Continuous EEG data were converted into the frequency domain using the Fast Fourier Transformation (FFT) with the following parameters: epoch = 2 sec, sample rate = 128 samples/sec (256 digital time points), frequency range = 0.5–40 Hz, and a resolution of 0.5 Hz with a cosine taper window to minimize leakage. Following the FFT, coherence values were calculated using the NG 2.6.1 program. To minimize the effects of windowing in the FFT61, an EEG sliding average of the 256-point FFT cross-spectral matrix was computed for each subject. The EEG data were edited by advancing in 64-point steps (75% overlap), recomputing the FFT, and continuing with the 64-point sliding window of the 256-point FFT cross-spectrum for the entire edited EEG record. The M, variance, S.D., sum of squares, and squared sum of the real (cosine) and imaginary (sine) coefficients of the cross-spectral matrix were computed across the sliding average of the edited EEG for all 19 leads for a total number of 81 and 1,539 log-transformed elements for each subject. The EEG values of each participant at each electrode were computed
