Mental Task Evaluation for Hybrid NIRS-EEG Brain-Computer Interfaces

Figure 2

EEG and NIRS topology used in this study (adapted from [59]). EEG electrodes (black rectangles), NIRS detectors (red circles), and NIRS sources (green diamonds) were placed following the 10-5 system. NIRS channels are represented by dark straight lines connecting the sources to the detectors. Brain regions used to compute artificial NIRS channels are grouped in light blue.
