence activity). Here, we summarize possible physiological origins these issues suggest ways avoid remove them.

For cognitive processes to function well, it is essential that the brain optimally supplied with oxygen and blood. In recent years, evidence has emerged suggesting cerebral oxygenation hemodynamics can be modified physical activity. To better understand relationship between oxygenation/hemodynamics, activity, cognition, application of state-of-the art neuroimaging tools essential. Functional near-infrared spectroscopy (fNIRS) such a tool especially suitable investigate effects activity/exercises on due its capability quantify changes in concentration oxygenated hemoglobin (oxyHb) deoxygenated (deoxyHb) non-invasively human brain. However, currently there no clear standardized procedure regarding application, data processing, analysis fNIRS, large heterogeneity how fNIRS applied field exercise–cognition science. Therefore, this review aims summarize current methodological knowledge about studies measuring cortical hemodynamic responses during testing (i) prior after different activities interventions, (ii) cross-sectional accounting for fitness level their participants.

Functional near-infrared spectroscopy (fNIRS) research articles show a large heterogeneity in the analysis approaches and pre-processing procedures. Additionally, there is often lack of complete description methods applied, necessary for study replication or results comparison. The aims this paper were (i) to review investigate which information generally included published fNIRS papers, (ii) define signal procedure set common ground standardization guidelines. To goal, we have reviewed 110 2016 field cognitive neuroscience, performed simulation with synthetic data optimize filtering step before applying GLM method statistical inference. Our highlight fact that many papers important information, variability used. simulations demonstrated optimal approach remove noise recover hemodynamic response from framework use 1000th order band-pass Finite Impulse Response filter.

Organizational Research Methods, Journal Year: 2016, Volume and Issue: 22(1), P. 46 - 68

Published: July 18, 2016

Upon adequate stimulation, real-time maps of cortical hemodynamic responses can be obtained by functional near-infrared spectroscopy (fNIRS), which noninvasively measures changes in oxygenated and deoxygenated hemoglobin after positioning multiple sources detectors over the human scalp. This review is aimed at giving a concise simple overview basic principles fNIRS including features, strengths, advantages, limitations, utility for evaluating behavior. The transportable/wireless commercially available systems have time resolution 1 to 10 Hz, depth sensitivity about 1.5 cm, spatial up cm. has been found suitable many applications on beings, either adults or infants/children, field social sciences, neuroimaging research, medicine. Some examples present future prospects assessing cerebral cortex function during behavior different situations (in natural situations) will provided. Moreover, most recent studies investigating interpersonal interactions adopting hyperscanning approach, consists measurement brain activity simultaneously two more people, reported.
