Figure Legend:
(A) Grand-average amplitude spectrum obtained by Fourier analysis of SSVEP waveforms elicited under the three attention conditions averaged across a cluster of 4 occipital electrodes. Peak amplitudes are located at the two stimulation frequencies. (B) Spline-interpolated voltage maps of SSVEP amplitudes for each RDK (i.e., stimulation frequency) averaged across all subjects and the three experimental conditions. The blue ellipses indicate the electrode cluster chosen for statistical analysis. (C) Statistical parametric maps of the estimated cortical current-density distributions that give rise to the SSVEP-amplitude increases for attended versus unattended dots (difference between attend red and attend blue conditions) for both RDKs. Scale represents t 2 values, and the p < threshold for the attended versus unattended comparison corresponds to Thresholds were corrected for multiple comparisons.
