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

Figure 4

Average HbO, HbR, and HbT maps for each task. Reported HbO, HbR, and HbT values are normalized to their baseline values and averaged across the time window spanning 10 to 15 seconds after stimulus onset. Red represents an increase in concentration of the chromophore, while blue represents a decrease (in mmol/L).
