Time-domain N2 and P3 and TF-theta and TF-delta effects are presented in Figure 3. Wilcoxon Signed Rank tests comparing no-go and go trials indicated that while there was no effect of stimulus on the N2 peak at frontal-central sites (Z = -0.361, p = 0.718), no-go trials elicited a larger P3 than go trials at central sites (Z = 6.832, p < .001). For the TF-PCs, both theta and delta were larger for no-go stimuli than go stimuli (Zs = 6.136 and 6.532, respectively, ps < .001).
