Influence of 50 Hz noise. Influence of 50 Hz noise on TE analysis. Results of permutation testing (top) and the appropriate shift tests bottom for the original dataset (black), after adding 50 Hz noise to the data (gray), and after filtering out 49-51 Hz (white) of 100 datasets each. (Left) Analysis X → Y, the direction in which coupling was present; (Right) Analysis Y → X.
