From: Assessing the feasibility of online SSVEP decoding in human walking using a consumer EEG headset
The averaged power of SSVEP signals at O1 and O2 channels across 17 subjects under different walking speeds after alleviating the wideband noise by subtracting the power in the fixation-cross condition from that of the SSVEPs in the flickering conditions. The thin lines indicate the significant difference between speeds (p < 0.05 or < 0.01), whereas the error bars represent the standard error of the SSVEP amplitudes.
