Averaged topographic map of SNR at 60 different stimulation frequencies for (a) low modulation depth stimulus and (b) high modulation depth stimulus across all participants. Enlarged images for 8 Hz, 24 Hz, and 40 Hz are on the right. The epoch data were all passed through a Chebyshev Type I band-pass filter with the range [f-0.2, f + 5] Hz, where f represents the stimulus frequency.
