Abstract

Functional Near-Infrared Spectroscopy (fNIRS) assesses human brain activity by noninvasively measuring changes of cerebral hemoglobin concentrations caused by modulation of neuronal activity. Recent progress in signal processing and advances in system design, such as miniaturization, wearability and system sensitivity, have strengthened fNIRS as a viable and cost-effective complement to functional Magnetic Resonance Imaging (fMRI), expanding the repertoire of experimental studies that can be performed by the neuroscience community. The availability of fNIRS and Electroencephalography (EEG) for routine, increasingly unconstrained, and mobile brain imaging is leading towards a new domain that we term "Neuroscience of the Everyday World" (NEW). In this light, we review recent advances in hardware, study design and signal processing, and discuss challenges and future directions towards achieving NEW.

Figure 1.
The figure illustrates the growth of fNIRS publications from 1993 to 2019 as assessed on October 31st 2020, and our predictions for the period 2021 to 2024. The dashed black line represents the growing trend, and the black dots indicate the prediction (2017 to 2019) in our previous paper [6], showing that real publications in the last three years match well with the prediction. We expect the total number of fNIRS papers to continue to grow in the next several years as we illustrate with the magenta bars. This graph also highlights the growth of papers published utilizing multimodal measurements or wearable fNIRS since its first implementation in 1998. These statistics were obtained from a database created by a Web of Science search with the search terms ‘fNIRS’ and ‘brain’. ‘Multimodal’ refers to synchronous measurements of fNIRS and other neuroimaging modalities. Search keywords for multimodal fNIRS studies were a combination of ‘fNIRS’ and any one of the following words: ‘multimodal’, ‘bimodal’, ‘hybrid’ or ‘EEG’. Search keywords for wearable fNIRS studies were a combination of ‘fNIRS’ and any one of the following words: ‘wearable’, ‘wireless’, ‘fiberless’ or ‘modular’.
