Supplementary Figure 5. Motor confounds cannot explain the 13 Hz EEG power difference. The difference (calculated over the most significant 3 electrodes, as determined from Fig 3) between the EEG power spectrum during real vs. illusory motion perception (top) and the corresponding t-value (bottom) are plotted separately for the group of 6 subjects who pressed the left arrow key to report illusory motion (A) and those (6 subjects) who pressed the right arrow key (B). The peak difference at 13Hz is common, and has the same sign for both groups. The dashed red lines mark the p<0.05 significance threshold.

Supplementary Figure 6. Handedness is not correlated with the 13 Hz EEG power difference. The difference (calculated over the most significant 3 electrodes, as determined from Fig 3) between the EEG power spectrum during real vs. illusory motion perception (top) and the corresponding t-value (bottom) are plotted separately for the 3 left-handed subjects (A) and the 9 right-handed subjects (B). The peak difference at 13Hz is common, and of the same sign for both groups. The dashed red lines mark the p<0.05 significance threshold.
