Stimulus signals and the corresponding average SSVEP signals at 8 Hz, 24 Hz, and 40 Hz across all subjects. (a) Sampled sinusoidal stimulation signals. (b) Averaged SSVEP signals across 9 channels with a duration of 0.5 s. (c) Averaged SSVEP amplitude spectra across 9 channels. (d) Topographic maps on the amplitude of SSVEPs at the fundamental frequency for all channels on the scalp. The Chebyshev Type I band-pass filters in (b) and (d) were configured with the parameters [f-0.2, f + 5] Hz, while the band-pass filters in (c) were set to [f-0.2, 90] Hz to preserve harmonic responses, where f represents the stimulus frequency.
