Using PLI as an indicator of phase consistency across trials, we first compared all four conditions in repeated-measures ANOVA including factor Condition with four levels: Warning, Go, NoGo, and Neutral. A four-way repeated measures ANOVA (Condition×Antero-Posterior×Laterality×Time Interval) revealed a significant main effect of all factors and also significant interactions between all these factors for both delta and theta frequency bands (see Table 1 for details). Since our main focus was on the comparison between Go and NoGo conditions, these results will not be further discussed.
