(a) fNIRS probe was embedded within an elastic, 128-electrode electroencephalogram (EEG) cap. (b) sensitivity profile for probe geometry and channel number. Sources are represented in red, detectors are represented in blue. Color scale indicates relative sensitivity in log 10 units from -1 (blue) to 1 (red).

Six ROIs were derived from the 12 channels located in each hemisphere: pre-central region, post-central region, superior parietal lobule (SPL), inferior parietal lobule (IPL), supra-marginal gyrus (SMG) and angular gyrus (AG).
