Correlation between resting theta activity and decomposed event-related potentials (ERPs) during correctly rejected Nogo trials in the C-cluster. (a) Correlation between resting theta activity and each time point of the EEG signal in the C-cluster from 200 ms before stimulus onset to 1000 ms after stimulus onset for the electrodes Cz and FCz. Only significant correlations with p ≤ .05 after a channel-by-channel correction with the false discovery rate method are shown. The correlation coefficient r is indicated by color. (b) Grand average of the participants’ ERPs in the C-cluster for the electrodes Cz (blue) and FCz (orange) from 200 ms before stimulus onset to 1000 ms after the stimulus onset. (c) sLORETA plots depicting activation differences in the superior parietal cortex (BA7) after contrasting the Nogo condition (correct rejections) in the C-cluster against zero. The color bar shows the critical t-values (p < .05, corrected for multiple comparisons).
