Figure 3. Grand Mean Checkerboard SSVEP Amplitudes at Elec- trode POz Assessed via <t>Morlet</t> Wavelet Time-Frequency Transfor- mations. Time 0 indicates checkerboard onset. (A) Grand mean ERP averaged across CBS, MD and control groups. Note that the P1 peak is truncated and actually extends to 7.67 mV. ‘‘Fix.’’ indicates the fixation displays, ‘‘ch.’’ indicates checkerboards without letter arrays, and the numbers ‘‘1’’ – ‘‘12’’ above the x-axis indicate letter arrays with concurrent checkerboard stimulation. Yellow shading indicates the period analyzed in the foregoing FFT analyses. (B) Time-frequency amplitude heat map of the grand mean ERP averaged across groups. (C) Time-frequency subtraction heat maps. Superimposed black bars indicate statistically significant differences between the groups as determined via permutation testing (a = .05, two-tailed and corrected for multiple compari- sons across fundamental frequencies and contrasts). See also Figure S3.
