Table II.

Comparisons of numbers of frequency bins with significant EEG-EMG coherence between stages 1 and 2 among the five scalp areas and three muscles at beta frequency band. The data (mean ± standard error) were based on results of nine subjects with an additional criterion of having at least two adjacent coherence values higher than the 95% confidence level (see Results for details). BB, biceps brachii; BR, brachioradialis; TB, triceps brachii.
