Table 2.
Optimal source-detector pair groups for each EEG channel. Calculations were made for 65 selected EEG positions based on the 10-10 EEG positioning layout. The EEG position corresponding to each source and detector position is labeled in parentheses. Source-detector pair groupings were thresholded at pairs. The correlation between the thresholded source-detector groups and their corresponding electrode has a mean value of .
