“…Technical progress has also made it possible to combine EEG with functional NIRS (fNIRS), another non-invasive method. This method, we refer to as EEG+fNIRS, yields similar measurements with lower space but higher time resolution, in a far more practical and cost-effective arrangement (Buccino et al, 2016;Giacometti and Diamond, 2013;Keles et al, 2014;Koch et al, 2006Koch et al, , 2008Koch et al, , 2009Roche-Labarbe et al, 2008;Safaie et al, 2013). The utility of fNIRS as an independent modality for investigating the adult brain hemodynamics (Gentili et al, 2013;Mesquita et al, 2010;White et al, 2009) as well as infant development (Lloyd-Fox et al, 2010) is already well established.…”
