Figure 2
Spectral power changes averaged over 8 channels (P7, P3, Pz, P4, P8, O1, Oz, and O2) and plotted as 10log10 change over a baseline for target condition (a) and nontarget condition (b). (c) The comparison of ERSP between two conditions: red color indicates time-frequency regions significantly different between two conditions (, FDR corrected) and blue color indicates no significant difference.
