Means and standard (mean±S.E.) error of normalized percentage relative to highest power across all trials for all subjects in different configurations of stimuli. Y-axis shows average percentage relative to highest power. X-axis indicates stimulus conditions. A and b, 20–29 Hz frequencies band. No significant difference, from O2 and T6. 30–39 Hz band in c and d, occipital and parietal sites (O1, P3). 40–49 Hz band in e, site O2, compare with a and c. Above 60 Hz, in g, h, there was no significant difference,. F: inserted table showing configurations and sites yielding significant modulations. Significance levels computed relative to control, that is no shift O°. Neuman–Keuls test.
