Figure 2

Optode placement during functional Near-Infrared Spectroscopy (fNIRS) assessments. fNIRS probe design was based on optode positioning in the international 10–20 space, and optodes were mounted in a modified electroencephalography cap in the corresponding position. Red dots represent light source, blue dots represent light detector optodes. Probe channels are shown as purple lines. The fNIRS probe and current figure was created with NIRSite 2020.7 (www.nirx.net).
