Table 4A.
Clusters results of AverageDifference across 24 frontocentral channels.

Note 1: means with standard deviations in parentheses. Note 2: In each channel, significant difference between the two cluster means (t-test, p-value < 0.05) was shown in bold. Note 3: In each cell, AverageDifference and standard deviations denote E5 (10^5).
