(a) Extraction of DFA exponent for a sample 4 s signal selected from S1 for a subject. (b) Mean and standard deviation of DFA values for selected channels in different frequency bands. At this test, the channels and the frequency bands which meet the higher level of statistical significance (p < 0.005) were selected. (c) Intergroup averaged-α computed for all consecutive 4 s signal segment for the C4 channel in each recorded data.
